Server hard drives are still the backbone of enterprise storage: nearline SAS and SATA drives from 1TB to 26TB that fill array backplanes, JBOD shelves and standard server bays at a price per terabyte flash cannot match. Every drive on this page is a genuine enterprise unit sold by exact manufacturer part number - Seagate Exos, Western Digital Ultrastar, Toshiba MG-series and the HPE, Dell, Lenovo and NetApp OEM-branded equivalents that ship in real systems, in the caddy your chassis expects. We list New, Recertified and Refurbished stock together with the live $/TB so a tested drive and a sealed one are an honest comparison for the same usable space. Use the capacity grid to jump to a size, the interface pages to split SAS from SATA, and the condition pages to shop by warranty class. In stock, fast US shipping, warranty-backed and purchase orders welcome - for a matched RAID set, use the bulk-quote link and we confirm firmware and trays first.
SAS for dual-port array backplanes and mission-critical duty; SATA for JBODs, NAS and standard server bays at the lowest cost per TB.
Every condition ships tested and warranty-backed. Recertified and Refurbished drives are where the $/TB gets hard to beat.
Every part is sold by exact manufacturer part number and ships warranty-backed. Here's what each condition means so you can weigh price against your workload.
Not sure which to pick? Read our New vs Recertified vs Refurbished guide.
New is factory-sealed with the full manufacturer warranty. Recertified is OEM-restored to specification with low power-on hours and our own warranty — the same capacity for a lower price. Refurbished is a tested, wiped working pull. All are sold by exact part number and warranty-backed.
Yes — these are enterprise/nearline hard drives built for continuous duty, with the workload ratings and error-recovery firmware desktop drives lack. Each product's spec table lists RPM and workload rating.
Yes — we ship fast from the US and welcome POs. For quantity or a matched set, use the bulk-quote link on any product for pricing and a compatibility check.
