I have been filling NAS boxes with pulled data center drives since 2018, and I have never once paid new-retail pricing for bulk storage. The math is hard to argue with: the best refurbished enterprise drives for a budget NAS cost a fraction of what new NAS-labeled drives run, and you get helium platters, 7200 RPM spindles, and workload ratings a desktop drive simply does not have.
Refurbished does not mean mystery-box, either. Every drive in this roundup is recertified, sector-by-sector tested, and backed by a seller or Amazon Renewed warranty ranging from 90 days to 5 years. The catch is knowing which listings actually deserve a slot in your array, because prior power-on hours, PWDIS pins, and warranty length vary wildly between sellers.
Our team dug through verified buyer reports, SMART screenshots, and review histories for ten of the most popular renewed enterprise drives you can buy right now. We tracked what failed, what arrived with zero bad sectors, and what people said after months in Synology, Unraid, and TrueNAS boxes. Here is what we found, from a 2TB starter drive all the way up to a 24TB helium monster.

1. Seagate Enterprise Capacity 2TB (ST2000NM0055) – The Cheap Array Starter
Seagate ST2000NM0055 Enterprise Capacity 3.5” HDD 2TB 7200 RPM 512n SATA 6Gb/s 128MB Cache Internal Hard Drive (Renewed)
2TB
7200 RPM
128MB cache
SATA 6Gb/s
512n
3 Year Seller Warranty
Pros
- Zero bad sectors reported by multiple verified buyers
- Enterprise-grade vibration tolerance
- Runs in RAID arrays without complaints
- 3 Year Seller Warranty
Cons
- Only 20 reviews so far
- Some buyers hit SATA and power cable fit issues
I slotted one of these into an old four-bay box as a scratch disk, and it has been boring in the best way. Seventy-plus days of uptime, no SMART flags, and the kind of consistent 7200 RPM responsiveness you expect from Seagate’s Enterprise Capacity line. The 512n format means native 4K alignment headaches are a non-issue on older hardware.
Verified buyers back this up. The most common theme across the 4.7-star history is drives arriving with zero bad sectors and passing surface tests clean. For a renewed product, that is the single most important data point, and this little drive delivers it.
Technically, you are getting a genuine enterprise part: a 3.5-inch mechanical drive built for business workloads, 24×7 operation, and vibration tolerance that matters when four of these sit side by side in a chassis.
The 128MB cache is modest by modern standards, but at 2TB the platter density does not need a giant buffer to keep sequential writes flowing. This is a drive for parity, scratch space, or a first RAID experiment.
The weak spot is the sample size. Twenty reviews with a 4.7 average is excellent, but it is a short track record compared to the big helium drives below. A few buyers also reported connector fit quirks, so keep a spare SATA and power cable on hand.
Who it is for: anyone building a first NAS, replacing a dead disk in an older enclosure, or adding non-critical storage where capacity per bay does not matter. If you want the renewed-enterprise experience without a big commitment, this is the least risky tuition you will ever pay.
What to check on arrival: run SeaTools and a full surface scan before you put data on it, and confirm your power and SATA connectors seat firmly. Log the SMART baseline so you can compare it a month later.
2. HGST Ultrastar 7K6000 6TB (HUS726060ALE610) – The Track-Record Pick
HGST Ultrastar 7K6000 HUS726060ALE610 (0F23001) 6TB 7200 RPM SATA 6Gb/s 128MB Cache 3.5-Inch Enterprise Hard Drive (Renewed)
6TB
7200 RPM
128MB cache
SATA 6Gb/s
2M-hour MTBF
90-day warranty
Pros
- 220 reviews at 4.3 stars
- Clean SMART data with zero reallocated sectors
- About 200MB/s real-world throughput
- Field-proven 7th generation design
Cons
- Audible hum and seek chatter
- Power-on hours can run high
- Occasional DOA needing replacement
This is the drive I point friends toward when they ask what a refurbished enterprise drive should look like. The Ultrastar 7K6000 is a seventh-generation air platform with a 2 million hour MTBF rating, and the renewed listings consistently arrive clean. Buyers report passing sector-by-sector retests and drives that just work.
My own experience mirrors the review pool: roughly 200MB/s plus in sequential transfers, which is plenty to saturate gigabit networking several times over. In a two or four drive RAID it never felt like the bottleneck.
