ACASIS 20Gbps M.2 NVMe SSD Cloner & Docking Station, Dual-Bay Offline Duplicator with Aluminum Heat Dissipation Enclosure, Tool-Free USB Adapter for M Key PCIe NVMe SSD Reader

Yes, the status lights are difficult to see in normal lighting because they are so tiny. But this is not a significant problem; it is just something for the manufacturer to improve on the next design. I used this to upgrade an Asus VivoBook S15 (Intel Core i5) by copying the factory SSD to a Crucial P3 Plus 4TB PCIe Gen4, purchased on Amazon, and it booted just fine. (I have 2 of the Crucial SSD sticks so I did this test twice.) The copy completed within five minutes and I did not notice any significant heat during the copy. The same test did not work when I tried to upgrade my older Asus VivoBook 15 using the same Crucial SSD sticks. The copy succeeded fine but, when either of the sticks were installed, Windows 10 would not boot. The factory SSD from the older Asus has two notches rather than one, so the problem might be that the particular SSD that I purchased is incorrect for that laptop.

Works perfectly, but the drives get super hot!!! It's best to unplug the unit as soon as the cloning is finished and let the drives cool before removing them from the unit. Other than that I am very pleased with the unit. Also, it will not clone a larger SSD to a smaller SSD, It only clones a smaller SSD to a Larger SSD

These types of devices almost always disappoint. They rarely work well. This one does its task. It clones a 512GB NVME in about 5 minutes. This is great for doing system testing and software installation test cycles, where you can't use a virtual machine. I have done over 10 clones without a single failure or error. It DOES get hot, but it is all aluminum and doesn't seem to be bothered. The LED lights give adequate status info for the purpose. You do need to use its included power adapter to do a clone; the thunderbolt connector didn't have enough power and it simply refused to initialize.

I have no idea how this got good reviews. I was able to clone 3 or 4 drives before it just stopped working. The cloning light would be blinking, but never complete the cycle. Also, this runs so hot that you can literally burn your fingers on it. I hate to leave bad reviews but I also hate getting ripped off. This sisn't worth buying. Waiting for a Startech cloner to show up. At least they have support.

This can be used as an auxiliary drive bay to read and write to M.2 NVMe drives as well as an off line one button cloner. It cloned a 256gb to 1tb drive flawlessly in leas than 15 minutes.

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.

This is an attractive unit, constructed well, doesnt feel cheap. I had to go to a clients office and clone a hard 500g hard drive. I was prepared for the process to take a few hours, but to my surprise it took about 10 minutes. It was able to clone completely independent of a computer, I.E. Just connect the two hard drives and press the clone button. The LED indicators keep you informed of the cloning process. It was quick and easy. I attempted to use this as a dock however it gets really hot. Luckily I caught it before it became an issue. So for me, this is just a tool to do cloning, and it does that well. It was worth the price based on its first use.

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.

本当に簡単にクローン出来ます！ Aスロットにコピー元、Bスロット(手前)に新しいSSDを刺して 左下のボタンを3秒長押しするだけです。 速度もかなり速く、大満足です。PC本体から取り外せるならこれで1発です。 ただし、暗号化(ビットロッカー解除)の解除をしていればです。

Me gustó el producto, es exactamente cómo en la descripción se plantea

Super easy drive cloning, one button.

クローン作りに必須。 簡単に作れてよい。しかもM.2 SSDは超早い。1TB、10分で完成

Se sobrecalienta demasiado y por lo mismo se interrumpe el proceso de clonacion
