Product identity
This Western Digital WD RE4 desktop hard drive delivers 500 GB of storage on a 3.5 inch form factor with a SATA 3.0Gb/s interface. The 7200 RPM spindle speed and 64 MB cache support consistent throughput for RAID arrays and always-on workloads.
Who it suits
It suits system builders populating multi-bay enclosures or servers that require 24x7 reliability and a 1.2 million hour MTBF rating. Buyers needing solid-state speed, larger capacities or a SATA 6.0Gb/s interface should consider other options.
Deciding specification
The SATA 3.0Gb/s interface is the single specification that determines whether this drive matches your controller or backplane. Verify that your host bus adapter or motherboard port operates at this generation before purchasing.

Questions about this item

Which step is often missed when installing this bare RE4 drive in a desktop?
Many builders forget to secure the drive with four 3.5-inch mounting screws, leaving it loose in the bay.
