Overview
Western Digital MegaScale 4000 HMS5C4040ALE640 is a 4TB hard drive in the 3.5in LFF size. It spins at 5700 rpm and connects over SATA at 6 Gb/s, with a 64MB cache and 512e sector format.
The lower spindle speed keeps power down: idle power is rated at 4.9W. Sustained transfer is 138 MB/s, and the drive is rated for 600,000 load/unload cycles. It weighs 690 g. Those numbers fit bulk storage, backup and archive, where many drives run for long periods and capacity per watt matters more than speed.
The 512e format uses 4K physical sectors that present as 512-byte logical sectors, so check that your system and operating system handle 512e drives.
This drive is available New or Refurbished. Both come with a choice of 1 year or 3 years of warranty.
