4 out of 5 eggsSans Digital Tower Raid

Pros: Works as advertised. Simple to install drives, set up and maintain. Have had no problems with the unit, just a couple of drives. The unit automatically subbed in an extra drive I had marked as a spare. Worked great. Let me hot swap out the bad drive. I couldn't really gauge the rebuild time as I hadn't put anything on the drive yet.

Cons: The one con that was obvious right away when I set the tower up was the power button. It's not a 4 second hold button, it's a simple push on/off button, and it sits right on the front of the case. It WILL get accidentally turned off at some point. Why couldn't it have been a rocker switch on the back, or if they really wanted it on the front, make it a soft-off. Not a hard mechanical push on/off switch!

Other Thoughts: Not too much a con, but the raid card is a bit slow to recognize the drives and boot. The machine we have it on is always on, so this isn't really a problem for us, but I imagine it will get mighty annoying for anyone who boots relatively often. Or even daily boots, would drive me to look for another raid card.