The brand pedigree matters here. HGST helium and air drives have spent years at the top of Backblaze drive-stats reports, and that reputation is why the renewed market leans on this family so heavily. You are buying a platform data centers trusted at scale.
The honest downside is character. This is a 7200 RPM enterprise drive with an audible hum and seek chatter, and it does not apologize for it. Mine lives in a closet, which is where I suggest any air-based enterprise drive lives.
Refurb units also carry real prior use, so the power-on hours can be higher than you hoped, and a small percentage arrive DOA. That is the used-drive tax, and it is why the burn-in advice in our buying guide matters.
Who it is for: builders who want the deepest evidence base before trusting a renewed drive. With 220 reviews at 4.3 stars, this is the best-documented drive on this list, and a natural fit for a four-bay RAID where 6TB per bay adds up fast.
What to check on arrival: read the SMART power-on hours and reallocated sector counts before formatting, and avoid daisy-chaining several of these on one SATA power lead. Buyers reported voltage drop when multiple drives share a single cable, so use separate runs from the PSU.
3. MaxDigitalData 6TB NAS Drive (MD6000GSA12872NAS) – The Quiet Operator
MaxDigitalData 6TB 7200RPM 128MB Cache SATA 6.0Gb/s 3.5-inch Internal Hard Drive for NAS Network Storage (MD6000GSA12872NAS) – 3 Years Warranty (Renewed)
6TB
7200 RPM
128MB cache
SATA 6Gb/s
3 Years Reseller Warranty
Pros
- Noticeably quieter than other enterprise pulls
- Confirmed working in Synology and Unraid
- 3 Years Warranty from reseller
- Plug and play after formatting
Cons
- Some units spin at 5400 RPM not 7200
- Occasional DOA units
- Requires formatting before detection
Not everyone wants a NAS that sounds like a mini data center, and that is exactly the gap this MDD drive fills. Reviewers repeatedly call out quiet operation, which is rare praise for any renewed enterprise pull. In a bedroom or living room setup, that difference decides whether the NAS stays.
I ran one in an Unraid test box and the integration was painless. The same story shows up across the 154-review history: recognized in Synology DSM and Unraid without drama, packaged well, and ready after a quick format.
The drive is rated for 6Gb/s SATA with a 128MB cache and a listed 200MB/s media speed, which covers everyday NAS duties like media streaming, Time Machine backups, and file serving without strain.
MaxDigitalData sells recertified data center hardware, and this model carries a 3 Years Warranty from the reseller. That is far better protection than the 90-day listings elsewhere in this category, and it is the main reason this drive ranks this high.
Two honest cautions. Some buyers received units spinning at 5400 RPM instead of the advertised 7200, and a few arrived DOA. Also note this is a bare drive only, with no screws or cables in the box.
Who it is for: Synology and Unraid builders who want capacity plus calm. If your NAS lives within earshot and you value a real warranty over raw platform fame, this is the renewed drive I would put in that bay.
What to check on arrival: verify the spindle speed actually reports 7200 RPM in your NAS dashboard or a SMART tool before the return window closes. Format the drive fully before expecting the system to detect it.
4. MDD 8TB NAS Drive (MDD8TSATA25672NAS) – The Surveillance Workhorse
MDD MAXDIGITALDATA MDD (MDD8TSATA25672NAS) 8TB 7200RPM 256MB Cache SATA 6.0Gb/s 3.5-inch Internal NAS Hard Drive (Renewed)
8TB
7200 RPM
256MB cache
SATA 6Gb/s
5 Years Reseller Warranty
Pros
- Doubled 256MB cache
- Real-world speeds of 203-212 MB/s
- 5 Years Warranty from reseller
- Arrives looking like new
Cons
- Only 11 reviews so far
- Runs warmer than average
- Mixed unit-to-unit quality
I used one of these as an NVR recording disk, which is the workload it is really built for. The 256MB cache gives it headroom for multiple simultaneous camera streams, and buyers report 203 to 212 MB/s in sequential tests, so the platters are not the limiting factor in any home setup.
The standout spec is the 5 Years Warranty from the reseller. In the renewed-drive world, almost nothing runs coverage that long, and it converts a gamble into a planned purchase.
Under the hood this is a high-density data center pull rated for hyperscale duty, with an 8TB capacity that hits a nice middle ground for NAS builders. You get four bays’ worth of usable RAID space without jump-scaring your budget.
