Used enterprise drives are selling at or near original retail right now. The 8TB drive you bought for around $140 in 2023 is worth roughly $123-164 today, anchored to a live refurbished price of about $205. The AI-driven shortage flipped the usual depreciation curve: a drive bought a year ago is, in most capacities we track, worth more today than the depreciation schedule said it would be — with new drives scarce, the drives already in your NAS have held and in some capacities gained value. Our own daily price series starts in March 2026, so the multi-year comparison above is anchored to reported retail rather than measured by us; what we measure is the live refurbished price the estimate is built from. That is money you can put straight toward an upgrade.

Ranges are 60-80% of today's refurbished-with-warranty price, our live anchor and the ceiling for a bare used drive. Rows without a live refurbished listing show "insufficient market data" rather than a guessed number. These are estimates for a typical enterprise or NAS drive in good health — always verify against eBay sold listings for your exact model, brand, and SMART condition before buying or selling.
Hard drives are supposed to depreciate. For decades the pattern held: buy a drive, use it for a few years, sell it for a fraction of what you paid as newer, denser, cheaper models arrived. The 2026 shortage broke that pattern. Western Digital confirmed it is sold out of hard drives for the entire year at the hyperscale level, Seagate has been running at roughly 50 to 66 percent fill on channel orders, and the enormous storage appetite of AI datacenter buildouts consumed new production 12 to 18 months ahead of deployment. New drives became scarce and expensive almost overnight.
When the new-drive channel tightens, demand does not vanish — it flows to the secondary market. Buyers who cannot get new Exos or Ultrastar drives at a reasonable price turn to refurbished datacenter pulls and used drives from individuals, and that surge in secondary demand pushed prices up until, in several capacities, a used or refurbished drive now costs at or near what a new one did before the shortage. The market effectively inverted: installed drives became appreciating assets. For the full supply picture, see our reporting on WD selling out of hard drives and where stock still exists on where to buy.
Capacity is the dominant factor by a wide margin. A used 16TB drive is worth several times a used 4TB drive regardless of anything else, because buyers are paying for terabytes. That is why our value table is organized by capacity first — it is the single variable that explains most of the price. Everything below adjusts a drive up or down within its capacity band.
Brand and pedigree matter next. Enterprise lines — Seagate Exos, WD Ultrastar, HGST, Toshiba MG — hold value better than consumer drives because of their workload ratings and reliability reputations; HGST in particular commands a premium for its long track record of low failure rates. Condition and SMART health set your position within the range: a drive with zero reallocated sectors, no pending sectors, and a clean error log sits at the top even with high power-on hours, while any reallocated sectors drag it to the bottom. Recording technology is a hard gate — CMR drives carry a clear premium over SMR because buyers refuse SMR for NAS and RAID rebuilds (see CMR vs SMR). Finally, enterprise versus consumer positioning and any remaining original warranty each add a few points to what a careful buyer will pay.
eBay is the default and usually the best venue for individuals. Its enormous buyer base means single enterprise drives sell quickly, and its completed-listings history is the single most useful pricing tool you have: filter to sold listings for your exact model and you will see what real buyers actually paid this month, which beats any estimate including ours. The trade-off is fees and shipping — budget roughly 13 percent in seller fees plus packaging — and the reality that large lots of 50-plus drives are much harder to move on eBay than singles or small bundles.
For enthusiasts, r/hardwareswap and homelab forums reach buyers who understand datacenter pulls and do not need to be educated on power-on hours — transactions are faster and fee-free, though the audience is smaller and expects fair prices. Local marketplaces like Facebook Marketplace or Craigslist eliminate shipping risk and let the buyer inspect the drive in person, which works well for higher-value drives you would rather not mail. ITAD firms — IT asset disposition companies — buy used enterprise gear in bulk, but they price for volume and typically want lots around a thousand dollars or more; they are the right channel for a decommissioned rack, not for the four drives you pulled from a home NAS. Match the channel to the quantity: singles and small bundles to eBay or forums, true bulk to ITAD.
