3TB 7200 RPM SAS Enterprise Drive

The Western Digital WD3001FYYG is a 3.5-inch internal hard drive built for enterprise storage systems. It operates at 7200 RPM with a SAS 6Gb/s interface and 32MB cache. The drive is rated for 24x7 operation at 100% duty cycle with a 1.4 million hour MTBF. It is supplied as a bare drive in new condition.

Suited for Nearline Arrays, Not Desktop PCs

This drive fits servers and external arrays that need high-capacity nearline storage with dual-port SAS connectivity. It supports full internal error detection and correction for data integrity. Buyers without a SAS host bus adapter or RAID controller cannot use this drive. It is not intended for consumer desktop motherboards or external enclosures lacking SAS ports.

SAS 6Gb/s Interface Determines Host Compatibility

The drive requires a controller or backplane with native SAS 6Gb/s ports to operate. Dual-port, full-duplex connectivity eliminates single points of failure in enterprise topologies. Sustained sequential data rates reach 182MB/s for business-critical workloads. Verify your system supports SAS before purchasing.

Questions about this item

Will the 3.5-inch form factor fit my standard drive bay?

The 3.5-inch form factor matches standard internal bays, so it mounts directly without adapters.

How do I connect the SAS 6Gb/s interface and what step is often missed?

Attach the SAS cable to the dual-port connector and ensure both ports are seated for full duplex operation.

When should I plan to replace this drive in a 24x7 server?

The 1.4 million hour MTBF rating supports continuous 100% duty cycle operation for years before replacement.
