Dell 4 TB SATA desktop drive

This 3.5 inch internal hard drive delivers 4000 GB of storage on a SATA 6 Gb/s interface. It spins at 7200 RPM and is supplied new in retail or OEM packaging. The drive suits desktop PCs and entry-level servers that need high-capacity mechanical storage.

Capacity and headroom

Four terabytes hold large media libraries, backups and archival data with room to spare. Sequential throughput is limited by the 7200 RPM platters and SATA link, so sustained transfers top out well below SSD speeds. Random I/O workloads such as databases or virtual machines will hit latency limits quickly. Buyers who need faster access or lower latency should consider solid-state alternatives.
