How do I find out my raid speed?

[dubaimac]

Morning all,

I got my Intel Gen2 SSD's over the weekend, and have installed them in Raid 0 using icy dock converters, I cloned my OS onto there from my caviar black raid 0, so I want to run some sort of throughput test to compare the two, not application specific as I don't do any of the CS4, video stuff, just plain old read and write tests, please can you tell me the application to use,

I will then post the result here as well,

AJA tests are great for testing sequential speeds. For random I can't think of any tests at the moment.

people here use the disk section of xbench usually.

Yeah they do but only cuz they don't know any better.

XBench sucks major nuggets!

The best free utility for testing drive and raid speed is IOGauge from Santools.

Number two would probably be the AJA System Test: http://www.aja.com/ajashare/AJA_System_Test_v601.zip

XBench is lame and Geekbench is just a waste of time and diskspace all together. Even though as you say, people use it a lot.

Speedtools is pretty good too ( http://www.speedtools.com/ ) but it's not free.

Thanks for these, using the aja, I can't get the other to download, my caviar black raid is showing 200mb/s in all tests of read/write on a 512mb file

the ssd raid is showing 149 write and 472 read on a 512mb file

is this what I should be expecting? Thanks in advance
