Usage tiers
Graded by power-on hours, not by adjectives
Every certified used drive is placed in a tier by the hours on its own SMART power-on counter, the drive's odometer. Fewer hours means more rated life left. Every tier passes the same tests; the tier changes the price and the warranty, not the pass bar.
The five tiers
| Tier | Power-on hours | What it means | Typical use case |
|---|---|---|---|
| Open Box | under 100 hrs | Open box: unused, only burn-in and test hours on the clock. | When you want the most rated life left on the clock |
| Like New | 100-500 hrs | Essentially unused: burn-in and test hours only. | New arrays and NAS builds that should run for years |
| Light Use | under 20,000 hrs | Under 2.5 years of datacenter duty. | General server and NAS storage with plenty of life left |
| Standard Use | 20,000-40,000 hrs | Typical datacenter service. Best price per TB. | Bulk capacity where price per TB matters most |
| Value | over 40,000 hrs | The most hours, the same test results. Maximum savings. | Backup, archive and lab pools built with redundancy |
Why hours, not just “refurbished”
“Refurbished” tells you nothing you can measure. Power-on hours are a number the drive records itself, like the miles on a car. We read that number, print it on the certificate, and never reset or hide it, so the tier you buy is something you can check when the drive arrives.
Same tests in every tier
A Value drive and an Open Box drive clear the same bar: SMART health, extended self-test, zero bad sectors and a benchmark in range. A drive that misses it is not sold in any certified tier. The full criteria are on how we test.
Warranty by tier
Each tier carries its own warranty term, and terms vary by listing, so the exact term is shown on every tier card on the product page. Certified tiers carry up to 2 years; standard items carry 90 days. The warranty page covers what is included and how claims work.
Questions about tiers
Is the Value tier risky?+
Value drives carry the most hours, but they pass exactly the same tests as every other tier: SMART health PASSED, a clean extended self-test, zero reallocated, pending and uncorrectable sectors, and benchmark throughput in range for the model. The tier changes the price and the warranty term, which is stated on the listing, not the pass bar.
Why is Open Box cheaper than new?+
Open Box drives are unused, with under 100 power-on hours from burn-in and our own testing, but the factory seal has been broken, so they cannot be sold as new. You get nearly new hours without paying for a sealed retail box, with the same tests, certificate and public report as every certified drive.
How do you know the hours are real?+
They are read from the drive’s own SMART power-on counter, printed on the certificate in the box and shown on the unit’s public report. We never reset or hide them, and the counter stays on the drive, so you can read it yourself on arrival with any SMART tool.
Can I pick my exact units?+
Yes. Certified listings have an exact-unit picker on the product page: choose the units you want, read each unit’s test report first, and your order records exactly which units you picked.
Pick the hours that fit the job
Certified listings show every tier in stock with its price, price per TB and warranty, and an exact-unit picker if you want to choose the drives yourself.
