MAIWOM.2 PCIe NVMe SSD Enclosure Dual Bay with Offline Clone, 20Gbps USB 3.2 GEN 2x2 Type-C to M Key Solid State Drive Adapter Reader Duplicator, 8TB Capacity

I used this to clone a SSD drive for the Lenovo Legion Go and it worked fast cloning the SSD drive to a new 2TB SSD. I used the off line cloning function and worked perfectly fine. Highly recommend this product, especially when it's on sale.

Had to download clearer instructions after purchased, but after that, it has cloned several Hard Drives that we have used as needed.

UPDATE: I just tested this enclosure on a USB 3.2 Gen2x2 (20gbps) port with the included cable and speeds where not good- about the same as with the 10gbps port- 1000-1100 MB/s. I discovered the included C-to-C cable from Maiwo does NOT support USB 3.2 Gen2x2 20gbps speeds. Removed 1 star. (To comment on the Amazon reviewer "One Man" from Canada here, NO, he would NOT have gotten 20gbps speeds with the included cable) I purchased a $27 USB 4.0 (40gbps) cable and then, the R/W speeds were a respectable 1780 / 1686 MB/s but I think speeds are still limited by this enclosure's JMicron bridge chip as R/W speeds could be around 2000 MB/s for empty 1TB Samsung 980 NVMe's. During this 20gbps port speed test, the drives never went above 43C. To achieve better cooling, I applied different thicknesses of thermal pads to compensate for my NVMEs' uneven height- 1mm thick to the higher part and 1.5mm to the lower part. That way, when the aluminum strip is applied, it's more parallel to the the enclosure parts for better contact.ORIGINAL: This quality device, created with minimal tolerances where the outer aluminum shell fits nicely and snugly to the chassis with the thermal pads adhered to the tops of the NVMEs. Great workmanship. Once the NVME drives are secured in the chassis with the rubber push pins, then adhere the soft 1mm thermal pads directly on to of the NVME labels and then on top of those, adhere the aluminum strips. (DO NOT remove the NVME factory labels.) When sliding the enclosure back together, make sure the rear thermal pad doesn't catch and dog ear.The R/W speeds (with a USB-C 10gbps port using Samsung 1TB 980 non pro NVMEs) are 1064 / 1030Mb/s respectively. Still have not thoroughly tested the temperatures, but during the Chrystal Disk Mark 10gbps port speed tests, the temps never exceeded 34C. I will update this review after testing it on a USB type-C 20gbps connection. The provided USB cables (both C-to-C and C-to-A) are generous at 32" long and seemingly nice quality. I have not yet used the Clone function. Since I manually backup files, I plan on frequently using it's power button and hope it's robust enough for many repeated presses.

The card retainers are of poor material.

The only complaint I have is that I thought it would be faster doing an offline clone than online. It isn't. I think this is likely caused by having to go through both nvme->usb controllers. It would be better if, when offline cloning, there was a nvme->nvme path.

Works great but must be sure your ssd is of a compatible type .

6 hours for an offline clone from a 2TB Samsung 980 to a 4TB Samsung 980.

This cloner has cleaned up the source SSD twice during testing. This is an absolute nightmare scenario where the copy of data you are trying to back up itself goes up in smoke. This must never happen, under any circumstance.Amazon this is not a question of hundred bucks for an individual, or thousands dollars worth time wasted testing a substandard product. This is a question of invaluable data safety. Do you have a responsibility? In a strictly legal sense it seems you don't. But given your market power and reach, you are a big time enabler of proliferation of substandard IT products. It's about time you created a QA barrier of your own to stop this.

I tested this on a regular USB C type 2 (10 GB/s) port and also on USB C type 2 x 2 (20 GB/s) PC port. You can find this output on Dell XPS 8950 at the back. Front port is just 10 GB/s. Note: the test was done with a high speed (20 GB/s) data cable (Amazon: B085HL184P, CAD 15 for 6.6 ft) and results were 1800 GB/s read and 1700 write using Samsung EVO 970 Plus 500 GB. With plain USB C data cable I got about 1000 GB/s read and write. I am not sure what results would be with data cable supplied with the device (I am not sure anymore which one came with the device).

The problem is that it will not show the one or two mvme until it is powered if its what you need to clone an mvme you mind as well use the software because its not for storage unless the power is connected to show the mvme s ssd ALSO COULD NOT RETURN DUE TO A SHORT PERIOD RETURN THEY WILL ALWAYS GET YOU SOME HOW SPEND YOUR MONEY ON ENCLOSURE NOT THE FACT THAT IT CAN CLONE BECAUSE THE SOFTWARE WILL CLONE AND THE FACT THAT IT HAS TO BE POWERED EXTERNALY IS RIDICOULUS FOR SHOWING MVME

It's my fault I suppose but I thought I would be able to put 2 HD in the device to be read by the computer.

Product never work! Deceiving.

Works great and 2 x 4TB nvme drives for light usage. I've been trying to copy 600GB to one of the drives and the device disconnects from the bus (The blue light goes off) at around 300GB. The idea is nice and it does have a nice heat transfer mechanism, but I believe the USB controller is at fault here.
