I bought this to use for backup of my PC. First oddity I noticed is that if you turn it on and the USB cable isn't plugged into a computer, the unit will shut off within a couple seconds. This seems rough on the hard drives. I tried "stripping" mode to combine two disks so I could get more storage space. Within a day, the "rebuild" LED turned on (even after redoing the setup process a few times) and the volume was inaccessible. This was unreliable so I decided to use the device differently. I decided to use it to copy some important data off of a couple drives at the same time (in "standard" mode). These were different drives (6 TB and 2 TB) that I had for a couple years to store important data. I copied from these drives off and on over a few days; it worked well. Then, Windows 10 decided to reboot for an update (I thought I disabled this!). When it came back on, 6 TB total of data was lost. "The file system is corrupt". This was my first and last experience with StarTech. What a depressing failure. 8 TB of data, GONE! Thanks.

Promising but a failure.

I had 2 spare 16TB Iron Wolf Drives and needed a RAID 1 enclosure. This one did not advertise a 16TB compatibility. But, after hooking directly to the USB 3.0 Port (no hub) and letting the RAID Mode finish it's config, the Device showed up and away I went into Backup Heaven!

Works with 16TB!!!! Yay!

This enclosure has been solid for quite some time. Probably just outside of the warranty period. Everything was great until the fan started making noise randomly. It is not easy to replace unless you have tiny hands.

Awesome Minus Cheap Fan

after around a year or two of constant work as a server raid datastorage the fan stopped working. Replacing it is possible but plug is a bit hard to reach. The documentation, especially for the LED signals should be dramatically improved - some forums are better information sources than the official manual. Something I am currently struggling with and I can't find any info about, is if this enclosure is compatible with 4Kn drives - I have put two 6TB 4Kn (HGST) drives in now and did some tries but do not have the feeling it works (attached via eSATA or USB to a Ryzen 7 system on win10). One LED is constant blue, one LED is constant purple (=red) for over half an hour now and the PC doesn't detect anything. At some point the discs also slow down. Same situation with only 1 drive plugged in. The HDDs themselves are new and both ok and detected fine when directly attached to the internal SATA ports of the PC. The controller is a JMicron - JMS562 which (bad) documentation is also not mentioning 4Kn support, only Win8 compatibility is assured which would speak pro 4Kn, but I fear this is not the case. The enclosure itself is rigid and easy to use. the eSATA cable could be fixed a bit better, but it's ok. the probably missing 4Kn support and the bad LED documentation as well as the broken fan however make me rate it with 2-3 stars max. Oh, and I also lost the raid 1 one or two times with the old disks and was glad I had some backups...

rigid case but has areas for improvement

I had it for 4 months. I wanted a Raid0 for my games. Tried the 3.0. USB cable and it initialized great but I lost my raid after a couple of days. Also, I had to connect and disconnect everytime my laptop when to sleep or idle for too long. I tried disabling all USB sleep times and nothing. I kept losing my Raid0 after a while. Then I got a brainstorm and decided to use the eSATA to USB that I bought with it which I did not think I need it. I connected the eSATA side to the enclosure and the USB directly to the laptop bypassing all HUBS. WORKED GREAT. It has been three months now and my Raid0 is intact half way full with games and works super fast and my games have no lag whatsoever. the only thing I dont like is this humming sound it makes when it turning on or off. It makes me feel like is about to fail. Is not my drives is the enclosure making that weird, old sound humming. Other that that, it has been working great with the eSATA to USB cable.
