Dell WD3200AAKS 320 GB SATA desktop drive

This 3.5 inch internal hard drive delivers 320 GB of storage on a SATA 3 Gb/s interface. It spins at 7200 RPM and includes a 16 MB cache. The drive is supplied new and ready for desktop installation.

Suits desktop PCs needing a 320 GB mechanical drive

Buyers who want more storage, faster transfer rates or a solid-state alternative should look elsewhere. The 3 Gb/s SATA link and 16 MB buffer limit throughput for demanding workloads. Laptop or small-form-factor systems requiring a 2.5 inch drive cannot use this unit.

SATA 3 Gb/s interface decides compatibility

The drive connects only to a standard SATA port on a desktop motherboard or controller. Verify that the system provides a 3.5 inch bay and a matching data cable before purchase.

Questions about this item

How much data can the 16 MB cache buffer absorb before the 7200 RPM platters become the bottleneck during sustained writes?

The 16 MB buffer caches incoming bursts, but once it fills the drive is limited by the 7200 RPM mechanical throughput.

What noise and heat levels should I expect from the 3.5 inch SATA mechanism running continuously in a desktop chassis?

WhisperDrive and SoftSeek technologies reduce acoustic output, while the 2.0 pound 3.5 inch form factor dissipates heat through the drive bay.

Which host connector and power lead must my motherboard and PSU already provide for this 3 Gb/s SATA drive to operate?

A standard SATA data port and a SATA power connector from the power supply are required.
