Western Digital WD2003FYYS-02W0B1 2TB 7200 RPM 64MB SATA 3.0Gb/s 3.5" internal hard drive

2TB RE4 enterprise drive

The Western Digital WD2003FYYS-02W0B1 is a 3.5-inch internal hard drive built for continuous operation in servers and surveillance arrays. It delivers 2TB of storage on a SATA 3.0Gb/s interface, spins at 7200 RPM and carries a 64MB cache to sustain heavy write workloads.

Write-intensive workloads, not boot speed

This drive suits administrators who need reliable capacity for recording multiple camera streams or logging database transactions around the clock. It is not designed for low-latency boot or application drives where solid-state storage would provide a markedly different experience.

SATA 3.0Gb/s interface

The drive connects through a standard SATA 3.0Gb/s port, so the host system must provide that exact interface. Builders using newer SATA 6.0Gb/s controllers should verify backward compatibility before purchase.
