Pros: This a great product that functions just as the description says. Installation is quick and easy. Unit is quiet and unobtrusive. Email and forum support is fast and quite good.

Cons: None so long as you know what you are getting. No direct windows 7 support for RAID drivers. (The Vista 64bit drivers do work but are very old.)

Overall Review: Be aware: *This product is not HARDWARE RAID. *The manufacturer does NOT host drivers or software on their site. The drivers are hard to find if you don't know where to look for them. (Look on sansdigital's website and click on the community button). *Non-Windows hardware compatibility is spotty, view their forums prior to purchasing. All in all this is a GREAT product as long as you understand it's limitations.

Pros: This product is the best software RAID I have ever used. Setup is so simple I could have had my 3 year old do it. Have had no issues what so ever with this product. OS-Windows Server 2003 Enterprise Edition

Cons: Box does not power off if attached PC shuts down. (not a big deal since it is attached to my home server which is always on.)

Overall Review: This is a solid item for the usual price AND I got it when it was on SALE!
