3 out of 5 eggsDoor stuck, not quiet

Pros: Small, lightweight

Cons: After changing a drive about two dozen times one of the doors refuses to open. I can't figure out how to force it open without breaking the case. I did not abuse it. Poor design.

The fan is not the loudest, but very noticeable. It may be hot-swap but when I remove one drive both drives go offline. Does not work reliably with Ubuntu 14.04.

5 out of 5 eggsWorks fine

Pros: Works well with data transfers. Easy swap on drives. USB3. Using 4tb seagates in RAID 0.

Cons: As stated before, controller on board causes unit and drives to fall asleep.

Other Thoughts: I don't understand why the other people are freaking out over the drives falling asleep. Yes they do "power down" but when you initiate a file transfer or a file browse it initiates a spin-up on the drives. I am mainly using this as a backup drive, then pulling the drives and storing them. If you're using this as your everyday storage device, you should have just put some drives in your computer and been done with it or in a non-hot swap case.

3 out of 5 eggsAfter some tweaking seems to be working well.

Pros: Simple and quick to install drives.

Small footprint.

USB 3.0

Cons: Power saving mode is automatic and not configurable via hardware or software switches.

Other Thoughts: I've got this attached to a very old Windows Home Server box. This box is a collection of old parts but it has served me well over almost a decade.

One can plug the SAT3520U3R in to a USB 2.0 port. You just have to be sure to use a USB 2.0 cable and NOT the cable that came with the unit.

In the end I ended up writing a simple batch file that adds a single character to a file on the drive. I then used the Windows Task Scheduler to automatically execute this batch file every 3 minutes. This way the unit never automatically powers off.

All in all I think I'm happy with this unit.

1 out of 5 eggsi hate it

Pros: allows two drives to be put into one box

Cons: The drives un-mount and hibernates after 5 minutes, apparently the manufacturer thinks this is cool. I hate it, you need to unplug and re-plug to get the drives mounted again. It does it in linux windows and even mac osx. There is no way to stop this behavior !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Other Thoughts: If I knew it would do this I would have NEVER bought this enclosure !!!!!!!!!!!!!!!!! I am going to send it back for a refund !!!!!!!!
