GRAUGEAR 40Gbps M.2 NVMe SSD Enclosure Docking Station, USB4 External Docking Base with Cooling Fan, UASP Trim Support, Compatible with Thunderbolt 4/3, ASM2464PD Chip [G-M2DK-U4-40G]

The media could not be loaded. Its just a beautiful piece to set next to my Alien 👽 M18 R2 gaming laptop. Like I said its functionl even though I'm only seeing 650MBps (about 5.0 gbps). I was promised 7.5gbps. Its still fast AND BEAUTIFUL. I emailed this company about 2 months ago and complained that they only had 10mbps speeds. Now they have 40mbps so I jumped and boughy one. They perform adequately so I will be buying more. Did I mention that this are works of art ? They need to include the pure copper heatsink (as I have pictured) to justify the beauty. It only costs a few bucks more. O and they need lighting FX. I will b adding my own but they need it. Did I mention this is a beautiful piece of art ? Lol

My wd_black sn850x 8tb with manufacturers heatsync works ok 1 gb/s but slows down when it gets warm to about half that. I have it connected to my thunderbolt port on my alienware m16 r1. Overall I am satisfied

I think that this is an absolutely wonderful product and I greatly enjoy using it. There is nothing about the product that I do not like. If you are working with a lot of NVME drives it is quite easy to remove the one that you have finished working on and then insert another one. THERE IS ONE THING THAT I WANT TO MENTION. YOU CAN READ AN WRITE TO ANY MICRON/CRUCIAL NVME SOLID STATE DRIVE THAT HAS BEEN FORMATTED and YOU CAN FORMAT and CHANGE PARTITIONS USING THIS ENCLOSURE. YOU CANNOT USE THIS ENCLOSURE IN CONJUNCTION WITH MICRON/CRUCIAL's STORAGE EXECUTIVE PROGRAM TO MODIFY THE FIRMWARE OF THE NVME SOLID STATE DRIVE AND YOU CANNOT EXAMINE S.M.A.R.T. PARAMTERS. THE STORAGE EXECUTIVE PROGRAM SIMPLY DOES NOT RECOGNIZE DRIVES THAT ARE ATTACHED TO THIS INTERFACE.

First off, don't believe the Amazon vine reviews! 2nd, this is junk. Really disappointed. I thought the design was actually kind of cool but it is cheaply made and has several issues. The biggest annoyance is the fan is super noisy and you can't turn it off without disconnecting the drive from the computer. They should have included a separate on / off switch for the fan. The round clear plastic tower does not fit well, they need to re- think how it sits in the base. The usb connection is cheap and doesn't plug in very well. Until they fix these items, you should pass on this. It's not worth its price tag and I highly recommend you don't buy it. Hopefully they are listening, and will improve it with a future release. If they make those changes I would consider buying it again.

I was able to get 2900-3000 mbps read/write speeds with these and I was amazed. It’s a solid product with an excellent look. I ended up returning it because of concerns of dust due to open top design.If you have a stationary setup, this is perfect. The look is awesome and the setup was easy, the speeds were impressive.

While this enclosure blazes when connected directly connected to my M4 Pro Mac Mini, yet undetectable when connected to the OWC 5 Port Thunderbolt Hub, yet various other external storage devices worked fine when connected to this hub.

The transfer rates are great for a thunderbolt 4 connection to my Mac mini m4 with a Samsung 980 Pro Ssd w/heatsink but the unit has developed a fan noise that is quite loud after a very short time.

internal fan is loud for its size and slightly annoying. loud enough to be useless in a recording environment.Works well otherwise.
