Enterprise SATA drive for write-heavy workloads
The WD RE4 WD1003FBYX is a 1TB 3.5-inch internal hard drive built for servers, video surveillance and other demanding write-intensive applications. It spins at 7200 RPM with 64MB cache and uses the SATA 3.0Gb/s interface.
SATA 3.0Gb/s caps sustained throughput
The interface tops out at 3.0Gb/s, so sequential read and write speeds cannot exceed that ceiling regardless of the drive’s 7200 RPM spindle speed. Random I/O performance is also bounded by the same link and the 64MB cache buffer.
Enterprise build with vibration tolerance
Fourth-generation vibration tolerance helps maintain consistent operation in multi-drive chassis where adjacent spindles create rotational disturbance. Standard 3.5-inch mounting and SATA connectors allow direct installation in server backplanes or desktop bays without adapters.
