Please test your RAID 0 with this....

[Wam7]

Can those with RAID 0 arrays test their speeds with this program http://www.wam77.pwp.blueyonder.co.uk/RaptorTest.rar and post what speeds they get. It a small program from Canopus to test whether hard drives are up to video editing speeds.

Please state 1) which controller you use, 2) how full your drives are (as this effects speed), 3) stripe size, 4) the make and size of drives.

I should add only give the result for the first time you run it as the cache kicks in for subsequent runs.

1) Via VT6410 on AsusP4P800 Dlx
2)40% full
3)64K stripe
4)2x 120gig Hitachi 7K250

Call me a lumox flame all you want but how do you use this?

 

[Wam7]

Download/Extract and run the Raptest.exe. Only give the result for the first time you run it as the cache kicks in for subsequent runs

It didnt save the read/write test in the text though. Thats a shame. And it detected XP Pro as Win2000, funny.

Do my speeds seem slow? I have 2 36gb raptors in RAID 0, and I'm getting only 43mb read, 66mb write. I have defragged, and did a fresh reboot before running the test. No other programs are accessing the drives during the test, and my antivirus is disabled.

Here's a fun one I tried during some downtime at work:

1. LSI 22320-R Ultra320 SCSI controller
2. Empty "drives" (about 800MB total space)
3. 64K Stripe
4. LSI 53C1030T target mode Ultra320 SCSI controller running on a Dell PowerEdge 2600 Dual Xeon server. This is pretty cool, it's a system that's emulating four SCSI target drives in RAM that are striped by the host controller.

Read Speed: 239MB/s
Write Speed: 220MB/s

Abit IT7 with onboard HPT374 controller
2x WD 40gb 7200rpm 2mb cache in RAID0
Can't remember the stripe size, sorry.
F. Second partition on the array, first being 2gb SWAP partition that doesn't have enough space free to run the test.
Read 60mb/s
Write 63mb/s

I'm happy with that, especially considering the age of the drives/array itself.

I ran this on my browser box, just for comparitive purposes

this is for a Promise SX6000 w\128MB PC133 SDRAM cache
in RAID 5
w\ six Western Digital 40GB WD400BB HDDs (2MB cache) with 32KB stripe
on a 40GB partition that is 1\4 full
and some 41 other processes running in the background

Abit KR7A w\ 1800+ Athlon and 512MB PC2100
Read 21MB/s
Write 3860KB/s (definately in the red )

holy crap. my larger drive by itself, no raid.

80 gig maxtor 7200 2mb 6Y080L0 - 60% full

43.5 read
43.5 write

damn dude, how did you get in the 200's??? I've already been looking at raptors and 15k'ers, but now i think it's time to start learning more about raid as well.
