Any benefit to a Raptor 10000rpm for Sage?

[btrcp2000]

I want to add a second HDD to image my primary OS/Sage drive. In the process of looking for a good deal, I ran across the WD Raptor for $84. More than I would spend normally for a 7200rpm drive, but is there any benefit to this as the system drive for sage, and then using my old drive for the image backup? My files will remain on a separate 500 gigger at 7200rpm.

Nope, Sage doesn't do the sort of random IO that would benefit from a 10k drive.

I run sagetv 6 on 2 raptors in raid 0. 3 people are watching recordings so I guess it works better.

Better than what? Were you having trouble with a single drive? I wouldn't expect a RAID-0 array of raptors to have trouble with 3 recordings/viewings. But I also wouldn't expect a single 7200rpm drive to have any trouble either.

Raptors have better access times, so they're best as an OS/swap disk. However, the platter densities aren't even close to current 7200rpm drives, so their sustained read/write performance suffers. For recording, you're better off with larger 7200rpm drives.

10K RPM would have a bit faster transfer speed. But SATA II is plenty fast at 7200RPM.
