Toshiba MG04 4TB 7.2K SAS 12G LFF 512e Hard Drive
MG04SCA40EE · Refurbished · 1 year warranty
Two features set the MG04SCA40EE apart from a basic nearline disk: dual-port SAS and persistent write cache. The persistent write cache protects data held in cache if power is lost, and the dual-port design gives two paths to the drive for redundant controllers.
Capacity is 4TB on a 3.5in LFF form factor. The drive spins at 7200 RPM and runs SAS at 12Gb/s. It uses 512e sectors (4K physical sectors with 512-byte emulation), with 128MB of cache and a sustained transfer rate of 205 MiB/s.
Toshiba rates this MG04 model for 550 TB per year of workload and an MTTF of 1,400,000 hours. Maximum power draw is 11.8 W.
It suits servers, JBODs and storage arrays that need 4TB SAS drives in 3.5in bays. New and Refurbished drives come with 1 year or 3 years of warranty; Used drives have 90 days.
