ACASIS 20Gbps M.2 NVMe SSD Cloner & Docking Station, Dual-Bay Duplicator

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

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.

I go through internal storage devices frequently because I do a lot of video work. Mechanical hard drives fail over time, SSD's fail over time and NVME's fail over time. This device I purchased on a lighting deal through Amazon. Absolutely no regrets. It cloned my NVME (Source) to NVME (Target) in less than 15 minutes. I paid an online service about $48.00 bucks to do the same thing in the recent past. I am about to purchase a device that copies SSD's to NVME storage devices. So worth it and it will save you money. I recommend it. Yea it heats up, but not like the Apocalypse or Armageddon like other reviewers decribed. I recommed this product. I am not getting paid or compensated for this review. Just buy it. It is built like a tank. That I agree with.

Does not work out of the box. Identical M2 drives... both can be recognized but it refuses to clone. Also runs hot.

Worked well,except when i tried to copy direct to drive, but was fine cloning from drive installed in macine to new very happy with prchase.

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.

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.

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.

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

Worked flawlessly. I wish they added hdd to SSD copy option

Super easy drive cloning, one button.

初めに手に取った感想は、「小さい！」、「カッコいー！」です。 これだけでも購入する価値あります。笑 ソース側に差し込み、USBでパソコンと接続し動作確認。問題なし。 次にターゲット側に差し込みましたが、パソコンにマウントしません。 これは仕様だと思います。 そしてクローン。 ソースに元SSD256GB（データ容量100GB位）、ターゲットに新SSD2TBでクローンボタンを押してスタート、、、え？何かした？ 2分位で、100%になり点滅から点灯になりました。 とりあえず、2本共外して、新SSD2TBをソースに差し込みパソコンでマウントさせてみました。 ホントに256GBでフォーマットされてデータも入っているよ。 あまりの速さに「えーーー」ってなりましたが、パソコンに差し込み起動してみたら、しっかり起動しました。いつの間にコピーしたの？って感じ。 ホントにマジックの様な素晴らしい体験をする事が出来ます。 HDDからSSD2TBのクローンなんで数時間から6時間位掛かるので本当に驚きました。

写真ではチ－プな印象でしたが実際物を手にしてみるとズッシリしていて高級感がありとても満足しています 後クロ－ン速度ですが250Gを1分足らずでコピ－出来て爆速にビックリしました、