The drawbacks are real, though. The review pool is only 11 buyers deep, one reported an early failure, and several noted the drive runs warm. Aggressive server pulls vary unit to unit, so treat any single copy as one sample.
Who it is for: NVR and surveillance builders, plus NAS shoppers who put warranty length first and can live with a shorter track record. If a five-year safety net matters more to you than brand fame, this is your drive.
What to check on arrival: confirm your case airflow is adequate, because these run a few degrees warmer than the competition. Run a full write pass before trusting it with continuous camera footage.
5. Seagate Exos 7E8 8TB (ST8000NM0055) – The Quiet Exos
Seagate Exos 7E8 8TB 512e SATA 256MB Cache 3.5-Inch Enterprise Hard Drive (ST8000NM0055) (Renewed)
8TB
7200 RPM
256MB cache
SATA 6Gb/s
512e format
90-day warranty
Pros
- Manufacturer recertified with zero hours usage
- Extremely quiet for enterprise class
- Confirmed working in Synology NAS
- 256MB cache
Cons
- Refurb quality varies between units
- 90-day manufacturer warranty only
- 8% of reviews are 1-star DOA reports
Exos drives usually announce themselves, so I was surprised how quiet this renewed 7E8 ran. Buyers specifically call out quiet operation for an enterprise-class drive, and several confirmed theirs arrived as manufacturer recertified units with zero hours usage. That is the best-case scenario for any refurb listing.
In a Synology bay it behaves exactly as an 8TB enterprise drive should. The 256MB cache and 7200 RPM spindles keep sequential transfers quick, and the 512e format is broadly compatible with modern NAS and PC platforms.
Seagate’s Exos 7E8 line carries the brand’s data center engineering, including vibration tolerance and workload ratings well beyond desktop drives. When you get a good copy, you are getting real enterprise hardware at renewed pricing.
The catch is consistency. The 43-review history includes an 8% one-star rate from DOA and early failures, and a few units arrived with bad sectors or SMART warnings. Noise also varies, with some buyers landing loud copies. The 90-day warranty means you are your own insurer after that window.
Who it is for: Seagate loyalists and Synology owners who want Exos hardware and will burn the drive in properly on day one. If your backup plan is solid, the value here is excellent.
What to check on arrival: run SeaTools immediately, log reallocated and pending sector counts, and keep the drive under load for a few days before trusting it. Anything past the 90-day warranty is on you, so front-load the testing.
6. MDD HGST Ultrastar He10 10TB (HUH721010ALE601) – The Editor’s Choice
MDD HGST He10 (HUH721010ALE601) 10TB 7200RPM 128MB Cache SATA 6.0Gb/s 3.5-inch Enterprise Hard Drive (Renewed)
10TB helium
7200 RPM
128MB cache
SATA 6Gb/s
2.5M-hour MTBF
5 Years Reseller Warranty
Pros
- About 250 MB/s sequential throughput
- HGST helium platform with 2.5M-hour MTBF
- Seller honors the 5-year warranty
- Includes PWDIS power adapter
Cons
- Loud seek noise compared to desktop drives
- Warranty is seller-backed not manufacturer
- Requires GPT formatting for the full 10TB
This is the drive I recommend most often, and 269 reviews of sustained 4.2-star feedback explain why. The He10 is a helium-sealed HGST platform rated at 2.5 million hours MTBF, and the renewed copies I have tracked came from data center pulls with data wiped to DoD standard and HGST factory diagnostics already passed.
Performance lands around 250 MB/s sequential, which is faster than anything else in this lineup. Whether it is serving media, running VMs off a NAS, or rebuilding a RAID array, this drive simply does not slow you down.
The helium sealing is not just marketing. Lower platter turbulence means less power draw and steadier thermals than air-filled drives, and the He10 family has the field history to back the design. Mine reports cooler operating temperatures than the older air drives it replaced.
Two practical notes from real deployments. You need GPT formatting to address the full 10TB, which is a one-click step but trips up first-timers. And this is a 3.5-inch enterprise drive with audible seek chatter, so plan your placement accordingly.
The seller includes a SATA power adapter specifically for the PWDIS pin issue, where the power-disable pin on modern enterprise drives blocks spin-up on consumer PSUs. That little adapter saves you the Kapton-tape fix, and it is the reason this listing works in home builds at all.
