Review on 💾 SSK Aluminum HDD Docking Station, USB 3.0 to SATA Dual Bay External Hard Drive Dock, Caddy Reader for 2.5 & 3.5 inch SATA HDD SSD, UASP Offline Cloner/Duplicator Function (2x16TB Supported) by Maria Fukushima

Revain has several devices with the same functionality from different manufacturers. I've made at least one of almost every device. Of all the devices currently available at the time of writing this review, this one has the best build quality for the price. I have both one piece and two piece blocks. This device and several similar dual-bay devices enable offline hard drive cloning. I clone a lot of hard drives at work, but I've never tried it without a computer and software. Most of the time, I clone a PC's mechanical hard drive to an SSD to upgrade it. The offline cloning feature requires that the target disk has the same or larger capacity than the source disk. With the right software, you can clone anything from a larger capacity source drive to a smaller capacity destination drive. As long as the data on the source disk matches the destination disk. It can be cloned and used as an operating system boot disk. I use OS cloning software from 2TB HDD to 1TB SSD and from 1TB HDD to 500GB SSD. Of course, this device can be used as a docking bay for the target drive during the process, but the same can be done with a single bay docking station. I use this model and other models with one or two target drive bays. There are reviewers who have successfully used this device and similar dual bay docking stations for offline cloning. This is not the method I use. Even without using the offline cloning feature, these devices have many uses. I've never used a brand/model that didn't work properly for my needs and this one works great. I see various reviews indicating that data transfer speeds can be both good and bad. This issue has more to do with the read/write speeds of the drive itself and the speed of your USB 3.0 vs 3.1 speed than the docking station. I can assure you that when using a modern SSD and the USB 3.1 standard, this docking station can easily meet or exceed the advertised read and write speeds. Reading all the claims of speed or no speed, remember that there are mechanical hard drives on the market that cannot reach USB 3.1 speeds even when connected via SATA. You won't be magically accelerated over USB, regardless of the docking station's capabilities.
