Which would be faster: 2xRAID0 or 1x10K rpm?

[nking]

Which setup would be faster: 2 7200 rpm hard drives in a RAID0 array, or a 10,000 RPM Western Digital VelociRaptor drive?

Thanks

the raid 0 would be faster assuming sata modern drives

Don't raid your OS drive if you aren't ok with reinstalling/losing everything when the stripe fails.

How common is it that the stripe fails?

Common enough to warrant keeping a image of your setup handy. I've had maybe 2 failures in 3 years.

But I believe that the single velociraptor will be faster then the 2 7200 rpm drives. Benches have shown that a single velociraptor is as fast as 2 of the older 10k raptors in a raid 0. But you definately won't be getting a lot of storage for your money.

a couple of drives to your description "2 7200 rpm drives" includes IDE, SATA and SCSI drives from the last 10 years or so. check the performance of the drives you would otherwise stripe then compare that to a velociraptor.

Something you should consider is that the 7200.11 drivers are generally faster than the 74 and 150 gb raptors. The 640GB one from Western Digital is a very good choice, model name is WD6400AAKS. It's cheap and huge too, only a bit slower than the 300gb velociraptor, faster than the older ones.

RAID 0 does fail often though, and provides absolutely no gains in gaming. I'd advise against it unless you absolutely need the little extra speed.

my raid 0 never faild, so i say, go for it. tons of programs can do undelete from a broken raid0 (for ex. active@ file recovery), so don't vorry if something bad is happening.
raid0 rocks

It depends what you are looking for, A velociraptor would be faster for games as the access speeds just are faster then any 7.200 in raid-0 but if you work with large files a raid-0 setup would be faster. That said a 7200 raid-0 set up would be faster than a normal (old) raptor but not faster then the new velciraptor.

Alright thanks everyone I think I'm gonna use 2x7200.11 WD drives in RAID0.
