Premium Functions Supported
Hot Swapping - This USB 3.1 Gen 2 hard drive enclosure can be inserted or removed without turning off the power and will not burn the host or peripheral devices, also can be detected in time.
TRIM(computing) - Allows an operating system to inform a SSD which blocks of data are no longer considered to be 'in use' and therefore can be erased internally. Trimming enables the SSD to more efficiently handle garbage collection, which would otherwise slow future write operations to the involved blocks.
S.M.A.R.T (Self-monitoring Analysis and Reporting Technology)- When S.M.A.R.T. data indicates a possible imminent drive failure, software running on the host system notify the user so preventive action can be taken to prevent data loss, and the failing drive can be replaced and data integrity maintained.
Auto-sleep Mode - No operation within 3 mins, this hard drive enclosure will enter Sleep Mode to decrease the hard drive power consumption and any data transfer will wake it up at once.

I did a few basic speed tests using an ADATA SU750 1TB, which is not a rock star of a drive compared to others. I had no problem getting very good speeds and it is easily 4 to 6 times faster than many good USB sticks out there. Speeds did occasionally drop, (which was expected) but it is still very acceptable. Drops like this are always from the SSD' cache limit and have nothing to do with the enclosure. You get what you pay for with SSD's.
Real world copy test
Using a USB 3.1 Gen 2 cable and copying 20GB folder with files ranges from 2GB to 1MB, speeds were:
Internal NVMe SSD to USB 3.1 Gen 2 SSD = Read speed 440MB/s to 120MB/s, Write 260MB/s to 80MB/s
Internal Sata SSD to USB 3.1 Gen 2 SSD = Read speed 330MB/s to 90MB/s, Write 140MB/s to 80MB/s
This enclosure does what it's supposed to do, and the results were what I expected. I can always swap out a SSD easily and get better performance buy simply buying a better SSD. USB Gen2 is something everyone should be able to enjoy. It saves you a ton of time for backups. Sadly, many computers (mostly laptops) before 2020 don't have Gen 2 ports. But if you do, use it and enjoy something that is future proof for a long time.
I liked this enclosure so much I bought two of them and designed a 3D printed holder for them.

I agree that it is hard to remove the SSD once connected. For the good, the connection is very secure. For the solution, just insert 2 small slot screw drivers gently and the SSD will come off. I only use my fingernails.
However, removing the cover is a bit tricky. It is not difficult to remove, but you push down too hard, you may one day break the cover.
Now the performance:
I have 2 old SSDs, both sata and 250gb, one from Crucial (BX2) and one from Samsung (EVO250)
I connect them to my computer through different ports (using only the OEM cable), and achieved very different results.
Copying 20G to the enclosure:
Crucial--
thro the front USB3.0 port - 348MB/s for around 2G, then dropped to 54MB/s
thro the back USB3.0 port - 320MB/S for around 2 G, then dropped to 54MB/s
thro a Ugreen C to 3.0 hub - 318MB/s for around 2 G, then dropped to 83MB/s
thro a 10-year-old USB3.0 PCIe card - 100MB/s all through
Samsung--
thro the front USB3.0 port - 365MB/s for around 3G, then 100MB/s
thro the back USB3.0 port - 322MB/S for aound 3G, then 100MB/s
thro a Ugreen C to 3.0 hub - 325MB/s for around 4G, then 100MB/s
thro a 10-year-old USB3.0 PCIe card - 100MB/s all through
Seems like temperature of the controller inside the enclosure is affecting the performance (cannot verified). Otherwise I got around 100MB/s sustained writing speed. Since the enclosure can provide 300+MB/s for 2 to 4 GB writing, it is quite good for writing files smaller than that size.
Reading speed should be higher but I didn't test it. I use the enclosure to back up files only.
For durability, it will take time to tell.
For the price, product recommended.
Drive used: Silicone Power A58 512 GB SSD.
Installed in the computer it got sequential Read / Write speeds of:
Read: 497.43 MB/s
Write: 464.02 MB/s
Using my USB 3.1 GEN 1 type A port (and a generic USB-C to USB-A cable) the Seq read writes were:
Read: 37.78 MB/s
Write: 42.25 MB/s
Using my USB 3.1 GEN 1 type A port and the included UGreen USB-C to USB-A cable the Seq read and writes were:
Read: 397.61 MB/s
Write: 414.02 MB/s
Using my USB 3.1 Gen 2 type C port and dual ended USB-C cable the sequential read and write speeds were:
Read: 430.29 MB/s
Write: 463.21 MB/s
As for real world testing, I copied over 55 files totaling 17GB and results were loosely as follows:
- USB 3.1 GEN 1 type A port using included UGreen cable, transfer write speed was hovering around 393 MB/s for about 35% of the transfer, then dropped to around 100 MB/s, at times dipping as low as 68 MB/s for the remaining 45 seconds, or 65% of the transfer. I don't know if this is an issue with the drive, enclosure, or Windows 10
- USB 3.1 GEN 2 type C port using my own type C to type C cable, transfer write speeds were similar to above. Staring off with high 300s and then dropping to 68-100 MB/s after 30% mark.
I don't usually transfer such large files, but did it for the sake of this review I threw something together.
So, YMMV.
My UGreen enclosure looks different than pictured. It's got a clear plastic top, and absolutely no branding anywhere on it. For all intents and purposes, I have no idea who makes this enclosure or the model. I only know it's by UGreen because it came in a UGreen box with a UGreen cable. Then again, my Orico clear plastic enclosure doesn't have any branding on it at all either.
Top reviews from other countries

