Dell 16TB 3.5-inch 7.2K SAS 12Gbps Hard Drive — 4N7V0

A 16TB SAS hard drive in the 3.5-inch form factor spinning at 7.2K rpm over a 12Gbps SAS link, supplied under Dell part number 4N7V0 and built on a Toshiba drive, maker model MG08SCA16TEY.

Dell part numbers identify the exact revision, which matters more than the description when several look-alike parts exist. As a Dell-labelled drive it carries Dell firmware, matching what PowerEdge servers and PowerVault arrays are set up to use. Dell-labelled drives are intended for PowerEdge servers and PowerVault arrays with 3.5-inch SAS bays. 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. The part number 4N7V0 is the reliable reference when checking this drive against your system.

Sold as certified refurbished, the drive passes inspection and a bench test, and has its storage wiped, in Johannesburg before release.
