Caddy for external SATA M.2 Drive...

Hi all, I'm looking for a caddy for a spare SATA based M.2 SSD I have to add external storage on my SFFPC but I'm a bit lost. I have a spare USB 3.1 Gen 2 port on the back of my machine which I believe can do 10GBS? 

This is the SSD I have... https://www.amazon.co.uk/gp/product/B07KYDYKQP/

 

I know there have been a couple of threads on here about similar enclosures but struggling to find them.

Any recommendations greatly appreciated!

@eightarmedpet, Given my experience with WavLink I would recommend their SATA M.2 USB-C enclosure

Just throwing my 2 cents out there for perspective. USB-C enclosures that are only 3.1 gen 2, are only 10 gigaBITs per second, not gigabytes. I know this is a smart forum, but just for those unaware, here's what that looks like: some NVMe SSD's reach around 3.5 gigabytes per second speeds. Very quick! But, as stated earlier, USB 3.1 gen 2 are only 10 gigaBITs, which converted to GigaBYTES is only about 1.25 gigabytes a second for a theoretical speed, which is almost 1/3 the speed potential of NVMe SSD's. I edit videos for work and for me that is a difference I can see. Most people may not care, but if you want the max potential of your external NVMe SSD's, I'd use a thunderbolt 3 external NVMe enclosure. 

EDIT: Another small callout, if you do go external SSD thunderbolt 3 route, make sure you are using it on a separate Thunderbolt 3 chip than your eGPU! Some Macs have 2 titan ridge chips, like newer MacBook Pro's and 2018 Mac Minis that have their own bandwidth. For instance, if you have a 2018 Mac Mini and your eGPU is on the T3 port next to ethernet, make sure you use one of the 2 ports nearest the HDMI as to not divide bandwidth! Hope this helps!

SATA M.2 is only 6 Gb/s (~550 MB/s) so 10 Gbps (~900 MB/s) is more than enough for that SSD (lowercase b = bits, uppercase B = Bytes).

Cheers for the replies chaps... learn something new with everyone of your posts Joe... although that's not really that hard considering my depth of knowledge. 

Sounds like even with a normal USB enclosure (limited to 5Gb/s) I wouldn't be loosing much performance.
