RAID5 TESTING WITH 4 X TOSHIBA DT01ACA300 HDD
In our last battery of tests, we have set up SoftRAID‘ RAID 5, an exclusive software application that can be purchased with the Thunderbay 4. Reiterating what we stated earlier, RAID 5 is a striped volume and provides increased speeds commensurate with that. In our 4 drive configuration, the volume of three drives will typically be used while redundancy confirms data security of the volume. Remember… should one drive go bad, it can be hot swapped without loss of any data whatsoever. As well, this software is only available for OSX.
The opening page of the software identifies the version number and we can attest to the fact that it gets regular updates as we just received notification of one. Also, you may notice the ‘beta testing’ notification on the bottom which is for our use only.
The main screen identifies the volumes that can be included in the RAID configuration and one can simply right-click for individual drive options, or drag and drop the drive to the right. We grabbed this shot of the menu screen to show how detailed this software really is.
As shown in this screenshot, RAID 5 can be optimized for several different RAID environments. Now let’s take a look at the tests…
Highs of 536MB/s read and 534MB/s write are decent, especially considering we are using 3 hard drives to achieve this. It doesn’t quite reach OWC specifications that list 675MB/s read and 618MB/s write though. This could be the result of their use of the dual ThunderBolt 2 MacBook Pro, whereas our iMac uses dual port single ThunderBolt.
We probably wouldn’t have included this, but for the fact that we have displayed it previously and merits comparison for some.
Once again, Disk Speed Test pushes a bit harder and the results are evident .
