We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: AVADirect, GIGABYTE, Cooler Master, LSI and Noctua.

As we mentioned previously, the Silicon Image RAID controller has a couple of options. The RevoDrive comes configured from the factory, but some users may want to dip in and configure the drive for high IOPS performance or higher sequential reads and writes. There are a few other configurations that you can try as well. Let's take a look and see the options.
From the factory the RevoDrive is configured in RAID 0 with a 16K chunk size. That is all fine and dandy, but I know you expect more from us than just a single benchmark run.
Right from the start we found a couple of options that can really change the entire configuration of the RevoDrive. As you know, the whole premise is RAID 0, but the option is there to run JBOD or two separate drives. This can be a very good option for those looking to install their OS on one drive and your programs on another.
After you choose the RAID 0 option you are then given the opportunity to configure the chunk size. This will allow you to configure the array for higher IOPS performance or higher sequential read and writes.
For testing today we chose to run the OCZ RevoDrive as it was configured from the factory, RAID 0 with a 16K chunk size. We also ran the RevoDrive in RAID 0 with a 128K chunk size and as dual 60GB single drives.
ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
Here we see the ATTO performance of the OCZ RevoDrive as it was configured from the factory. Never before has a drive that cost less than 400 USD been able to break the 500MB/s mark.
