Western Digital SE16 750GB: "Quiet" a Performer

HD Tune / HD Tach
In HD Tune 2.53, the Western Digital drive turns in an average sustained transfer rate of 73.0MB/s, which measures up very well against its peers. In our labs, this has been the fastest result we've recorded to date - very encouraging indeed! The 13.2ms access time reported by HD Tune is merely adequate, landing squarely within the ranks of its peers.
HD Tach clocks the sequential read speed of the 7500AAKS at an average rate of 77.1MB/s, a score again puts the WD7500AAKS above its peers. The Seagate 7200.10 750GB drive, for example, scores 66.9MB/s. The WD7500AAKS even beats the 150GB Western Digital Raptor in this test by nearly 2MB/second, which is no mean feat.
However, it is important to note that access times, average read rates, and burst rate measurements are basically synthetic measurements, and while important these are not "true" application measurements. There is a great deal of potential bottlenecks elsewhere in the system that can and will affect the true performance of a drive. Although these "benchmarks" are a good indicator of a drive's performance, it is the total make-up of components in the PC that will determine the drive's actual performance.

for Samsung to offer larger drivesLord Evermore - Thursday, August 9, 2007 - link
So...have all drives up to this point only had the drive shaft secured on one side? The end of the shaft just spinning in the air between the top platter and the casing? That seems like a very unlikely thing given how easily that could result in the platters moving and hitting the heads or even hitting the casing. Given the G forces they're rated to handle even when running makes it sound even less likely.Lord Evermore - Thursday, August 9, 2007 - link
Oh, and haven't all drives had auto-parking heads for like a decade or more? The only reason the heads would move onto the platter during spin-up is if the controller specifically drives the armature to do so. So basically, SecurePark is WD saying "hey, we don't do something stupid with the heads anymore!"I hate how every company has to give their own trademarked name to a basic technology that everybody has.

I've noticed in stores 250, 320 and 400GB versions of AAKS are they the same revision drives? I'm ready to order one if so.Also, with the same capacities WD has drives in series KS.
Please, I need support, I'm buying a new PC. Thank you

Where did you find the Seagate for 180?Gary Key - Thursday, August 9, 2007 - link
At the time Dave wrote this, our price engine was showing ClubIT to have it for $188.89 if I remember right. I just checked and it was up to $199. We will get the article updated shortly.AdamK47 - Thursday, August 9, 2007 - link
