HGST 0F14688 4 TB 7200 RPM SATA 3.5" internal hard drive

4 TB enterprise drive for desktop storage

This 3.5-inch internal hard drive delivers 4 TB of capacity on a SATA 600 interface. It spins at 7200 RPM with a 64 MB buffer for sustained throughput. The Ultrastar 7K4000 design targets always-on workloads in desktop chassis. It suits users who need large, reliable bulk storage for media archives or backups.

SATA 600 interface limits peak transfer to 600 MB/s

The drive connects through a standard SATA port capped at 600 MB/s by the specification. Real-world sequential speeds will sit below this ceiling due to mechanical latency. Random I/O performance is constrained by the 7200 RPM spindle speed. Builders needing higher IOPS or lower latency should consider solid-state alternatives.

7200 RPM spindle speed defines responsiveness

The 7200 RPM rotation rate sets the baseline for access time and sustained transfer rates. Faster spindles would improve latency but increase power draw and noise. Slower spindles would reduce performance for active workloads. Choose this drive when 7200 RPM matches the required balance of speed, capacity and cost.
