RAID-0 vs. 10k RPM drives

[avi85]

My biggest bottleneck by far is my HD an I was wondering what would give me a bigger performance boost and by how much (links anyone?)

TIA

you might wanna check out http://storagereview.com
gives benchmarks of pretty much every drive out including 10k raptors and i believe there are a few raid benchmarks on there

basically raid0 won't help with much else cept yur sustained transfer speeds tho so don't expect seek times or anything dealing with many small files to benefit too substantially

those drives you list are already pretty fast
i can say i am happy with the speed of my single 74GB 10k raptor it was a big step up from the 80GB 7200rpm wd i had
i have 2 320GB 16MB wd drives coming in tomarrow that i plan to put in raid1 (cause i already feel the speed will be plenty for me for storage)

also take into account that if you do got raid0 with a pci controller you are gonna be limited by the ~120MB/s or so that the pci bus will be able to give you whcih is basically 2 7200rpm drives in raid0

what exactely are you running that requires more speed ?

Here is another thread on the same subject at tomshardware forums
i noticed it had a few links that could help you
good luck

do a search on 10k vs 7200rpm ..

The obvious answer is 10k RPM raid 0 setup

Or 15K U320 SCSI Radi 0

Look into getting an SAS (serial attached scsi) enclosure from adaptec and a SAS controller card (unfortunatly these run around $700 still.) Then stuff the enclosure full of 500GB SATA II 7200 RPM drives. You can do SAS drives but the SATAII should do you fine. You'll get twice the IO of 320 scsi and all the benifits of raid 5 or 1+0 for a thrid of the price.

If you need it I would look at the Adaptec Snap 500 or 550 servers. Yum.
