Look at its statistics: 10K RPM, 300GB (279.5GB formatted), 1.4 Million Hour MTBF Enterprise reliability factor, 3-platter internal configuration, Icy Dock Heat-Sink/2.5" to 3.5" Adapter, Back-Plane ready, 16MB Cache...and best of all to go along with that 1.4 Million MTBF (mean time before failure) rating it's guaranteed to last 5-years by Western Digital's all-inclusive Factory Warranty, the highest in the business. I'm a big fan of WD's Enterprise HD's, and use them extensively when building systems, or equipping my own system for ultimate reliability and performance. The "new generation" of VelociRaptor HD's is not only faster in all respects than Gen. No.1, its builders have tried very hard to make certain that reliability goes hand-in-hand with high performance, apparently. You can't say enough about attention to detail here either, with that very cool Icy Dock heat-sink/2.5" to 3.5" carrier mounting system either. A lot of people don't realize that these HD's are in reality just 2.5" in size, truly a little dog doing a big dog's work! So getting 10K RPM performance out of a little 2.5" form-factor system is truly interesting to me, and I have a bit of respect for Western Digital engineering for pulling this out of the hat and making them better 2nd time around, all-around. Let me give you some statistics from HD Tune Pro's benchmarks, and we'll see how a fully loaded and empty Raptor 300GB performs, and perhaps that will shed some light on just how good the HD's are overall. Fresh formatted and empty, I tested my Raptor in my brand new OEM PC (home built, totally 100% custom-made with all high-end hand-picked parts) with HD Tune Pro, and got this kind of performance: 1) from 8KB to 8192KB block size, with 64MB file size, it *averaged* 128MB/sec Read Speed and 142MB/sec Write Speed 2) same test, loaded with Vista Ultimate 64-bit OS, and some 70GB worth of key applications and a base system of samples and key photographs for my imaging business, making it 72% open space, it *averaged* 97MB/sec Read Speed and 104MB/sec Write Speed 3) In the Benchmark Test, again loaded with the OS and applications and samples, we get 121MB/sec maximum Read Speed, 68MB/sec minimum Read Speed for an average of 101MB/sec across the volume from 0% full to 100% full, a very linear performance. 4) Benchmark Test, loaded, access time is a whopping 7.3 milliseconds (ms), Burst Rate is 152MB/sec., both range-topping figures from any platter HD I've ever tested! That kind of performance is what makes people so happy to spend $240 or so on this HD in bulk form, more than $300 in retail boxes, and I cannot argue with their logic after installing and using a Raptor for my boot HD in the new PC build. I've got every new trick in the business in this PC, including the newest, latest, and greatest EVGA X58 1366-compatible motherboard, and twin companion WD "Black" 1TB HD's in an internal 2TB RAID "0" write/read-to volume, plus a big 4TB external RAID 6 system for movies and film, audio, and countless other high-GB-sized projects that I do, and the Raptor controls all of it tight, clean, fast, and reliably. With all of that menage' internally and externally in this PC, boot time would be several minutes normally, but the Raptor puts everything necessary loaded up and ready in less than a minute. I've trimmed the Start-Up Items to just 23 totally necessary things, where most people wouldn't bother, and that helps with boot time incredibly, or load-time when doing a restart after installing an application or one-time venture for a project, but that is a very, very quick start-up, and you have to give it to the Raptor for pulling it off. In addition, the Icy Dock seems to do wonders for keeping the Raptor literally cool temperature-wise, as I've never seen temps