On USB3 the Buffalo enclosure speed drops slightly, so I was expecting this UGREEN to be similar and certainly not match the Thunderbolt performance.
However I'm stunned to say that with the SSD installed in this UGREEN enclosure, I was getting 420MB/s sustained speeds on a USB3 (Gen1 ie 5Gbps link) so clearly excellent.
One down side from my perspective is that the cable supplied is USB-C (enclosure end) to USB-A. I was expecting USB-C at both ends so now have to source another cable. Not the end of the world but does add unexpected cost.
BUT: when using this with a new Mac mini ie Gen2 USB3.1 (10Gbps) it was terrible. 15MB/s on the USB-C ports and unreliable / disconnects etc. on the USB-A ports. I was going to send it back, but then I bought a decent USB-C to USB-C cable and it absolutely flies with that - getting over 500MB/s sustained speeds.
I can highly recommend this enclosure if you're looking for something that will perform really well on USB 3.x and you're willing to pay for a decent cable. However it's a bit of a compatibility nightmare with the cable that's included hence only 4 stars which is a shame as this is the fastest enclosure I've ever had, bar none, once you spend hours sorting through the cable problems!

I use a 750GB MX300 SSD with the caddy for my Dell XPS 15 9570 since I only have 500GB on my laptop. I store games on it since a lot of the newer ones are 50GB+. There has been no slow downs or performance issues with playing my games off the external SSD.
I have attached images comparing the speeds of the SSD when: it was in my PC (via SATA), connected to my laptop via the supplied USB-C to USB-A cable and connected to my laptop via USB-C to USB-C (bought separately). As you can see there isn't much difference between connecting it internally and using a USB-C to USB-C. I was worried that the performance of the SSD might be bottlenecked by the caddy but it is not the case.
Overall, I would recommend this to anyone looking to put an external SSD into it, just make sure you get a decent USB-C to USB-C that supports at least 5Gbps of file transfer.

1. TRIM - ensures you get maximum life & performance from your SSD
2. USAP - increases speed over USB 3.0 connections
3. USB 3.1 Gen 2 - combined with USAP means this enclosure has a faster connection than most SSD drives available today need. It supports speeds up to 10Gbps whilst most SSD drives can only get to around 4-6Gbps, which is 500-750 MB/S - confusing I know as SSDs are all compared on MB/s (Megabyes per second) but USB standards are quoted in is Gbps (Gigabit per second) - TIP: if you want to find our the conversion for your SSD speed just google "mb/s to gbps" and you'll get an online conversion tool.
I'm getting real world speeds on my Samsung Evo 850 1TB drive connected to an iMac thunderbolt/USB 3.1 port of Sequential write of 456 MB/s and reads of 513 MB/s. The official specs for this drive are 520 MB/s write and 540 MB/s read but from what I understand from reading online reviews is you never get these speeds in real world situations.
It's great value for the price as I saw some enclosures that were 2x or 3x the price for the same spec. To make sure you get the best performance from the drive make sure you get a good quality USB 3.1 Gen 2 cable that can support the 10 Gbps speed and if you're using a Mac then you will have to get your hands dirty with some simple Terminal commands to turn on TRIM or download one of the TRIM enabler tools available online.
My only one criticism is the drive comes with a USB C to USB A connector but to hook it up to a fast USB C/thunderbolt port on a Mac you need USB C to USB C cable - would be great if they offered a different version with this cable like some of the competing drives, but it still works out good value if you add in the cost of a £10 USB cable.

Maximal kann die Samsung 850 Pro 550 MB/s.
Ganz wichtig sind die Kabel. Das beiliegende funktionierte bei mir einwandfrei.
Das Gehäuse hat einen USB Typ C Anschluss.
38 MB/s -> USB 2 Kabel Typ A oder C
412 MB/s -> USB 3.1 Kabel Typ A
495 MB/s -> USB 3.1 Kabel,Typ C
Um das Optimum aus seiner Festplatte/SDD rauszukitzeln benötigt man daher:
- Gehäuse mit UASP und USB 3.1
- USB 3.1 Kabel, am besten USB Typ C auf Typ C
- Kabel sollte min 5 GBit/s unterstützen, nicht 480 MBit/s!
Ein Gehäuse (von Anker) ohne UASP lieferte nur 235 MB/s!
