Dell 1TB SATA desktop drive

This new Dell drive delivers one terabyte of storage on a 3.5-inch form factor using a SATA 6.0Gb/s interface. It spins at 7200 RPM and uses 512n sector formatting for broad compatibility with desktop systems and entry-level servers. The unit ships in retail or OEM packaging that may vary.

Practical limits of the SATA interface

Sequential throughput is capped by the 6.0Gb/s link, so sustained reads and writes cannot exceed that ceiling regardless of the drive’s internal speed. Random I/O performance is constrained by the 7200 RPM rotational latency, making the drive less suited for workloads that demand low-latency access to many small files. Builders who need higher throughput or lower latency should consider drives that use faster interfaces. Buyers who require more capacity than one terabyte will need additional or larger drives.

Questions about this item

How do I decide between the 1TB model and other capacities?

This listing is for the 1TB capacity only; if you need more space you would have to choose a different drive with a larger capacity.

What does the 7200 RPM rating mean for everyday use?

The 7200 RPM spindle provides quicker data access than slower-spinning drives, reducing load times for the operating system and applications.
