Aluminum Dual Bay Hard Drive RAID Enclosure with Cooling Fan for 2.5“/3.5" SATA HDD/SSD with USB A/C 3.0, Tool-Free HDD Enclosure, 4 Modes(Support RAID 1/0/JBOD/NORMAL)

I have been running this raid box for about a week now, only in normal mode for now, and it has been everything you would expect. The drives install easily and the case is very sturdy with quality plastic. I would point out that noise level is almost non-existent despite the description. I honestly can't even hear it with the fan I run also whirring. The packaging box was slightly damaged so, to safeguard my drives, I went through the reset procedure on the back of the unit before adding drives, just to make sure it had not been set to a RAID configuration if this was a return. My drives recognized quickly when inserted hot. No complaints so far.

awesome product. suited my needs and runs perfect. wish there was a diff way to interface with it on its own but its ok that its not as it does the job effectively.

This RAID enclosure is a great value for the price. I have 3 of them now and they were all very easy to set up and get running. The RAID mode is selected from DIP switches on the back, which is convenient, although you're not likely to change RAID modes once you set up drives. Unfortunately, like many inexpensive products from Asia, the users guide is replete with long descriptions in sometime garbled English, but the meaning is at least understandable. However, the photos in the PDF version of the user guide are very low-resolution thumbnails that are almost impossible to decipher when expanded. I boggles the mind why any vendor would create such terrible low-resolutions photos and then use them to illustrate their manual. Speaking of the manual, it's pretty thin on how to recover from drive failure (for instance in RAID1 mirror mode). But that seems to be on par for these budget electronic sellers.

It is extremely fast -- it bricked four Ironwolf NAS drives within seconds!!! I am a long time IT guy. User of RAID since the late eighties. Needed simple storage to offload some old files from my NAS. Set up and tested all four Ironwolf drives with SeaTools before installation and they were perfect. Installed all four (I wish I only had installed one...) into the enclosure and turned it on. Unit is supposed to come up as four separate drives which you then reconfigure into RAID config that you want to use. Four drives each lit up with blue (normal) led indicators, but the unit would never mount the drives -- no indication of USB device in explorer nor disk management. Powered down and pulled one drive out. Connected it directly via a usb cable and the drive would no longer mount. Left the drive connected with only power and it was usb recognized after approx 30 minutes (this is a hidden reset feature on some ssd drives). However, drive would still not mount. Ran SeaTools on the drive and found that the firmware values were all corrupted. Example, SeaTools stated the drive was 31245893.4 gB in size. Tried to use SeaTools to initialize the drive and it failed. Tried to use SeaTools to reset the firmware parameters I could see -- failed again. Therefore, I have two shipments to make on Monday -- sending this piece of crap back to Amazon and sending all four drives back to Seagate for warranty exchange. FYI , if you are brave enough to try this unit, please note that changing the config of the unit is not as simple as it seems. The unit uses dip switches, so you would figure that turning off the power and changing the dips would suffice. However, the procedure --not significantly called out in the very spartan manual -- is to power down, change the dips, hold the reset button down for ten seconds while bringing the power back up. The reset button is required to get the unit to recognize that the config has changed. I am wondering if my unit was a return that was resold and the dip switch config LOOKED as if it was set to factory default startup, but maybe someone had tried a RAID config and then set the dips back to the default without doing the "Reset+Power up" to flash the change back to factory default. Unit looked new, but OEM box had no tape on it and one of the drive trays was missing its "peel-off" plastic film. In any case, Caveat emptor!

So far so good. Using it on a linux home media server with 2x 20TB drives and RAID 1. Linux detected it immediately and after i set to RAID 1 and held the reset button it popped up as a HW RAID and GParted worked perfectly, now working to transfer my 8TB of Data to it. Biggest complaint is that the plastic rails take some fussing with to get perfect, but otherwise work great.

This was the only enclosure I could find that could handle 20tb drives. I bought it just to make sure and then bought the 6 bay unit. I use it to back up my 100tb compelleant array. Everything was easy peasy. I'll probably get another 6 bay although I can only find the 8 bay now, but that is fine. I plan to daisy chain them for redundant backup. We just moved and still unpacking, but these were some of the first to get set back up.

Cumplió con todo lo descripto. Funciona muy bien
