In response to last reviewer...
Pros: Inexpensive, SFF-8088 connection, 6G supported
Cons: pay for what you get(cheap feel) no hot-swap trays, though there is a reason
Overall Review: I only have the eSATA version of this enclosure, but they look virtually identical, physically and mechanically - minus the external connections. It does have a cheap feel to it. The top cover is very bothersome to remove, although you don't really need to remove it, once it's running. Regarding the post about no trays, the drives just slide into the enclosure bare on built-in "shelves"(shown in the second pic on the product page). This has both pros and cons - PROS: no need to buy extra trays for replacement drives. Just pull out old drive and pop in the new drive. Cons: Can be pretty difficult to pull out any of the top 3 drives, since room to get a grip on the drive is minimal, and with no tray handle to help. This can get worrisome when the device is live. It requires one hand holding the enclosure down and some force to pull the drive out. It's almost impossible to remove the top drive without powering down the unit. My only suggestion to Sans Digital is provide some tool that could reach behind the drive to help pull it out. I was thinking of using a spare expansion slot cover, but there is circuitry behind the drives. If you want an inexpensive 4-bay SAS enclosure, this would be one to get. If you want the perks of drive trays and enterprise-quality build, you should be looking at a rackmount system.
