i picked up a vr the other day to add some speed to my system...at the same time, i grabbed a WD caviar black 1tb for storage.
after hooking them up, and getting my os installed..i compared speeds of the new drive with the OS and other stuff loaded to the empty 1tb drive and to my old seagate 500gb..
the seagate was horrible...but the 1tb drive was only a couple steps behind my VR.
seagate was around 70

here is the score for the caviar black 1tb using xbench (on a osx86 system right now so i dont have many options..if anyone can recommend something for HD testing on a mac..let me know)

i ran this test on the single VR and it scored a 105.something
i dont have the info right now, i currently have the drive configured in a RAID and cant test it at the moment)
i was expecting a bit bigger difference than this..especially for the smaller capacity..and the HUGE price difference.

so then after some readin online, i became interested in setting up a software RAID 0 stripe using apple raid (128k stripe) built into osx...people were having excellent results even compared to hardware raid..
i set this up..everything went smoothly..and the tested results from the 2 x VR RAID 0 :

now i was somewhat pleased with this result
...until i read some results from others in the same thread where the apple RAID discussion was taking place..
the person who posted the thread had taken two samsung spinpoint 1tb drives and scored a 194 on their disk test.
so i set up an apple raid with 2 different HDDs, a 1tb and a 500gb seagate..slower drives..supposedly.

(sorry..got these from an online score i posted..the formatting is messed up)

the results are only a couple steps behind the $400+ VR raid setup!

i was wondering if i am waisting my money on these VR drives...and should i just order the cheaper samsung drives and have a faster setup with MUCH more storage? i can get the samsung drives for under 100.
these VRs are alot of hype in my book...im going to package them up after a couple spinpoints are in my hands....
if anyone has any help or advice to offer...thats why im here!

the installs are all clones of eachother..so they dont differ at all..

i dont understand how the apple raid could be limiting it, considering many others have gotten much better results using the same apple raid and slower drives...
im just not too impressed with these drives considering the rip off price..
RAID 0 with some caviars or spinpoints beats the hell outta the VRs in a raid

after continually being unimpressed by these velociraptors..i just took one of them back and am about to package up the other one since i just ordered a couple 640mb aals that should be here in a couple days...i figure RAID 0 performance with those will be close to the VR drives...'

OK, so i returned both of the velociraptors...
and my two 640gb AALS drives came in..

yes, i have a ich10r congroller...but when i was using these for the apple drive..it wasnt a hardware raid, it was just using a software config.

NOW...i have the two AALS's in a RAID 0 stripe using hardware, ich10r...installed vista on it last night.

i need to figure out how to get my old vista HD to boot up now that I have converted to raid mode (ahci)...i read online there is a way to get it to work.
once that is done..i assume there are utilities to let me clone my current vista install onto the new RAID array..correct?

woudl it be smarter to reinstall vista on the new RAID drive...or could I just clone the old install onto this new drive and it would work?

thanks for the help..
once i get it all installed, i will download some benchmarks so i can see how the raid drive is performing.
im expecting that this hardware raid 0 with the aals will be close or better than the software RAID with the velociraptors.

thanks for any help and suggestions!
