GRAUGEAR NVMe M.2 SSD Duplicator Dual-Bay Offline Clone Tool-Free, 20Gbps USB C to M.2 SSD Drive Cloner Docking Station Adapter Enclosure for M2 SSD Hard Drives M-Key

I seldom go into the performance because unless one can validate every component used can perform at the optimal 40Gb, then honestly it is a moot point. All I can say is that to clone a standard 1TB (480GB used) 2.5" SSD drive vs a Nvme 1TB with the identical data used. This one finished about 20% faster than my old Sabre 2.5" SSD clone dock. That is good enough for me. We are going have to trust that the vender can achieve promised speed at the lab. It is a little expensive, honestly, It does do what it promised to do which is clone another drive. SSD runs hot even with the heatsink and fan running. The temp tests was about 62C, maybe my house is hot as well. Anyways, I was able to test cloning TB NVMe drives, it does work without PC. Works for me and well.

This review is for the "GRAUGEAR NVMe M.2 SSD Duplicator Dual-Bay Offline Clone Tool-Free, 20Gbps USB C to M.2 SSD Drive Cloner Docking Station Adapter Enclosure for M2 SSD Hard Drives M-Key" that I ordered via the Vine program.I've been looking for a NVMe cloning/docking station for a while now and this one seemed to have the features I wanted. It has recognized and provided access to any NVMe drive I've plugged into it. Access speeds have been acceptable but not record setting. I haven't tried the offline cloning function so I can't speak to that.I did notice that the drives get very warm under heavy use, particularly when not using the included heat spreaders which are very fiddly to work with and are secured via rubber bands. I was hoping that the fan setup with the clear surround would provide decent cooling, but it didn't seem to make a noticeable difference.Overall, the unit is light weight and cheaply made. I don't see the support tabs lasting very long unless extreme care is used when inserting or removing the drives. The clear tube simply sits on top of the unit rather than physically connecting in any way. The dock does come with everything needed for use, but the heat spreader solution seems like an afterthought.The unit certainly provides an easy-to-use dock for quick access to drives not installed in a device which is what I mostly need it for. I'm wary of its build quality but only time will tell how long it lasts. I was hoping for a better cooling solution, but so far, the drives haven't gotten warm enough to thermal throttle during use. So, based on my experience, I can still recommend this device.

Super easy to use and does exactly what it claims. I use this to quickly and easily upgrade from a 1 TB to a 2 TB SSD without all the time and effort that it had required in the past to make and load images. Definitely happy I picked this up.

Easy to use, you don't have to have it plugged into a computer to use, and its fast! I like that it has a fan and heatsinks, because when I tried to use my old USB m.2 connector the drive got super hot and slowed way down. this allowed the drive to work quickly while keeping it cool. It's also quiet.Great tool if you are working on computers and need an easy way to upgrade your Nvme to a larger model, or if you need to change it out because its not working so well and nearing the EOL of the older drive.

The "GRAUGEAR NVMe M.2 SSD Duplicator Dual-Bay Offline Clone Tool-Free, 20Gbps USB C to M.2 SSD Drive Cloner Docking Station Adapter Enclosure for M2 SSD Hard Drives M-Key" I received works ok.I have some caveats about the design. First, the power supply has a permanent wire so if it fails when I need it most, I'm down until I get another 5v 2A supply with a barrel connector.Second is the cooling design. The tube can actually make the ssd(s) heat up more due to the fan not being able to blow out heat building up. Removing the clear tube and placing a decent fan so heat can be better removed may prove more efficient under some circumstances.It's a bit expensive imho. The heatsink attachments could be better for the price, and heat management should be reconsidered. The power supply issue is the other reason I believe the price is a bit high.However, it will clone up to an 8TB ssd which is useful as larger ssd drives are becoming more affordable. I'm glad I have it as it can also manage one drive- format, read or write to it, etc. Cloning for me is a great bonus.