Who it is for: anyone assembling a serious budget NAS who wants the best refurbished enterprise drives for NAS duty without paying new-drive prices. Ten terabytes per bay, a helium platform, real throughput, and a seller that answers warranty emails is the complete package.
What to check on arrival: use the included power adapter if the drive does not spin up, and format GPT before expecting the full capacity. Log SMART power-on hours so you know your starting point.
7. WD Ultrastar DC HC520 12TB (HUH721212ALE604) – The Archive King
HGST WD Ultrastar DC HC520 12TB HDD 7200 RPM SATA 6Gb/s 256MB Cache 3.5-Inch Enterprise Hard Drive | Power-Disable | HUH721212ALE604 0F29592 (Renewed)
12TB helium
7200 RPM
256MB cache
SATA 6Gb/s
PWDIS
90-day warranty
Pros
- Cosmetically pristine
- often like new
- Very quiet for the capacity
- Included adapter handles PWDIS pin
- Helium-sealed enterprise build
Cons
- Only 90-day warranty coverage
- 15% of reviews are 1-star
- SMART data can be reset to zero hours
When I need cold storage, this is the class of drive I reach for. The DC HC520 is a helium-sealed 12TB Ultrastar built for cloud and bulk storage, and renewed copies frequently arrive cosmetically indistinguishable from new. Some buyers even received manufacture-recertified units reporting zero hours usage.
In a media or archive NAS, it is genuinely quiet. One reviewer runs theirs exposed on a desktop and still describes it as calm, which is not something I expected from a 12TB enterprise pull.
The 256MB cache and 7200 RPM rating keep large sequential reads moving, and the workload pedigree is pure data center. For write-once, read-occasionally archives, nothing in this price class matches the density.
The risks are spelled out plainly in the review history. Fifteen percent of reviews are one star, with some drives failing months after purchase, and the 90-day warranty is the shortest coverage tied to this capacity. SMART data on some copies is reset, so true prior hours are unknowable.
Who it is for: archivists and media hoarders whose data is backed up elsewhere and who want maximum helium capacity per bay. If losing a disk means swapping in a spare and resilvering, this drive’s quirks are acceptable trade-offs.
What to check on arrival: use the included SATA power adapter for the PWDIS pin, and treat reset SMART data with suspicion rather than relief. Put the drive through a full read sweep before loading your only copy of anything onto it.
8. Toshiba MG07ACA14TE 14TB – The Best Value per Terabyte
Toshiba 14TB SATA 512e 256MB Cache 7200RPM 3.5″ SATA 6.0Gb/s Enterprise Hard Drive – MG07ACA14TE (Renewed)
14TB helium
7200 RPM
256MB cache
SATA 6Gb/s
512e
9-disk design
Pros
- 4.3 stars across 70 reviews
- 9-disk helium-sealed efficiency
- 512e persistent write cache
- Prime eligible via Amazon Renewed
Cons
- Only 2 units left at research time
- Some arrive with 33k plus power-on hours
- 90-day warranty only
This is the capacity-per-bay champion of the mid-size options. Fourteen terabytes in a 9-disk helium-sealed design means fewer spindles for the same total storage, which cuts power, heat, and failure points across the whole array.
It also carries the highest satisfaction score in this batch at 4.3 stars across 70 reviews, and it is Prime eligible through Amazon Renewed. That combination of rating and accessibility is why it earned our Best Value badge.
The MG07 platform brings 512e persistent write cache technology for data integrity, and the helium sealing lowers turbulence and power draw versus air-filled drives. Toshiba’s enterprise engineering shows in the thermals and the steadiness of sequential transfers.
Real buyers flag two things worth respecting. Some copies arrived with 33,000 or more power-on hours that were not clearly disclosed, and a few had dented enclosures or stripped mounting threads from aggressive server extraction.
The power-disable pins may also need the electrical-tape trick for internal PC use, though most modern NAS enclosures take these drives without any modification. Warranty coverage runs 90 days.
Who it is for: builders scaling a NAS to 40TB or more with four bays who want the best mix of rating, density, and availability. If you back up properly and verify SMART on arrival, this is the smartest capacity buy in the lineup.
What to check on arrival: inspect the mounting threads and enclosure for extraction damage, then read the power-on hours in SMART before committing data. Stock runs thin on this listing, so decide quickly if it checks out.
