Dell 12TB 3.5-inch 7.2K SATA 6Gbps Hard Drive — 8JYD7

This is a 12TB 3.5-inch SATA hard drive spinning at 7.2K rpm over a 6Gbps SATA link, supplied under Dell part number 8JYD7 with a Seagate mechanism inside, maker model ST12000NM0128.

As a Dell-labelled drive it carries Dell firmware, matching what PowerEdge servers and PowerVault arrays are set up to use. Parity RAID levels set aside space for redundancy, so size arrays on usable capacity rather than the sum of the drives. It uses 512e sectors (4K physical, 512-byte emulated), which current RAID controllers and operating systems handle natively. High-capacity nearline drives like this suit backup targets, archives and file servers where capacity per bay matters most. When replacing a failed disk, match the capacity, speed and interface of the drives already in the array. Dell-labelled drives are intended for PowerEdge servers and PowerVault arrays with 3.5-inch SATA bays. Most server RAID controllers accept SATA drives, as do plain SATA ports. The part number 8JYD7 is the reliable reference when checking this drive against your system.

Condition is certified refurbished, and each drive is inspected, bench-tested and wiped in Johannesburg.
