Summary: This drive caught my eye because of the 5 year warranty, and the 10k rpm. I find the price completely reasonable for a drive with these specs. Although, like others here, I didn't do a before and after performance test, I did notice a difference in program load and file save times.
Summary: This is a fantastic storage and performance grade hard drive that I've owned for some time. I first had the original Velicoraptor 300Gb (before the SATA revision layout change)and I've picked up several of these drives to use for performance hard-drives.
Pros: Best consumer grade and entry-level enterprise 3.5" hard drive
Summary: I just ordered 2 of them. I always used Raptors for my Raid 0 Array. I wouldn't consider anything else for the price & reliability. I know fast & large capacity SSD's are still too expensive & you need to be careful how you treat them.
Summary: i installed a pair of these in a raid set, they come close to loading speed of the ssd's i have tested, without the ssd's data loss problems, my only gripe is the huge heatsink, you cannot remove it to use these in a laptop without voiding the warranty..
