“…the fastest 7,200 RPM hard disk we’ve seen in our test labs to date.”

– Tom’s Hardware1

After extensive drive testing, Tom’s Hardware proclaims, “With peak data rates up to 95 MB/s, the 750 GB top-of-the-line member in the

Caviar SE16 family is the fastest 7,200 RPM hard disk we’ve seen in our test labs to date.” The review continues, “…our benchmarks should give

WD plenty to cheer about. In particular, the I/O performance in the file server and database server schemas is noticeably superior to that of other

7,200 RPM drives.” (As evidenced by the graphs above.)

The WD Caviar SE16 has the industry buzzing.

“The benchmarks speak for themselves: Western Digital

took the winning Caviar SE16 formula, added

perpendicular recording, and created a huge, yet speedy

7200RPM hard drive in the form of the WD7500AAKS.”

“Overall, none of the other drives could touch the

WD7500AAKS in our benchmarks.”

HotHardware2August 2007

“The Western Digital WD7500AAKS offers strong

performance, runs quietly, and emits relatively low amounts

of heat.”

“This drive is an example that shines above its

750GB brethren.” AnandTech3August 2007

“Blazing fast”

“750 GB, 16 MB cache, and great performance all for less

than a buck per 3 GB make this drive deserving of our

Editor’s Choice Award.” MikhailTech4July 2007

Technology Features

Perpendicular Magnetic Recording (PMR) — The latest

generation of WD Caviar SE16 drives employs PMR

technology to achieve even greater areal density.

IntelliSeek — Calculates optimum seek speeds to lower power

consumption, noise, and vibration.

SecurePark — Parks the recording heads off the disk surface

during spin up, spin down and when the drive is off, resulting in

improved long term reliability.

StableTrac — Secures the motor shaft at both ends to reduce

system-induced vibration and stabilize platters for accurate

tracking during read and write operations.
