How we test used storage drives

This describes our testing process. Contact us for available unit-specific results before ordering.

  1. Step 1
    SMART health review

    Reallocated, pending and uncorrectable sector counters read from the drive itself.

  2. Step 2
    Extended self-test

    The drive's own long self-test, run to completion.

  3. Step 3
    Power-on hours cross-check

    Hours compared against the drive's internal logs. We never reset counters.

  4. Step 4
    Wiped

    All previous data is wiped and the wipe is verified.

  5. Step 5
    Tamper seal and certificate

    Sealed after testing with a numbered tamper-evident seal. Its QR code and the certificate in the box open this exact unit's report.

Condition notes

Used, pulled from a decommissioned server environment and fully tested prior to listing. Verified per-unit test results on file (1 of 1 units passed).

No physical damage, cosmetic wear consistent with prior data center use (light handling marks on the caddy area possible). Drive is fully functional and ready to deploy.
