but why not? for 300 dollars I can raid two much larger harddrives and probably break even with the one velociraptor
Break even in a sequential read test maybe. But not access time or cpu%. And most times, access time is where it's at (well os chores and gaming atleast). How often do we need to sequentially read hundred's of mb for that one test to even matter? If you need more space, and dependant on how much money you have, sure 2 larger drives may be better. I'd take a velociraptor and it's scrawny 16mb cache over 2 larger drives in raid-0 with 64mb combined cache any day.
Doing a search of raid-0 vs velociraptor, I found the following results. It has 2 150x's in raid-0 and 2 of the faster wd640's in raid-0 vs velociraptor, in several tests. Once you load this page, you can go to the tests previous page and see that the read and writes are similar, and the access time as I stated above, but I like the pc tests since they are more real world usage type.
