Enterprise Nearline Storage

The Western Digital WD1003FBYZ is a 1TB 3.5-inch SATA 6.0Gb/s hard drive built for enterprise servers and storage arrays. It spins at 7200 RPM with a 64MB cache to support write-intensive workloads such as video surveillance and business-critical applications.

Suited for Always-On Workloads

This drive targets administrators who need high-capacity nearline storage for daily computing in rackmount or tower servers. Buyers who want more capacity, a smaller form factor, or a solid-state interface should consider other options.

SATA 6.0Gb/s Interface Decides Fit

The single specification that determines compatibility is the SATA 6.0Gb/s interface; the system must provide a matching port and power connector. Average seek time is 8.9ms and the drive measures 147.00mm long, 101.60mm wide, and 26.10mm high.

Questions about this item

What capacity does the WD1003FBYZ offer and is it the only size available?

This specific model provides 1TB of storage; other capacities exist in the RE series but are separate model numbers.

What does the 7200 RPM rating mean for everyday workloads?

The 7200 RPM spindle delivers an 8.9 ms average seek time and 64 MB cache, giving responsive performance for write-intensive tasks such as video surveillance or enterprise storage.

How does the SATA 6.0Gb/s interface affect real-world throughput?

The SATA 6.0Gb/s link caps the burst transfer rate at 6 Gb/s; sustained speeds are governed by the mechanical 7200 RPM platters and 8.9 ms seek time.
