4 TB 7 200 RPM SATA desktop drive

This 3.5 inch SATA hard drive provides four terabytes of storage on a 7 200 RPM spindle with a 64 MB cache. It is built for desktop workstations and entry-level servers that need high-capacity bulk storage. The drive ships new and includes an R Series caddy for tool-less mounting in compatible bays.

Compatibility checklist for your system

Verify that your motherboard or controller offers a free SATA 6 Gb/s port and that the chassis has an open 3.5 inch bay with the correct mounting points for the included tray. Confirm the power supply has an available SATA power connector for the drive. No additional drivers are required for standard SATA operation.

Upgrade path from smaller or slower drives

Replacing a lower-capacity 7 200 RPM drive or a 5 400 RPM model with this unit adds both space and sustained throughput for large-file workloads. The jump is worthwhile when current volumes are near capacity or when sequential read and write speeds become a bottleneck for backups, media libraries or archival tasks.
