ACASIS NVMe M.2 Duplicator, M.2 ssd cloner Dual-Bay Offline Clone, USB C to NVME Docking Station for M2 SSD M Key Hard Drives Enclosure

Work perfect, that’s what I was looking for, cloning in less than 10 minutes , easy to use , connectivity make sure to connect both sides properly before use & download cloning software to your pc

I wanted to get one of these so i can make a generic windows image and clone it from SSD to SSD. But the it says it can copy images to both SSD slots at the same time as well as read off both at the same time. Not sure how that works as i haven't tried it yet. But the unit is pretty small, it's like 2" x 3" and maybe around 5/8" tall? The top has two M2 slots that face up. The device has a usb-c slot and comes with two USB cables, one with another USB-C and one with USB-A for your normal usb slot. So connectivity is easy. The cables are sort of short, just over 8-10" long for both usb cables, so if you only have access to the back of your computer case, you might want to buy a USB to USB female extension. The power cable looks like a standard power supply and two prong plug. Next to the power jack on the side of the unit is the on/off button, so use that once you plugged in the one or two SSD's. There is one button on top, which allows you to do SSD to SSD copies like upgrading a 1TB to 2TB ssd, which is great. The source slot is the one closest to the on/off switch, and the target slot closer to the clone button on top of the unit which does this offline so you don't need the USB cables if just doing this. So overall, the unit is small, it's housed in like an aluminum housing and feels solid. Overall, i like the quality and will write an update if i ever have any issues cloning or other failures.

What is the point of advertising your product to support something when it actually can't?I got this cloner to make a copy of my M+B Key SSD to my M Key SSD. The device can read my M Key SSD fine, but the M+B Key SSD is unrecognized. And I can verify that it works: it literally was previously on my computer and isn't even a year old.This was a waste of time and money. I recommend this listing get taken down for false advertisement.

Works as it should

It worked after the 4th try. I tried offline cloning exactly per instructions to no avail several times. The likely trick is to initialize or format your brand new m.2 NVMe before cloning. That and contrary to the precise interpretation of the instructions, DO NOT hold the Clone button down for 3+ seconds UNTIL all the progress lights start flashing. Just hold it down for 3'ish seconds AND RELEASE as soon as all 4 lights power up; they will start flashing in less than a second as intended. If you hold it until they start flashing and then release (as instructed), it for some reason appears not to work. So the cadence to I found successful to use is: 0) Initialize the target disk if possible 1) insert source disk 2) insert target disk 3) plug in power cable to cloner 4) push power button 5) wait for the 3 side blue leds to light up indicating drive recognition 6) Push and hold the Clone button for 3 seconds JUST until all 4 progress leds turn on, then let go. 7) Observe/confirm the progress leds are all flashing and wait for them ALL to stop flashing indicating process completion (clone time depends on drive size/speed). 8) Once all 4 lights are on/static, press the power button to turn off 9) unplug power cable 10) remove drives and install Target drive as planned. As directions state, you will likely need to "extend drive" in Computer Management to recoup any unallocated space from a larger target drive. A WORD OF CAUTION: This device begins to excessively heat up once plugged in; even with no drives or activity running. Do not leave it plugged in when not watching it. Do not leave your M.2 in for any longer than required. My Laser Infrared Thermometer recorded the device surface at 143+ degrees F during operation and again after a cool down and no drives installed. The top-end safe heat range for an M.2 drive is around 158F; too close to potential damage for my liking on a new 2TB 990 Pro. It may not be a fire hazard, but I'd treat it like one for due diligence since it heats up at all times. Or mine does.... However, once it works, it's great. Have done a couple drives now so happy with the purchase. Pricey for a cloner compared to cheap m.2 cases but way faster than via USB cable.

Got this unit today, and it works as an external drive just fine. With a pair of M.2 NVMe drives loaded in it, you can see both drives just fine.The stand-alone clone is trickier.I watched the videos and followed the instructions on this page, and it just would not clone. Pressing the clone button until the lights start flashing just sat there and did nothing. I did not have it connected to a computer, before I cloned I did verify that both drives would show up on the computer. I did a scan on both drives and there were no issues.I then found the user manual (which is not included in the packaging), and looked it over. The instructions there were to press and hold until the light flashed, then release and press the clone button again. Now the lights are flashing a different pattern and the clone worked. I then checked out both drives on the computer, and it did a fine job of partitioning the new drive with the recovery partition and a couple of other partitions that were on the original drive, and all is well.I took off one star and gave it only 3 stars on Tech Support for having incorrect instructions and not including the user manual with the packaging (only the user guide was included and it also had the wrong instructions.The unit does get quite warm while it is on, even when nothing is happening with the drives. I would suggest not leaving it unattended or overnight with it on. Also, you really should put it on a surface that will not melt or burn.It works very well, once you get to know how to use it.

Cloned a 2TB M.2 to a 2TB M.2 and it worked just as described.Because of the reported heat issue I attached it to a Xnrtop Aluminum Heat Sink, using Easycargo Thermal Glue. No heat issue at all. It worked fast and I am happy. I also bought a pair of 30mm fans to cool the heat sink, but they were not needed.Kudos to the inventor(s) of this product.
