UGREENHard Drive Enclosure, USB 3.0 to SATA HDD Caddy for 2.5 3.5 inch SSD HDD Disk up to 16TB with DC Power Adapter, Tool-free Lay-Flat Hard Drive Docking Station for Windows Linux macOS, PS4, Xbox

I have bought a couple of these caddies as they offer USB3 connectivity (think speed) to hard drives I've replaced in the past but still have useful service life as portables or backup drives.The caddies need no tools - no screws - all just push fit, look elegant and simply work.At sub £20 on Prime this is like legalised shop-lifting, and given the price of new drives they are a cheap and reliable and smart way of re-lifing otherwise useless bricks.

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!

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 is well made.It definitely powers on but I can't speak towards whether it actually works because it was meant to act as an external storage enclosure for an NVR but the NVR couldn't read the hard drive. I don't think this enclosure is to blame but rather the extra convertor cables I had to add on to connection, something might have gone wrong there.In the end I gutted this out, took out the electronics and made a gap to feed in internal wiring directly to the drive whilst it remained in the enclosure. I done this because even without the electronics, for me this would be the best non active 3.5 storage case that I have seen. My setup now works, and I have every confidence in the case protecting the hard drive outside of the NVR.I'd buy it again if I needed a single drive slot in an external enclosure. However, I will be looking and multiple drive slots next.

This is a step up on older HDD caddies of 10 years ago.It has an external power supply for better reliabilityVery easy to insert and remove HDDAll plastic construction but well made.Only used it for a short while, so reliability is unknown.Recommended so far

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.
