Pros: The Hub works exactly as one would expect. It is magnetized so you don't have to use double-sided tape or anything to mount it.

Cons: A bit bigger than one would expect.

Pros: -Lots of storage for not that much $ -For the single day that all 4 drives were working I had 150 MB/s write and 370 MB/s read in RAID 10

Cons: -Very loud. If your system is setting on your desk, I wouldn't recommend it. -I order 4, 1 died after 24 hours. Click of death.

Overall Review: I got these because they were on sale and had similar performance to the drives that I was originally looking at. If I were to do it over I would have probably spent the extra $100 to get better drives.
