For the price this is a good entry level JBOD. I have added three drives to it and two of them were seen fine. The third was not recognised as having any data on it. I needed to connect this via its original USB housing and copy the data onto a different drive. Once the data was copied I installed it and formatted it again and it works fine. I dont know why it was seen as unformatted in this USB but worked fine in its original one. This would have been a major problem if all my drives were full. Luckily I had enough free space to be able to do this.
Pros: Looks good Easy to use Reasonably quiet when fan on low Good value
Cons: Cheap detachable door. Difficult to fit Power connector on side instead of back which limits where it can be located Very noisy if fan on high
