“…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.
