GRAUGEAR M.2 NVMe SATA PCIe SSD Enclosure Adapter Docking Station with Cooling Fan, USB3.2 Gen2 10Gbps M.2 SSD External Case USB C, Support UASP and Trim, M2 NVMe NGFF M Key B+M Key, RTL9210B Chipset

The boot drives for my desktop and laptop computers have heat sinks permanently attached to them. Normally, when I need to externally attach an M.2 NVMe drive to a computer, I put it in an external enclosure without the cover or thermal pad attached. However, my boot drives won't fit in that enclosure or any other ones I have. This dock is one of the only two I found that would allow me to plug my boot drive into and have a way to support them after I modified it.The fifth picture shows my boot drives. The bottom one is actually in a tray that slides into a dock on the back of my desktop computer for easy access (instead of having to halfway tear down my computer to get to it). Because of the thermal pads and compound inside, removing the drive inside would be difficult and messy. The top one is for my laptop (fortunately, easy to access). Its heat sinks are permanently attached.To be able to support these drives so they won't flop over, destroying the drive's connector, I had to modify the clear plastic "chimney". First, in the sixth picture, I had to cut away the wind vanes on each end of the socket in the base and the little retaining clips on each end of the socket to accommodate the width of the larger boot drive. After that, in the fourth picture. I shortened the "chimney" by one inch, made a plastic disk with a slot and two notches to clear both boot drives, then cemented it inside the top of the "chimney" as shown in the third picture.The first three pictures show the boot drives installed in the modified dock. The fit around the drives is loose enough, plenty of cooling air should still flow over the drives.I didn't bother with the included heat sink. I already had heat sinks installed on the boot drives, the included heat sink is too light for my needs and only cools one-sided SSDs, and I don't trust the elastic bands holding the heat sink to the SSD to last very long.The "chimney" will lock into the base, although it is more a friction fit than being locked. I'm going to leave the "chimney" attached when the dock isn't in use to avoid wearing out the fit.I didn't check for speed. I'm not concerned about that since I won't be using the dock very often, maybe once (or twice?) a year. As long as it works, i can be patient if needs be.My only complaint is the location of the on/off switch being on the side where the cable plugs in. It's a wee bit awkward to reach.Update: I just discovered this dock is TRIM compatible in Linux (I use Linux Mint) but you will need to created a udev rule to enable it. Here are the directions for creating a udev rule to enable TRIM compatibility in Linux Mint, etc.1. Verify the Vendor ID and Product ID.Run lsusb in the terminal with the device plugged in. If you aren't sure which device in the list is your SSD, unplug it and run lsusb again and see which device disappeared. (Don't forget to unmount the filesystem before you unplug it.)Every device has an ID value in the list. For example, the ID for this enclosure is “0bda:9210”. The Vendor ID is the first part and the Product ID is the second part. My enclosures have the Realtec chips in them.2. Create a udev rule. In the terminal, copy and paste this line and hit Enter.sudo nano /etc/udev/rules.d/50-usb-ssd-trim.rulesType in your password, then hit Enter again.Copy and paste this rule into the text editor (all one line; the correct IDs for this enclosure has already been added):ACTION=="add|change", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="9210", SUBSYSTEM=="scsi_disk", ATTR{provisioning_mode}="unmap"Pressing CTRL+O, then ENTER, then CTRL+X will save and close the file in Nano.Now, the next time you plug in your device via USB, TRIM should work.

I like that this thing runs very fast for what it is. Don’t have to put any tools to it to put the SSD in and out and it always runs cool. I’ve had a lot of problems with overheating my SSD’s since I got this which has been almost 2 years now and I clone my pc to this every single week over a terabyte and I don’t have any problems with overheating. When I was cloning my drive and it was 930 GB it used to take about 24 minutes to copy. Now that I’m getting close to 1.2 TB on my computer it’s taking more like 34 minutes to copy it. I have tried other enclosures that worked, but none as easy as this, you had to use tools and pull screws out to put drives in and out. If I was just using it for cloning my pc’s drive I would leave that drive in it, but I use it for other things and other drives. That would be way too inconvenient to have to take them apart to swap the drives and this is the first one with a fan that actually worked keeping it cool don’t think it’s ever gotten over 52c.Pretty soon I’m going to upgrade to the Graugear 40Gbps model seeing how my pc has usb 4 ports on it and will do those speeds. Wouldn’t think of buying any other kind.I also use good ssd’s I have 2tb samsung 990 pro’s in my pc and the enclosure. I’m surprised that it actually cools as good as it does because I can never even hear the fan.

I’m using this for external storage of PS4 games on my PS5, and while it has amazing read/write speeds (gameplay is absolutely flawless and blazing fast), it suffers from a fatal flaw: every time the PS5 goes into rest mode, it causes the drive to crash. An error will come up the next time it’s turned on warning that it was not properly ejected. If you turn the system fully off, however, no such problem occurs.The problem with this enclosure seems to be that it has an on/off button. The PS5 will initiate its own “safely eject drive” process automatically when powering down, preserving the drive. But when going spontaneously into rest mode, the PS5 tries to keep the drive engaged… and then the enclosure itself seems to shut off prematurely, causing the error.I love Graugear’s other PS5 gear, as it all is top notch quality (their heatsinks especially). I even got Graugear’s other SSD enclosure, and it works much better and without the same errors (likely because it does not have an on/off button and keeps the drive engaged in rest mode). I was forced to use this one because my own SSD has a built in heatsink and this is one of the only PS5 compatible drives with enough space for that.If you are using this for PS5 external storage and your SSD does not come with its own integrated heatsink, then please buy Graugear’s other enclosure; it’s perfect for that. If, like me, you’re using an SSD with heatsink, then this is fully usable AS LONG AS you never let the PS5 go into rest mode with this enclosure turned on.I’m giving it 4 stars because this is a generally great product with a pretty minute technical limitation.