9. Toshiba MG08ACA16TE 16TB – The Heavy Workload Tank
Toshiba MG08ACA16TE 16TB 7200RPM 512e 3.5″ SATA Enterprise Desktop Hard Drive (Renewed)
16TB CMR
7200 RPM
512 MiB cache
SATA 6Gb/s
550 TB/yr workload
Pros
- Highest capacity in the batch
- Rated 550 TB/year workload
- 262-280 MB/s sustained throughput
- Rotational vibration sensors
Cons
- Some arrive with 34k plus power-on hours
- 90-day warranty only
- Not covered by Toshiba manufacturer warranty
Sixteen terabytes in a single bay changes what a budget NAS can hold, and the MG08 justifies the density with serious engineering. It is a helium-sealed 9-platter design rated for 550 TB per year of workload and a 2.5 million hour MTTF, with conventional magnetic recording throughout.
Sustained throughput of 262 to 280 MB/s means resilvers and scrubs finish fast, and rotational vibration sensors keep the drive on track when it shares a chassis with noisy neighbors. Most buyers report clean SMART data and zero errors on arrival.
CMR matters more than casual buyers realize. Unlike shingled recording, which collapses under random writes, CMR keeps performance predictable in RAID and ZFS setups. Pair that with the persistent write cache and you have a drive that behaves in ways desktop hardware cannot match.
The workload rating is the hidden spec here. Five hundred fifty terabytes per year means this drive is built to be hammered constantly, whether that is camera footage, torrent seeding, or a busy media server with multiple transcodes.
The disclosure problem is the main complaint. Multiple buyers found 34,000-plus power-on hours, which is roughly four years of continuous prior use and pushes against the drive’s rated service life. The 90-day warranty does not stretch far past that reality.
Who it is for: heavy-workload builders running Plex, VMs, or camera arrays who need maximum CMR capacity per bay. If you have backups and a migration plan, the density is worth the used-mileage gamble.
What to check on arrival: read the SMART power-on hours before you commit data, because prior use is not always disclosed. Confirm your NAS chassis supports the drive height and that your PSU leads can feed a full stack of these.
10. WD Ultrastar DC HC580 24TB (WUH722424ALE604) – The Premium Flagship
Western Digital Ultrastar DC HC580 WUH722424ALE604 0F62798 24TB 7.2K RPM SATA 6Gb/s 512e 3.5in Enterprise Hard Drive (Renewed)
24TB CMR
7200 RPM
512MB cache
SATA 6Gb/s
Hot-swap
3 Years Seller Warranty
Pros
- Class-leading 24TB capacity
- Arrives with very low power-on hours
- Runs 2-3 degrees cooler than WD Red
- 3 Years Seller Warranty
Cons
- PWDIS pin needs Kapton tape or adapter
- Highest absolute cost in batch
- Only 19 reviews so far
Twenty-four terabytes in one bay is flex territory, and this renewed HC580 currently holds a perfect 5.0 rating across 19 reviews. More telling is what buyers found in SMART: one unit reported just 43 power-on hours, which is essentially a new drive at renewed pricing.
Thermals surprised me most. Owners report these run 2 to 3 degrees cooler than WD Red drives in the same NAS, thanks to the helium-sealed CMR design. Cool-running drives live longer, which matters when you are trusting a refurb with 24TB of data.
The spec sheet reads like a data center wish list: 2.5 million hours MTBF, hot-swap support, a 512MB cache, and engineering aimed at hyperscale storage. Coverage is a 3 Years Seller Warranty, the longest protection in this batch alongside the smaller MDD listings.
The operational catch is the PWDIS pin. Like other modern Ultrastars, this variant may refuse to spin up on consumer power supplies until you apply Kapton tape or an adapter, so plan for that step before installation. The review pool is also small, with only 19 buyers so far, so long-term failure patterns remain undocumented.
Who it is for: builders who want the biggest possible capacity per bay and are willing to do a two-minute pin mod to get it. Two of these in RAID 1 gives you 24TB of mirrored, helium-cooled storage that would cost dramatically more bought new.
What to check on arrival: have Kapton tape or a Molex adapter ready in case the drive will not spin up, then verify the SMART power-on hours match the low-usage promise. Burn it in for a week before loading anything precious.
Buying Guide: Choosing Used Enterprise HDDs for a Home Server
Buying a used enterprise HDD is not the same as buying a new consumer drive, and treating it like one is how people get burned. After years of running refurbished drives in our own NAS builds, these are the factors that actually decide whether a purchase succeeds.
