The HGST Ultrastar C10K1800 is a 1.8TB 10,000 RPM 2.5-inch enterprise SAS drive, here in its Dell-branded version (DP/N RF9T8). It is a common capacity drive for Dell PowerEdge servers and storage shelves. This is a SAS drive and requires a SAS host bus adapter, RAID controller or SAS backplane.

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: 19,000 and 21,300 hours on the two units. 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 12 to 24-month (by unit hours) warranty. Cosmetic wear may be present on the chassis; this does not affect function. Photos show a representative unit with identifiers masked. Bare drive, no caddy or tray.

Compatibility

Compatible with servers and storage shelves that provide a 2.5-inch SAS bay and a SAS controller or backplane, such as Dell PowerEdge, HPE ProLiant and Supermicro platforms. Not compatible with SATA-only ports, laptops or consumer NAS enclosures without a SAS controller. Your server's drive caddy is not included.

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.
