The 10K RPM drive will have a smaller rotational latency due....

The faster spin means that there will be a very small difference in the length and so be read faster... .
Decent 7200rpm hard drive can push out 40-80Megabyte/sec for sequential reads, so even though your RAID and 5400 RPM drives.

I need an internal HDD for storage/media etc (I have an SSD for the OS) to replace my Seagate; I do need 1 TB, but not more. The biggest program I'd use it for is Adobe Photoshop CS4.
So looks like the main differentiating features are RPM (5400/5900/...
