Hitachi GST has announced a 900GB small form-factor drive, thus catching up with Seagate's Savvio. The Ultrastar C10K900 is a 3-platter, 2.5-inch enterprise-grade 6Gbit/s SAS drive that spins at 10,000rpm and holds 0.9TB of data - 300GB more than the C10K600. Hitachi says average seek times are as low as 3.8ms, and has a "random …
That's an impressive spec. How long before the standard desktop PC drive becomes 2.5in and the 3.5in format dies out for anything smaller than a Terabyte or two?

Will depend on the drive cost, but 2.5 format has an intrinsic advantage because it's lighter, less raw material and lower shipping cost. Days when 2.5in always meant smaller capacity or slower than 3.5in (or both) are clearly gone.
Yes, I know this one is an enterprise drive. I'm looking ahead ... anything in the Enterprise market today will be on the desktop of tomorrow.
