About this item
Overview: This is a HGST (Sun/Oracle OEM) Ultrastar-series 4TB SAS 6Gb/s enterprise hard drive, part number HUS724040ALS640/H7240AS60SUN4.0T. These drives are pulled from decommissioned enterprise storage arrays, individually tested, and wiped prior to sale. We have 2 units available; this listing is for one drive, and the buyer selects a condition/warranty tier on the product page.
Condition: Each drive in this lot has been individually tested on our rig prior to listing. Both units passed SMART health checks with 0 reallocated sectors, 0 pending sectors, and 0 uncorrectable sectors, and both completed an extended self-test without error. Power-on hour odometers were cross-checked against drive logs for accuracy. All data has been securely erased using scsi_format_unit and verified wiped.
Power-on hours across the lot range from 17,799 to 20,397 hours. Measured sequential throughput was 176-188 MB/s read and 175 MB/s write; random 4K IOPS measured approximately 0.2k read / 0.2k write, consistent with normal spinning-disk performance for this drive class and not indicative of any defect.
Exact serial numbers, WWNs, and seal numbers are not published for security reasons; photos show the actual physical unit(s) offered, though on-drive identifiers visible in images have been obscured.
Shipping & Returns: Ships within 1 business day in protective anti-static packaging with foam padding to prevent shock damage in transit. We offer a 30-day return window for any reason. Additionally, the drive carries our stated seller warranty (12 or 24 months depending on the usage tier selected at checkout) covering defects in the tested unit.
