SSK Aluminum Hard Drive Docking Station, USB 3.0 to SATA Dual Bay External HDD Dock Caddy Reader for 2.5 & 3.5 inch SATA HDD SSD, with UASP Offline Cloner/Duplicator Function (2x20TB Supports) Black

Works well and seems to have a consistent connection to the computer, unlike some others I have tried. Speed is good. Unit is nicely compact. I did not test the "cloning" feature.

Note that this hard drive docking station is of usb version 3.0 so it is not as fast as others of version 3.1 or higher. Nevertheless, it is fast enough for the docking station to provide access to up to 2 hard drives to your system. The hard drive can be a 2.5 in or 3.5 in. Just dock the drives to the 2 slots and connect the usb3 cable and you're good to go. The dock station has a copy function to copy from one drive to the other. Just make sure that the disk space are large enough for the disk copy process. I like the fact that the dock station goes to suspend state when idle and will rev up your drives when accessed. Nice product.

Used on newer ssds, old 2.5 and 3.5 hdds on windows 10.11 and Ubuntu 24.04. Only issue is with slower drives. Takes 5-10 minutes to be accessible. I assumed that they weren’t going to work if it took more than the advertised 20-30 seconds to see a disk.I didn’t try the clone function, no real need when there are easy software solutions

sturdy construction and easy to use

I used this drive for about 8 months with just 1 drive in it and it worked really well. It's on a machine that never reboots unless the power goes out for an extended duration. In those 8 months the single drive corrupted entirely once when the power failed. I chalked it up to the failure.About a months ago I put a second drive in the dock. In that month I have lost both drives three times... Again, once when power failed... I blamed it on that again... but the last 2 times the drives and data were working fine and upon a normal reboot the drives simply come back up as inaccessible. 99% of the access to these drives are READING for my media server. I have 2 other USB drives on this machine and they never corrupt. There are 4 internal hard drives that also never corrupt. It's only media in this dock... no other corruption issues whatsoever except this device.So, it seems with 2 drives installed, a reboot is very likely to corrupt both drives.I will now enter my 3rd recovery phase on my drives because of this dock after I rebooted my computer tonight... where I likely, again, will not get back 100% of my media and will have to go to backups.I highly recommend passing over this dock. It's caused me a ton of frustration.

I was skeptical at first, since this is my first time using an offline cloning device. I wanted to clone 4 drives from my Synology NAS which are in a RAID configuration. The first 20tb Seagate EXOS x22 drive cloned to an identical blank drive took about 24 hours. The resulting cloned drive works perfectly within the old array - the NAS didn't notice anything different. So, this is definitely a bit-by-bit clone, including all unsused space, down to the last bit on the platter. It doesn't matter what OS, partition, RAID, or format your source drive is - it seems to be a perfect copy.While copying, the drives are no longer inside an air cooled enclosure such as your PC case or NAS, so they do get hot. I found and stuck a small usb portable fan beside it to help bring down the temps.The unit isn't made of plastic, as you would expect. It's actually metal. Aluminum, maybe. It's got a nice quality solid feel to it. Overall, I am very happy with my purchase.

Plug and play ease of use! Exactly as described.It was as simple as connecting the power, usb, and my two hard drives. No issues.

I just used it to copy a spining 500 gb hard drive to a 500 GB SSD and pushed the buttons and walked away.I Stuck the SSD in the computer and it took off just fine (Only a lot faster)so it worked just fine.
