Dell TX8WW 4 TB SAS drive

The Dell TX8WW is a 3.5 inch internal hard drive built for desktop systems and servers that accept SAS connections. It delivers 4 TB of storage on a 7200 RPM spindle for nearline workloads.

SAS 12 Gb/s interface

The single specification that determines compatibility is the 12 Gb/s SAS interface; the drive will only operate in controllers or backplanes that support this exact protocol and speed.

Hot-swap tray included

A hot-swap tray ships with the bare drive so it can be inserted or removed from compatible bays without powering down the chassis. This tray is the only bundled hardware; no cables, screws or software are supplied.
