What this drive is
This Western Digital Caviar GP WD7500AACS is a 750GB 3.5-inch internal hard drive with a SATA 3.0Gb/s interface. It uses IntelliPower technology to vary spindle speed between 5400 and 7200 RPM and includes a 16MB cache. The drive is designed for low power storage in desktop systems.
Who this suits
It suits users adding secondary storage for backups, media libraries or archival data where low power draw and quiet operation matter more than peak throughput. Builders needing a fixed 7200 RPM spindle speed, larger cache, or higher sequential transfer rates for primary application drives should consider other options.
Deciding specification
The variable 5400 to 7200 RPM spindle speed is the single specification that determines suitability. It delivers reduced power consumption and heat at the cost of consistent rotational latency. Verify that your workload tolerates variable seek performance before choosing this drive.

Perguntas sobre este artigo
How much power and heat does the IntelliPower 5400 to 7200 RPM drive produce when running continuously?
IntelliPower balances spin speed, transfer rate and cache to deliver significant power savings and solid performance for low power storage.
What host interface must my desktop already provide for this 3.5 inch SATA 3.0Gb/s bare drive?
The drive requires a standard SATA 3.0Gb/s port and a 3.5 inch drive bay with matching power and data cables.
Will the 8.9ms average seek time and 16MB cache work well with older SATA 1.5Gb/s controllers?
The SATA 3.0Gb/s interface is backward compatible, so the drive will operate on older SATA controllers at their supported speed.
