MAIWO K35272C 2 Bay 3.5 inch SATA RAID Storage Enclosure, Dual Bay Hard Drive Docking Station to USB3.1 10Gbps, Support RAID 0 /1 /Large(JBOD) /Normal Mode

Very well thought out. Very nice materials and construction. It is fast. Use it for Thuberbolt 4 port connectivity, which is way faster than the 2 ea. RAID-0 HDD's that are in it. They top out at about 410 MB/sec. read speed, which is only a fraction of the 10Gbps that its interface sports. Aluminum for cooling, adjustable cooling fans, and auto-sleep when not in use. All plusses.

What I like is that it works and it is easy to set up. Materials are mediocre. The inside is a cheap feeling plastic. An interesting aspect is that the cooling fan is manually controlled--I not sure that is good, unless you just run it full time. I had an another enclosure that was a little less expensive and made far better will all metal parts. Problem is it did not work and I was not able to get it repaired or replaced.

When i set raid mode on two identical size new drives I can reset the device to the right light coming on, but windows finds a disk in disk management that it not accessible, it says 'no media' and you cannot format/partition/initialize the disks.I think I got a faulty unit.So I just accepted a normal mode dual disk backup setup that requires me to put data on each drive separately.. so its slower than raid zero and more hassle than raid 1, but at least it somewhat works.Surprised no-one else had this problem.Support on the site is Chinese and presents an error message when submitting the contact form, no firmware appears available, so I cannot fix it.

Bought this to use two smaller drives to back-up my larger server drive. Set it up as a RAID0 to see if there would be a 2X speed increase. Not at all. Maybe my USB speed was the limiting factor, but in my case there was no reason to go with RAID0, so I went with "Large" since 1 disk failure will not destroy every file due to striping. Did a 23 hour back up. All appeared to go well... until I tried to remount and verify the files. Disks would not remount. Tried pulling individual disks and mounting independently - neither drive was recognized by Linux OS. Apparently the controller does some proprietary Partition/FAT. Not good for actually trying recover data if there is a failure. Decided it was MUCH SAFER to just use individual disks as partial back-ups.

If you want something that's inexpensive and works, this is for you. I especially like that you can take it apart and remove the small USB to SATA adapter and use it for special projects (like internal hard drives for servers and thin clients).

I was looking for a two bay external raid enclosure for backups. The enclosure is a simple, sleek design essentially a metal encasing you can insert two 3.5 drives. The enclosure also comes with the screws and two different screw drivers for installing and setting up the enclosure. (Note the enclosure is not intended to be hot-swappableOn the back of the enclosure is the “on” switch (it would have been more convenient if the on switch was on the front), fan control, raid rest button, raid setting dip switches and blue light indicators showing what raid level is set. Setting the raid was really easy, I just followed the instruction on the website1)Turn on the Power 2) Set the raid level on the dip switches, 2)Hold the RESET button, 3) Turn off the power switch and then turn it on, 4) Wait until blue raid indicator lights up indicating raid level is setI didn’t get a chance to test it out, but the case also advertises 3.2 Gen 2 speeds (10 Gbps). Technically an SSD only needs 5Ggps but I prefer a USB connection that has more capacity than required. On CrystalDiskmark I am getting around 207/205 MBS r/w, which is what I was expecting for a 7200 Toshiba N300 drive.I am very happy with this case for the price, it works perfect for backups. There are a couple of different retailers who sell this case on both on amazon and china direct, so watch out for sales.

Two for two.I ordered one of these dual-bay enclosures. It arrived without the necessary power supply. Amazon sent a replacement and the second unit also arrived without the power supply. The unit is not self-powered and requires a 12v DC 1.5A power supply (about $5 on Amazon).Other than being unable to power the unit when it arrives, the device is actually nice looking, decently constructed, and full featured.The drive carrier is plastic and one or two drives of any capacity slide in and are then screwed in. The enclosure itself is extruded aluminum with a beveled edge that fastens using three provided screws to the drive carrier.The unit features a fan with a manual off/low/high speed switch. The fan is silent. RAID modes are 0 (stripe), 1 (mirror), JBOD, and "normal," which exposes each disk separately. There are LED indicators on the top of the unit for disk activity and on the back of the unit for RAID model selected (via DIP switches). There is a legend printed on the back of the unit showing the four possible switch positions and what they do.Nice enclosure. Disappointing delivery. Of course, Amazon came through in the end.

Bought this for local backup of a Synology NAS. When the Maiwo 2 bay goes to sleep, it completely disappears from the Synology as an external device and has to be unplugged and then plugged back in to be seen. There should be some way for setting the Maiwo sleep mode, but they apparently do not have a web page that I can find and there is no link to them (other than a store) on Amazon.When the product is seen, it works well. Maiwo, please contact me. Is there a fix?
