MAIWO Hard Drive RAID Enclosure Dual Bay for 2.5 Inch SATA SSD HDD, USB 3.1 GEN 2 10Gbps with UASP, RAID 0/1/JBOD/PM, 16TB Capacity, External Hard Drive Reader Case Aluminum

This case is build great. Easy hard drive install. Setting up mode is super easy. Good speeds. Works Excellent! Couldn't ask for a better hard drive enclosure!

Raid is something I MUST have and this case does exactly what I need it to do. It's been in play for a couple months now and I use Veeam Agent to backup daily. I actually tested the mirror raid by removing one drive and it worked seamlessly. The all metal casing is sturdy and well made. For this price I think I got a fantastic product.

Bought this as a cheap interim fix for another enclosure that died after 4 years. Install is fine, I configured the switches for RAID-1 (up and down). Enclosure appeared to work fine, except today I noticed that it was in "normal mode". Another reviewer mentioned this problem as well.However, the bigger shock is that it wasn't actually doing RAID-1, ever. I noticed that I had a new disk attached according to Windows Disk Management, which would be correct if the RAID-1 got turned into "Normal Mode".However, it turns out that the second drive is completely empty and uninitialized, so it obviously is NOT mirroring and hasn't been since I installed it.Avoid this product!

Initial impressions are good. It has a nice aluminum case, and the entire thing is very compact, yet holds 2 SSD's. It comes with 2 cables: 1 USB3.0 for the data transfers and 1 micro USB for additional power that you probably won't need. It also comes with 4 screws a small screw driver so you can attach the drives to the tray (optional), and secure the tray to the aluminum case.I had a practically identical product with the Vantec Nexstar GX, but I had to return it because it just wouldn't work reliably. Interesting to me is that the Vantec Nexstar has alot more purchases and reviews and even has the Amazon Choice tag, but I had alot of problems with it. Maybe I just got a bad unit.So far this Maiwo unit is working the way I hoped that the Vantec Nexstar GX would work, and has the same (maybe even slightly better) build quality. It was also alittle bit cheaper than the Vantec. This is just an early impressions, and I only have 1 SSD in the unit right now for testing purposes. At this point, the only thing I would change is I would add a power button so I can leave it plugged in to my USB hub but still disconnect it and turn it off when not in use.

<update>I've forgotten that these DYI enclosures have lead to tears. I was looking forward to happily using my 4tb drives and forgot the bad of the past. The faster drives with the enclosure had my Mac warning me "Disk Not Ejected Properly" see attached. It ejected itself, and seemed to corrupt the contents, both in "Large" and "Normal" modes. It seemed intent on going to sleep would be my guess. No dashboard, so I'm not sure. Returned.I've ordered an assembled WD 2GB drive and will be using it. Cost the same as these 2 enclosures.</update>Sadly Drobo Inc (or their parent company) has failed me the dashboard hasn't been updated for MacOS Ventura, so I'm moving on, Beyond RAID or Beyond DROBO (hehe). I'm not sure if I need a RAID.I'm moving my User Folder off of the internal drive on one of these units using the 4X1TB drives from the Drobo. in Large mode. And will have 4TB on 2 drives for backups. I have an existing drive.Playing around with the switch settings last night left me with nothing that would mount, the instructions are hard to read and unusable. I went to bed. This morning they both work (after resetting them). RAID 0 doesn't seem to work for me (see screenshots Raid 0 on the left) perhaps I need to buy faster drives.Opened box, nice presentation tray with enclosure wrapped in plastic. Remove plastic and "Sled" falls out of "Tube". Lift plastic tray and there's a lot of stuff, 4 screws (2 long, 2 short), UBS 3 cable (Data) USB 2 cable (data), and 2 screwdrivers. Bagged nicely. Popped drives in "Sled" plugged used long screws to stabilize drives (1 each), into Mac received "disk unreadable" error (good), put "Sled" in "Tube", put screws in, plugged in and formatted.Good:Inexpensive and fits what I want. Solid box when installed, easy assembly. Metal on outside.Bad: "Sled" is plastic, DIP switches seem fragile, be careful. Not quite sure how to reset drives, but I have them in Large Mode, which is what I wanted. LEDs flicker when you eject the disk, but stay on after, so you're not sure if they are unmounted. No feet on drive. I'll add some. LEDs don't tell you drive is sleeping. Bad documentation.YMMV: LEDs are not too bright, but can't seem them on the shelf under my desk(where they will live, vertical). When not sleeping , they run warm. Don't know if my user folder will allow it to sleep.Satisfied.

Bought the 10Gb/s version (K25272C) to go with the Mac Mini M4. Getting practically the same speed as connecting the SSDs via internal SATA (500+ MB/s) on a PC. (Obviously you can't get more speed than what SATA is rated for.) Have been using it for a few days without turning it off and did not encounter any random disconnect. No issue with thermal as well. (I believe 2.5" SSDs don't really get hot to start with).

I can only assume the previous reviewers are the type if people that buy something and are happy if it works. Does this "work?" Yes. But it does not work well. It does not transfer anywhere close to as it should, and I have to say this is garbage tier hardware. I was planning on installing my Steam library on 2x4 samsung 4tb SSDs, but it cant even seem to make it through one game install without clapping out and needing to be unplugged and plugged back in. The sustained data transfer is such that the device really isn't an upgrade from my existing WD Red 14tb in an external case

Solid case. Great value. Easy Drop in drives, secure with long screws. Slide into case. Secure with short screws. Set raid type. Press reset button.
