750 GB desktop hard drive

This 3.5 inch SATA hard drive delivers 750 GB of storage for desktop computers. It spins at 7200 RPM with a 32 MB cache and a 6 Gb/s interface. The drive is sold new as a bare unit without cables or brackets. It suits users adding primary or secondary storage to a standard PC.

Shock Guard and NoTouch Ramp Load technologies

Shock Guard Technology protects the drive mechanics from impact during handling or operation. IntelliSeek Technology optimises seek speeds to lower power consumption and noise. NoTouch Ramp Load Technology keeps the recording head off the disk surface during start, stop and park cycles to reduce wear.

750 GB capacity with 7200 RPM performance

The 750 GB capacity holds operating systems, applications and large media libraries with room for growth. Sustained 7200 RPM speed supports smooth file transfers and responsive application loads. The 32 MB buffer helps absorb burst workloads. Very large media archives or multi-terabyte backup sets will exceed the available space.

Questions about this item

Will the 32MB cache need any firmware update or replacement over the drive's life?

The 32MB cache is built into the drive controller and requires no separate maintenance or replacement.

Does the 7200RPM spindle speed become the throughput bottleneck during long sequential transfers?

Sustained transfer rates are limited by the 7200RPM rotational speed and the SATA 6Gb/s interface.

How much heat and noise does the 3.5" 7200RPM mechanism produce when running continuously?

The 7200RPM motor and IntelliSeek technology generate typical desktop-drive heat and audible seek noise under all-day operation.
