Condition
This drive is in used, tested condition. Each unit has been individually tested prior to listing:
- Reallocated sectors (SMART attribute 5): 0 — no bad sectors remapped; 0 pending, 0 uncorrectable
- SMART extended (long) self-test: Passed, completed without error
- Power-On Hours: 48,400 to 48,700 hours per drive (a high-hours drive, priced accordingly). Hours are cross-checked against the drive's own internal logs; we never reset counters
- Read/write benchmarking: Passed
- Data: Wiped and verified — no previous data remains
Each drive is sealed after testing with a numbered tamper-evident seal and ships with a printed test certificate for that exact unit (model, serial number, power-on hours and test result). Covered by our 3-month warranty. Cosmetic wear may be present on the chassis; this does not affect function. Photos show a representative unit with identifiers masked. Model in any system with a 3.5-inch SATA bay: NAS units (Synology, QNAP, TrueNAS, Unraid), servers, JBODs and desktops. SAS controllers and backplanes also accept SATA drives. Verify your enclosure or USB dock supports drives of this capacity before purchasing; some older units top out at 16TB or below.
Shipping & Returns
Ships within 1 business day of payment. Drives are double-boxed and padded with anti-static and foam protection for safe transit. 30-day returns accepted — if the drive fails SMART or shows issues on arrival, we will replace or refund, no hassle. Buyer pays return shipping for remorse returns; seller covers return shipping for DOA claims.
