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.

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.

Very nice enclosure with good quality. Love the drive mounting method... no hardware required. The transfer rate of these particular enclosures is 5MB/s which is fine for use as a storage device... the larger 4 bay enclosure is a 10MB/s transfer rate. The RAID choices is very nice, too.The only problem I have experienced is that the drives do not spin down. They are always on and spinning. They can be turned on/off via the power switch located at the rear of the enclosure but in my experience, they should spin down via hardware command after period of time.

I'm using this on my Mac Studio as my Time Machine. I spent 15 mins trying to figure out what was wrong with this enclosure. I resetted it multiple times and nothing worked. I can see that when resetting its doing something but was not popping up on the Mac.Thankfully I have a Windows machine and so I plugged it in and it started working. And the enclosure identified the mode that I chose correctly which was Raid 1. I was also able to format the drive.So I came to thinking and hoped theres a firmware update because the description does say MacOS is supported and wanted to use this as my Time Machine. So I went to the site and found the firmware. They had two different model types, I also dont really know the difference. They have 802TC and 802RU. I tried 802TC and it did not work and then tried 802RU it started to work. The instructions were subpar, it had screenshots and and written in chinese. However, the document had a translation section in english which was nice.That being said after updating the firmware, it started to work on the Mac. And right now its finally backing up. I'm most likely going to return it, i dont know how reliable this is given that it did not work out of the box. Funny thing is that the firmware that came with it is the same version as the one I used to flash the enclosure. 'Like why did it work after the flash and not out of the box given that its the same firmware version'One thing to Point out, I may have the wrong version. The picture on the description has a flat rubber feet whereas this one doesn't, if anything it looks like the old model.

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.

Good indication lights on front panel that the thing is working.That's why I went for this enclosure.Zero hardware assy worked quite well, I like that alot. HDD fit secure and snug.RAID options are nice, though I am going with Normal mode, since if the controller fails, so are lost the RAID data.Recommend.update: the fan is a little noisy as the box heats up, so advice is to raise it on some foam pads and that will stop fan from resonating with a wood shelf (in my case).update 2: I am seeing write speeds to a disk inside at up to 1.5Gbps, so this puppy can move USB 3 data at a decent rate.

If you follow the directions on the back of the unit, they are wrong. It will not connect. It was not until I discovered that the directions and the pamphlet and the paperwork that it came in were correct. I can’t believe they made terrible mistake like that

I just needed a place to store a couple of old drives until I could get a couple larger drives to replace them.. the only thing I was worried about was if they would provide the full speed the drives are capable of, and yes indeed it sure does. Simple product, well made, perfectly functional for its intended purpose.One added bonus, if you have an enterprise drive that requires the special power adapter, they will work fine in this without it.
