I have what is considered a poor man's RAID configuration -- a primary hard drive that is mirrored regularly to another drive. Since external drives tend to be more expensive than internal ones, I bought this hard drive bay so I could treat internal drives as external. I can also continue to swap out drives with larger-capacity ones like they are game cartridges. This is a much cheaper option than an actual RAID enclosure and doesn't require any advanced software or configuration. Keep in mind that the operating system will treat the drives separately with their own drive letters. It's up to you how you want to use the space.I did a little test and found that using the manual driving cloning feature is no faster than using a software-based backup app to mirror data between one drive and the other. Don't buy this thinking that it will rapidly clone multi-terabyte drives in minutes. It takes hours to clone the drives. Also, if your destination drive is larger than the source one, that additional space will not be partitioned. But you can extend the partition with free software available on the internet.Honestly, this doesn't offer any more functionality than what I could get with a SATA-to-USB adapter and some backup software. But it does look nicer and reduces the number of cables I need to hook up multiple drives. It's convenient if you have multiple drives that you are regularly attaching to your PC or are looking for an easy way to duplicate data between two physical drives.

I keep backups of my PC on my Synology NAS. I also keep backups of the NAS to External HDD for offsite storage in case of disaster. I decided to use the docking station to make the my copies for offsite storage on bare HDD and just keep them at my relatives. It didn't work at first until I found my mistake.I used Synology USBCopy to transfer the files from the NAS to the dock HDD. I missed unchecking the Eject after Task Completed box in USBCopy. After sending the first file to the dock, the NAS software ordered the dock to eject which caused subsequent file copies to fail AND apparently corrupted the file so the NAS always thought the task was completed if I tried to rerun it. After unchecking the box, everything works perfectly and this is a lot cheaper than buying external USB drives.

I had used a similar product of another brand years ago and it damaged my HDD. I stayed away from such products for a while. Now I found this brand.This one is made well. I like the USB3 Type B connector. It is rugged and supports reasonable speeds. I now use it to sync up my external drives for backup/archival. I use a combination of SSDs and HDDs.Used it only a couple of times but works well.If I had to pick a problem with this product, it is the easy access to the clone button in the front. It hasn't happened to me (yet) but I fear it is easy to press it accidentally. I plan to use it only once. After that, I will put a flat hard plastic piece over it and tape it up.

SABRENT USB 3.0 to SATA I/II/III Dual Bay External Hard Drive Docking Station. I've purchased one years ago that is a dual docking station, and it still works great. So that's why I've decided to purchase this new one which is even better since you can copy HHD or 2.5 SSD with a push of a button.I use these to make backup to an external hard drive, so I can take them to another location for safe keeping and install another HHD for the next backup. Works flawless and makes your job easy so that you don't have to purchase expensive 2TB or 4TB external drives, and have to unplug etc. The HHD are in a cool plastic HHD case with dates on them. Would buy again and recommend this product for home or server uses.

I've been using the Sabrent USB 3.0 to SATA External Hard Drive Docking Station for about two weeks now, and I'm generally pleased with its performance. I replaced my old SSK dock with this one after it failed within a year, and so far, this Sabrent dock has been a more reliable choice.The speeds on this dock are definitely an improvement over my old one. I've connected my Synology Disk Station to the dock via USB, and I've achieved transfer speeds of up to 120 MBps. Response times are also snappy, making it easy to transfer files and data.While I haven't had time to thoroughly stress-test this dock, it's been working smoothly so far. The power delivery seems stable, and my hard drive has been running without issues. I appreciate the compact design and the fact that it's easy to set up.Overall, I'm glad I made the switch. This Sabrent dock is a solid upgrade from my previous one, and I'm hoping it will last longer. If you're looking for a reliable USB dock, this one is definitely worth considering.
