Pros: Very quiet. Moves adequate air volume.

Cons: Mounting on one side only.

Overall Review: The picture clearly shows that the mounts are only on one side. Works fine.

Pros: Large capacity. Nice form factor.

Cons: Got this for one reason: to back up my computers. It failed miserably. The backup runs okay for about 20 minutes then fails with an IO error. Have to unplug when restarting the PC. Custom connector? What ever happened to standard USB?

Overall Review: Contemplating whether or not to keep it as just as "extra storage."

Pros: Great value

Cons: Does not run at 1066. Would only stay stable at 1024. Small difference, but still.

Overall Review: This is another pair that I got from the same product line. Recommended, though confused about why it would not run at advertised speed.