Never sell a drive with readable data on it. Deleting files or doing a quick format leaves the data fully recoverable — the only safe approach is a full-disk erase. For a hard drive, an ATA Secure Erase issued through the drive's firmware is the cleanest option; a single-pass overwrite of the entire disk with a tool such as DBAN, or the erase function built into most NAS operating systems, is equally sufficient. Multi-pass overwrites are unnecessary for modern drives and only waste time.
Do the wipe in the right order: check SMART first, while the drive still has its history intact, so you can record power-on hours and confirm zero reallocated sectors for an honest listing — then erase. An honest health disclosure protects your reputation as a seller and reduces returns, and it is exactly the information a knowledgeable buyer wants before committing. A clean SMART screenshot attached to a listing routinely lifts the final price toward the top of the range.
There is an honest counter-argument to selling everything. In a shortage, a known-good spare has genuine insurance value. If a drive in your array fails next year and prices are still elevated — or higher — replacing it may cost more than you would net by selling that same drive today. Keeping one or two cold spares of your array's capacity means a failure is a five-minute swap from the shelf rather than a scramble to buy at whatever the market charges. Sell the surplus into today's strong market, but hold back enough spares to cover a realistic failure or two. Whether prices climb further or ease is the open question — see our price forecast for the current trend before you decide how many to keep.
A used 8TB enterprise or NAS drive is worth roughly $123-164 in the current market, anchored to today's live refurbished-with-warranty price of about $205. That refurbished price is the ceiling because a warrantied, tested drive is worth more than a bare used one; the 60-80% range reflects the spread between a fast private sale and a patient one. Confirm against eBay sold listings for your exact model, brand, and health.
The 2026 shortage inverted the market. Western Digital is sold out of hard drives for the year at the hyperscale level, Seagate is running at partial fill, and AI datacenter demand absorbed new production well ahead of schedule. With new drives scarce and expensive, buyers moved to the secondary market, pushing used and refurbished prices up to levels at or near original retail. Installed drives have effectively appreciated — the drive you have been running for two years may be worth close to what you paid.
For individuals, eBay is the most reliable venue — price against completed sold listings and single drives sell quickly. Homelab communities such as r/hardwareswap and dedicated forums avoid fees and reach knowledgeable buyers. Local marketplaces remove shipping risk. ITAD (IT asset disposition) firms only take bulk lots, usually with a four-figure minimum, so they rarely make sense for a handful of drives from a home NAS.
Yes, always. Perform a full-disk erase before any sale — an ATA Secure Erase or a single-pass overwrite with a tool like DBAN is sufficient for a hard drive. A quick format or deleting files does not remove the data. Check SMART health first so you can list the drive's power-on hours and reallocated sector count honestly, then wipe. Never sell a drive with readable data on it.
Somewhat, but capacity dominates value far more than hours. Buyers of used enterprise drives expect meaningful runtime — datacenter pulls routinely have 25,000 to 45,000 power-on hours and still sell well. What buyers penalize hardest is any reallocated or pending sectors in SMART data. A high-hours drive with zero reallocated sectors and a clean SMART log sits near the top of the range; a low-hours drive with reallocated sectors sits at the bottom.
Generally yes, at the same capacity. Enterprise drives (Seagate Exos, WD Ultrastar, HGST, Toshiba MG) carry higher workload ratings, longer original warranties, and a reputation for reliability that buyers pay for on the secondary market. CMR recording is another premium: buyers actively avoid SMR drives for NAS and RAID use, so a CMR enterprise drive commands more than an equivalent-capacity SMR consumer drive.
It is a genuine trade-off in a shortage. Selling captures cash now while prices are elevated. Keeping a known-good drive as a cold spare has real insurance value: if a drive in your array fails next year, replacing it could cost more than you would get for selling today. The honest answer depends on how many spares you already have and how critical your array is — keep one or two cold spares, and sell the rest into the strong market.
