UGREEN Hard Drive Enclosure, USB 3.0 to SATA HDD Caddy for 2.5 3.5 inch SSD HDD Disk up to 22TB with DC Power Adapter, Tool-free Lay-Flat Hard Drive Docking Station for Windows Linux macOS, PS4, Xbox

I had very specific requirements which led to me purchasing this, but in short the main reason I got it is because it was the only SATA mount I could find on Amazon that was mains powered rather than bus powered.This was essential because I have a 2011 iMac with the now redundant Thunderbolt 2 port. These ports do not supply bus power, so if I wanted to take advantage of the higher speeds of Thunderbolt 2 (via an adaptor) and use modern SSD drives, I needed something like this. The plan worked.The unit itself is quite large, owing to the fact that it also accommodates both 3.5" and 2.5" drives. I only use the smaller size SSD drive, but this actually means there is more air around it so aiding in cooling. It's all very simple to assemble and it's plug and play. No technical expertise is required, it's no more complicated than setting up any kind of disk drive from the olden days!It comes with a 12v mains supply (with 13amp UK plug on the one I bought here in the UK). There is also a USB 3 cable - configured with USB-B on the unit side and USB-A to plug the device into a computer (or in my case a Thunderbolt 2 adaptor). There is power button and a blue LED to indicate the mains power is on.I'm not a very technical person in terms of specs and benchmark tests etc, and I'm sure there are other reviewers who will provide that data. Suffice to say, there is a noticeable difference in the speed of this setup compared to the old HDD I had plugged into the slow USB 2 ports on the iMac.Essentially I've upgraded an old mac to a modern standard. (I'll also be replacing the internal boot drive with an SSD, but that's another story).Another benefit of this, is that I can switch out the SSD drive I bought with it to other drives. For example, the old internal HDD drive I'm taking out of the Mac, can now be used as an external drive for backups etc. If I need to buy more SSD drives in the future, I can save money and just get internal SATA ones rather than the more expensive USB-C external drives.All in all, I'm really happy with this set-up. I've revived an old iMac which was on the verge of redundancy, and have given myself lots of neat options for future memory expansion. And it wasn't exactly expensive!

Fantastic enclosure and really easy to set up

This is a great accessory at a good price. Fast data transfer and solidly made. Just a couple of niggles when it comes to actually using it. The power light is far from bright and in a sunlit room I have to cup my hands around the light to make sure it is off before disconnecting. Second niggle - the lid doesn't have a positive enough catch when it is slid closed so picking it up the wrong way can cause a heart stopping grab as you stop the drive sliding out of your hand. Good buy though.

This UGREEN Hard Drive Enclosure, USB 3.0 to SATA HDD Caddy for 2.5 3.5 inch SSD HDD Disk has actually amazed me. I had some 2TB external drives that I could not access (literally for years) and could not see them when connected to a PC. To my total astonishment they were instantly accessible when inserted into the UGREEN drive caddy. I had approached a professional DATA Recovery company and they wanted £600.00 per drive to recover data and all my DATA is now fully recovered! I am elated with this result as it has saved me an enormous amount of money and I have access to DATA that has more than financial value.I cannot say everyone will get the same result as I did although I would hope that they will. I strongly recommend this product and I don't think I'll need to buy again as it seems quite sturdy and well designed and I would not hesitate to recommend it to others.

I bought a 1TB, 3.5" Seagate HDD at a car boot sale for £3. Luckily it worked and initially I used it with a generic HDD harness, which did the job but wasn't pretty, what with the unused connectors left dangling from short, untidy leads. Also it left the drive itself exposed. (Besides I usually use the harness to connect an internal optical drive to my laptop, so I needed it back.)I transferred the HDD to this handsome enclosure - which was laughably easy; no tools required - but found that Windows now wanted to format the drive. I've no idea why. In the end, I had no choice but to obey having by now shuffled the data I'd already loaded on to other drives (by temporarily reverting to the harness). Even then, for some reason Windows only gave me access to about an eighth of the full capacity; this problem I fixed by using the partition manager application to extend the one partition into the inexplicably unused space. This may be a problem with Seagate drives.Anyway, I now have a 1TB drive for about half the usual price. Even if the HDD breaks down, I can always use the enclosure with another HDD.I must say I find the enclosure exceedingly neat and appealing-looking; even the power/activity light is a pleasing colour and not obnoxiously bright (which makes a change these days; just because LEDs are bright and efficient doesn't mean they always have to be driven at their full brightness!).It does indeed work with USB 3.0; the transfer rate is much better than I'm used to.So, this is highly recommended but beware that Windows might make you format the drive once it's in the enclosure. Plan accordingly! Either start with a drive you want to format anyway or be prepared to take a back-up. Hopefully you won't have this problem at all.
