Pros: While not explicitly mentioned as a supported OS, the drivers for included RAID card DO work under Windows Server 2008. Very quiet fan. One eSata connection for all 4 drives. Plenty of expansion room with 4 drive bays. Nice glossy black finish.

Cons: Some may not like the blue LED fan in the rear. Its growing on me though.

Overall Review: First boot with the RAID card installed, Dell PowerEdge T105 server showed an error about IRQ conflict but once the driver was installed that went away.

Pros: Based on reviews, wanted to make sure it worked with Dell SC 440. Thanks to previous review. Works perfect. No problems. Quiet, well built, i kind of like the blue light glow. seems like it will last. The instructions were very good with screen shots for all systems including windows 2003, Xp, vista and Mac.

Cons: None at the moment

Overall Review: will likely buy a 2nd unit and have it attached to my mac! looked at the other brands, inc. sans digital. glad i chose this one. using 2 640 gb WD disks also ordered from new egg. everything works perfect. not having any of the issues you read about with drives failing or noisy or rebuilding. glad to have 2 extra bays for expansion.

Pros: Works very well with a Dell Poweredge SC440 server and Windows Home Server. Easy installation and setup. Drives mount quickly with thumb screws. Good airflow and quiet. Low power consumption.

Cons: Annoying blue LED lights on the rear mounted fan. Looks like a blue flashlight shining on the wall at night. Very little tech support available on mfr web site (China), but email to tech support for drivers was answered quickly.

Overall Review: This is a great way to expand storage. I am not using the raid software, just the PCI-E card drivers. So far so good. Nice fit and finish on the enclosure, although gloss black finish does show fingerprints. Comes with a wide range of drivers to support both 32bit and 64bit operating systems including server 2003. As an FYI, it takes FOREVER for the esata card driver to install. Something like 3-5 minutes.

Pros: Holds four drives, hot swappable. Includes cable and esata card for PC. Install was completely smooth (one night after coming home late from work). Everything works great.

Cons: I have no real complaints. The cover is a little tricky to get back in place, so I will not use thumb screw to hold in drives I plan to remove.

Overall Review: Also bought 2 WD green 1TB drives (so far). I am dumping HD movies from satellite dish on them. This enclosure seems ideal for this application.

Pros: Nice build quality and incredibly quiet. Great airflow - runs 10 degrees cooler and 10-20MB/s faster than another comparable unit. Drives slide into a backplane rather than messing with cables. Includes thumb screws for everything.

Cons: Exhaust fan is lit with a blue LED.

Overall Review: Overall very nice - I currently have 8 in the office, and plan on purchasing another 4.
