Not intended as a threadcrap, but I really fail to understand the "excitement" surrounding this drive. Take away the marketing hype and novelty of a 10K SATA drive, you have very little to justify the price or the product itself. You have to ask the question...what problem or market need does this address?
If you are in an enterprise server environment, bring out the SCSI hardware and get on with it. Yeah, SCSI is expensive, but you are dealing with mission critical applications which demand speed and reliability. Forgive the condescending tone, but only the naive and uneducated would consider this drive as a viable option. It is really a joke.
For the desktop market, the current crop of 7200RPM drives, especially those with 8MB caches are more that adequate. I doubt you would notice the difference in actual use between this drive and the better 7200RPM drives, except in your pocket book.
Another point to consider is the value of "real estate" in your computer. Ask yourself, are you willing to give up an open drive bay for 36GB??? I have 40GB drives sitting on the shelf. The smallest capacity I would even condider purchasing today is an 80GB 7200RPM but only if it has 8MB cache and dirt cheap. In truth, 120GB seem to be the ideal balance of capacity, performance and price for this market, especially when they can be found for $80 or less, after rebates.
The only area that I can see that this drive might provide any meaningful benefit would be for video editing on an entry level workstation. Even then, most knowledgeable users would still gravitate to SCSI. Even then, I don't believe it should command a premium of perhaps 10-15% over equivalent 7200RPM drives.
I'll sit this one out.
