3TB Enterprise Nearline Drive

The Western Digital WD3000FYYZ is a 3.5-inch SATA hard drive built for 24x7 enterprise workloads. Its 7200 RPM spindle and 64MB cache serve business-critical applications that demand sustained throughput. The RE series targets storage arrays and servers where capacity and reliability outweigh raw speed.

SATA 6.0Gb/s Interface Limits

The drive connects through a standard SATA 6.0Gb/s port, capping the theoretical bus at 6.0Gb/s. Sequential transfers reach up to 171MB/s in practice, so the interface does not bottleneck the mechanical media. Random I/O performance scales with the dual-processor architecture, yet the SATA link remains the hard ceiling for burst traffic.

1.2 Million Hour MTBF Build

A 1.2 million hour MTBF rating and 100% duty-cycle design signal readiness for continuous operation. Enhanced RAFF technology counters linear and rotational vibration in real time, preserving performance inside dense multi-drive chassis. The bare-drive packaging and 26.10mm height fit standard 3.5-inch bays without adapters.

Questions about this item

Should I choose the 3TB RE drive or a smaller capacity for my RAID array?

The RE series spans 2TB to 4TB; the 3TB model gives a balance of capacity and the 171MB/s sustained rate with 1.2M-hour MTBF for 24x7 RAID duty.

What does the 171MB/s sustained rate mean when the drive is installed in a server?

It is the maximum sequential throughput the platters can deliver under typical enterprise workloads, so large-file streaming will approach that figure while random I/O will be lower.

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

The 6.0Gb/s link supports the drive's 171MB/s sustained speed and 64MB cache bursts without bottlenecking the mechanical media.
