The downside of that arrangement is that when the very first of the four drives fail, I shed all data in the array. So I set up a RAID array, and went from below 6TB to much more that 7TB, with speeds of up to 130MB/S. Checked with Mediasonic and they pointed out that the WD20EARS is only developed for RAID or RAID 1. But then I got an additional drive failure light. Pretty speedy process to achieve, then I reset the mode, formatted once more, and I was superior to go. I switched it to a different bay, very same message, so I exchanged that drive. Tiny size enclosureCool and QuietCan't argue with the value Raid five apparantly not supported for WD20EARS 2TB Green drives I intitially set the box up with a RAID five array, but I kept obtaining an failure messages with 1 of the WD drives. Here is the procedure that worked for me:as root: 1) fdisk -l to see the drive letter assigned to the unittwo) parted /dev/sdN <- N being the drive letter assigned3) mklabel gpt <- you need to have GPT to see volumes larger than two TB - other sorts work, too4) mkpart primary 6001G <- I wanted 1 huge partition - this can be any size5) quitsix) mkfs.ext3 /dev/sdN1Mount the drive & edit /etc/fstab The trick to finding this to function below linux is employing the parted utility alternatively of fdisk. When I plugged it into the second linux machine through a Rosewill Silicon Image RC-209-EX PCI External e-SATA card it saw it as a 6TB volume. This could have been a USB issue or my machine hardware situation. I plugged the unit into 2 Linux (CentOS 5/RHEL5 -two.6.18 kernel) machines and by means of USB I was only able to see the unit as 2199GB (it ought to have been 6TB - 4x2TB at RAID five). When the jumpers had been set up effectively, the unit plugged into my iMac running OS X 10.six and worked completely by way of Disk Utility. If the jumpers are not set appropriately, added drives will show up as error/failed. The documentation for the jumper settings had been a little confusing since the image & the arrows explaining switch placement do not match up. The unit is extremely solidly constructed. It's incredibly good that it has connections AND cables for USB two./eSATA, & Firewire 400몸.

I bought this unit because of the good sale cost & the reality that it functions will Windows, Mac OS, and Linux (though linux isn't documented).
