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

This is a used, professionally tested drive. Condition: Used, Tested. Every unit in this lot passed a full verification pass before listing, including.

Power-on hours across the available lot range from 43,679 to 55,885 hours. All six units ship with a 3-month seller warranty. Power cycle counts range from 87 to 124 across the lot, and all units show 0 reallocated, 0 pending, and 0 uncorrectable sectors with clean SMART data. Random 4K read/write IOPS measured at approximately 0.2k/0.2k, consistent with expected performance for a 7200 RPM enterprise HDD under random I/O.

Drives are cosmetically used with normal handling wear from data center service; no physical damage affecting function. Photos show the actual unit(s) you will receive; any identifiers visible in images have been altered and serial numbers are not disclosed in this listing or on request, per our data-handling policy.
