1 out of 5 eggsTwo, both broke.

Pros: Easy to setup.

Cons: Bought one enclosure and drives in bay 1 didn't work (RAID 10, configured in BIOS). I swapped the drives around, the drives were fine in other bays but never worked in the top bay. This problem became worse over time, eventually my system would not complete a boot into XP unless bay 1 was empty. Bought a second enclosure to replace it, same problem, drives in bay 1 did not work in the RAID 10 I had configured in BIOS.

It doesn't appear to be possible to reinitialize a drive once it has been initialized. It doesn't appear to be possible to drop a drive from an array if it is currently degraded.

I lost power to the enclosure and the driver locked up my computer. After a hard reboot the 10 RAID array had been split into two, mirrored drives put into a second array with the same name. I had to delete the second array, add the drives back to the first array, and rebuild.

Manufacturer Response:

Thank you for purchasing our products.

Please contact us at 1-800-980-1988 or e-mail us at if you are having issues on the first slot. If the problem persist on the first slot with 2 different enclosure, it could possible due to hard drive compatibility issues. We strongly recommend on RAID edition or Enterprise level hard drives. Once the drives is initialize, you cannot be reinitialize. However, initialize the drives means allow the unit to use as RAID drives. It does require to un-initialize when using on different computer. Since your unit is covered by one years parts and warranty, Please contact us at 1-800-980-1988 or e-mail us at, and we will be able to help you out.
