Areca ARC-1882i and Corsair Force GT 7 Drive SATA III RAID 0 Setup

By: Shawn Baker | RAID in Storage | Posted: Sep 8, 2011 2:54 pm



We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS, MSI, Western Digital and Corsair.


On the testbed side of things there isn't anything out of the ordinary when compared to other recent reviews you'd have seen me do. On the motherboard side of things we've got our trusty ASUS Maximus IV Extreme-Z which sports the Intel i7 2600k.


We've got a MSI GTX 580 installed today, but that won't really be getting much of a work out. Windows will also just be running off our Kingston 128GB SATA II drive that we've been using for a while. Of course, the products that really stand out today are the SSD and RAID card which we covered on the previous page.


Let's get started!



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.



Left: 1x Corsair 240GB Force GT SATA III - Right:2x Corsair 240GB Force GT SATA III in RAID 0



Left: 4x Corsair 240GB Force GT SATA III in RAID 0 - Right:7x Corsair 240GB Force GT SATA III in RAID 0


In the first two screen shots you can see the kind of performance we get under the ATTO Baseline test. It can be a little hard to read, so if we just throw the highest numbers into the graph we get a better idea of what's going on.




Checking out the write numbers, we get an excellent idea of what's going on with performance and what happens as we add more and more drives into our RAID 0 mix. From a single drive to a two drive RAID 0 setup we go from 568 MB/s to 1063MB/s.


Moving to a four drive setup, we see that doubles again to 2025MB/s. Moving to seven drives doesn't quite see the same linear jumps in performance, but we do see a massive 3003MB/s maximum write speed.