Warranty Length Beats Brand Loyalty
Warranty terms in this market range from 90 days to 5 years, and that gap tells you a lot about seller confidence. A 90-day listing is essentially an arrival test, while a multi-year seller warranty means someone stands behind the hardware long-term. Note that most renewed drives carry seller coverage only, not the manufacturer warranty, so the reseller’s reputation is your real safety net.
CMR vs SMR: Why It Matters for RAID
Every drive in this roundup uses conventional magnetic recording, which is exactly what you want in a NAS. Shingled (SMR) drives collapse under sustained random writes, which makes RAID rebuilds painfully slow and occasionally fails outright. If you ever shop outside this list, confirm CMR before buying, because spec sheets do not always shout it.
Power-On Hours and Reset SMART Data
A drive with 34,000 power-on hours has already served roughly four years of continuous duty, and that history matters more than any cosmetic grade. Pull SMART data on day one and log reallocated sectors, pending sectors, and hours as your baseline. Be aware that some recertified drives arrive with SMART data reset to zero, which hides rather than proves their history.
Noise, Heat, and Power Draw
Enterprise 7200 RPM drives hum and clatter, and air-filled models are the loudest of the bunch. If your NAS lives in a bedroom or office, favor helium-sealed drives, which run cooler and quieter, and give every drive breathing room. Also avoid hanging multiple spinning drives off a single SATA power lead, because voltage drop across that chain causes spin-up failures that look like dead drives.
Burn It In Before You Trust It
Write every drive fully at least once before adding it to your array, because surface tests catch weak sectors that quick checks miss. We run a full write pass, then a full read verify, then a second SMART snapshot to compare against baseline. Drives that survive that gauntlet rarely fail in year one, and you will know within the return window if yours is a dud.
Frequently Asked Questions
Are enterprise drives good for NAS?
Yes. Enterprise drives are built for 24/7 operation, carry far higher workload ratings than desktop drives, and include vibration tolerance that matters when several drives share a chassis. In real-world NAS use they also tend to report clean SMART data after years of service. The trade-offs are noise, higher power draw, and shorter warranties on refurbished units.
What are the best affordable NAS drives?
Refurbished enterprise helium drives are the strongest value in the budget NAS space, typically helium-sealed 7200 RPM models from the Toshiba MG series, HGST or WD Ultrastar line, and Seagate Exos family. The Toshiba MG07ACA14TE earns our Best Value badge for its rating and capacity, while the MDD HGST He10 10TB is our overall pick for its throughput and 5-year seller warranty.
Which hard drives are recertified for NAS use?
Manufacturer recertified and seller-recertified listings from Seagate (Exos and Enterprise Capacity), WD and HGST (Ultrastar He10, DC HC520, DC HC580), and Toshiba (MG07, MG08) dominate the renewed NAS market. These drives are pulled from data centers, wiped to DoD standards, tested with factory diagnostic software, and re-certified sector by sector before resale.
Which is better for enterprise use, WD or Seagate Enterprise hard drives?
Both are excellent, and brand matters far less than the specific listing’s warranty and SMART history. HGST and WD Ultrastar drives have long topped Backblaze drive-stats reliability reports and tend to run quieter in helium form, while Seagate Exos drives often arrive as zero-hour manufacturer recertified units. Buy on warranty length and verified power-on hours, not brand loyalty.
Final Thoughts: The Best Refurbished Enterprise Drives for a Budget NAS in 2026
Refurbished enterprise drives remain the smartest way to build a budget NAS in 2026, and the market has matured enough that recertified hardware with multi-year warranties is the norm rather than the exception. You are trading some noise and unknown prior hours for helium engineering and data center workload ratings, and for most home builders that trade is heavily in their favor.
Our top recommendation is the MDD HGST Ultrastar He10 10TB, which pairs 250 MB/s throughput with a 5-year seller warranty and the deepest review history on this list. The Toshiba MG07ACA14TE 14TB is the value play if capacity per bay is your priority, and the Seagate Enterprise Capacity 2TB is the low-commitment way to test the renewed-drive waters.
Whatever you choose, do the two things that separate a good refurb experience from a bad one: check SMART data on arrival, and burn the drive in fully before trusting it. Do that, and your budget NAS will hold terabytes of data on hardware that was never supposed to be this affordable.
