UGREEN External Hard Drive Enclosure for 3.5 2.5 Inch SATA Drives, Tool-Free USB 3.0 to SATA SSD HDD Enclosure with 12V Power Adapter, Laptop Computer Hard Drive Case Support UASP and Trim

This product is a simple, excellent common-sense device. Insert your disk, connect to the computer, and power, and you are all set. It is as simple as inserting a flash drive.

This is by far the best enclosure I got for my TB external drives. Very easy to install and plug & play. No issues whatsoever till now. The sleek look is much better than WD & SG drives.

This UGREEN External Hard Drive Enclosure for 3.5 and 2.5 Inch SATA Drives (no model number given) is an attractive product not particularly bigger than a standard 3.5" SATA III hard disk. The plastic material is of good quality. It is not unduly difficult to open the cover and insert a 3.5" HD. There is a power switch, USB 3.x Type B port (I prefer the Type B connection for this type of enclosure) and a power port.A first consideration for such an enclosure is that it be compatible with HD(s) that are partitioned and formatted in a desktop computer by a standard SATA III port. For this to occur it is *required* that a small "reserved partition" be found by the OS at a particular offset. If the reserved partition is not found at this offset one may be advised that the HD needs to be partitioned and formatted. If the drive is partitioned and formatted data on the drive will be inaccessible and very likely lost.I'm please to report that two WD Black SATA III HD(s) (4TB and 10TB) partitioned and formatted NTFS in a Windows 10 desktop are fully compatible with Windows 10 as installed in the UGREEN enclosure and compatible with macOS Monterey to the extent anticipated. macOS Monterey will only read but not write to an NTFS formatted HD. Furthermore a 1TB Hitachi SATA III HD formatted in the enclosure by the macOS Disk Utility in the exFAT format is fully readable by Windows 10.The ASM225 chipset seems to have excellent compatibility with my SATA III HD(s). In the case of the recent WD Black HD(s) S.M.A.R.T. data is transmitted to both Windows 10 and macOS Monterey.Spinning a hard disk 24/7 that is not designed to spin 24/7 is quite undesirable. The information presented here is that the HD in this case will automatically spin down after 15 minutes of inactivity. This checks out in Windows 10 but macOS Monterey seems to capriciously spin down the HD more frequently. In the System Preferences (Monterey), Battery section I've set ( ) Put hard disks to sleep with possible to off. I'm not sure why the macOS is spinning down the HD but I'm sure this is an issue with the macOS and not the UGREEN Enclosure.Spinning down an HD too frequently places ware and tare on the HD so frequently spinning down an HD should be avoided. Spinning down an HD in 15 to 60 minutes is recommended. An HD should spin down when ejected and when the computer is turned off. The OS may spin down an HD when the computer goes to sleep. This UGREEN enclosure checks out here perfectly.There are a couple of flies in the ointment concerning this enclosure. While there are ventilation slots in the bottom and along the sides of the enclosure there is no ventilation openings provided in the top cover so convection air flow and convection cooling will not occur. What appears to be small holes in the cover are just a texture variation in the plastic. If this enclosure is used in a warm environment the top cover should be slipped off to allow cooling.The tool free design is OK for those who prefer it but a moderately sharp rap on the case may disconnect the HD from the internal SATA connections. There is an outside chance of data loss. I dropped the enclosure in the original box it was shipped in a short 18". The HD inside partly disconnected from the SATA port inside. To avoid this problem, holes for optionally securing the HD with screws should have been provided along with a packet of 4 screws. Worse is the case of a 2.5" HD or SSD where nothing secures these drives but the internal SATA port. I strongly recommend NOT using this UGREEN Enclosure with either a 2.5" HD or SSD if the enclosure is to be used as a portable device. If the UGREEN enclosure is to be used as a dock only with the cover off on a desk then there is no need for screws to secure an HD of SSD.I'm giving the UGREEN External Hard Drive Enclosure for 3.5 2.5 Inch SATA III Drives 4 stars and recommend it noting the lack of ventilation in the top cover for use in a warm environment and the lack of holes in the bottom for optionally securing an HD or SSD for portable use. After checking out this UGREEN Enclosure I purchased a second unit.I hope this review is helpful.

You know how routers have a USB socket so you can access and external drive through the network? That doesn't work if your external drive is powered through the main data USB connection.The solution?This! If you want external drives to work seamlessly on your router, make sure it's independently powered, like this one.

Theoretical and real world performance can sometimes be drastically different. But despite not being able to hit those theoretical speeds, this is more than adequate for my needs.There is an updated version which is almost twice the price... which is kinda a hard sell considering performance honestly wont be that noticeably

Very simple to use and perfect if you do not need active cooling of your drive. I used it to clone my slow drive from my laptop onto my new ssd that I then installed in the laptop.

Like the title says: enclosure controller died after 11 months of use. Just dead: no power to SATA connector, no power to "On" light ... nothing. There's a reason this product is no longer available on Amazon.

First impressions after using it for a few hours: very basic but gets the job done. It's a plain black plastic box with USB and SATA connectors, a power button, a power/activity light, and nothing else. Slide your SATA drive into the internal connector, plug in the power and USB cables, and away you go.The USB connector seems a little nonstandard, so I'm not sure if you could use another cable than the one they give you, which is only a couple feet long.One big caveat is that the only thing that holds the drive in place is the friction-fit of the SATA connector; other than that it's just sitting on the bottom of the box. They didn't bother with any of the mounting screws that usually are used with a SATA drive (which is what makes it "tool-free", I suppose). That friction fit is pretty tight, but still, if the drive came loose while in use it'd be very bad for your data. This leads me to think that you only want to use this box for an SSD drive not a mechanical HDD, because any vibration from an HDD might eventually cause trouble. Likewise, I can't recommend it for any application where the box will get moved or jostled a lot. I'm using it with an SSD that is just going to sit on a desk connected to a non-moving PC, so it should be fine, but nonetheless I added some masking tape to hold the free end of the SSD in position. Call me paranoid.Another caveat is that the ventilation holes in the case are few and small. Again, this is probably fine for a 2.5" SSD, which shouldn't emit too much heat plus there'll be lots of air space in the box. Otherwise you might think about getting out a drill and making a few more holes in the plastic case.On the whole, it does what it says on the tin, and as long as you use it for an SSD that you won't move much, these caveats aren't a problem.
