Dell 12TB 3.5-inch 7.2K SATA 6Gbps Hard Drive — 753F0

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 753F0 (Toshiba manufactured), maker model MG07ACA12TEY.

Hot-plug bays let a failed member of a redundant array be replaced without powering the server down. A drive needs the tray or caddy that matches the server generation to sit in a hot-plug bay. Keeping a spare drive per array shortens the time an array runs degraded after a failure. After a swap the controller rebuilds the data onto the new drive; the bigger the drive, the longer that takes. Dell-labelled drives are intended for PowerEdge servers and PowerVault arrays with 3.5-inch SATA bays. It uses 512e sectors (4K physical, 512-byte emulated), which current RAID controllers and operating systems handle natively. Capacity-class disks like this are the usual building block for backup repositories, video archives and large file shares. When replacing a failed disk, match the capacity, speed and interface of the drives already in the array. The part number 753F0 is the reliable reference when checking this drive against your system.

As a certified refurbished drive, it is inspected, bench-tested and data-wiped by our Johannesburg team before release.
