Mac Pro RAID performance test

[Spacedust]

Can you tell which tool I can you to test my new Software RAID 0 Array:

Drive#1 Samsung HD502HJ 500 GB SATA/300
Drive#2 Seagate ST3500410AS SATA/300
Drive#3 Seagate ST3500410AS SATA/300

Something like HDtach or HDTune on Windows. I know AJA.

Why do you have a RAID 0 of 2 different branded drives?

[Spacedust]

It's not a problem. They have nearly exactly the same performance (Samsung is a little better).

I've always used "disktest 2.0" It's not free, however I haven't found any of the freeware to do as good a job on stress tests.

Why do you have a RAID 0 of 2 different branded drives?

RAID arrays do not need to be made up of drives from the same drive manufacturer.
