NVME USB-C SSD Enclosure

Howdy,

I’m looking at picking up a 1TB Kingston A2000 NVME SSD and putting in an enclosure to use as a portable drive. My laptop is Thunderbolt 3 40Gbps/USB-C Gen 2 10Gbps compatible and the USB-C enclosure I have is USB-C Gen 2 10Gbps. The SSD is rated at 2000MB/s write.

What sustained write speeds could I expect with the A2000 in the enclosure? Am I correct in assuming I’ll be limited by the 10Gbps enclosure, giving me less than 1000MB/s?

Cheers

 

I can't even get close to that.
This is a transfer (a single 11GB zip file) from a 1TB Samsung 970 EVO+ in my Dell XPS15 9570 through the Thunderbolt/USB-C port to another 1TB Samsung 970 EVO+ in an Asus ROG Strix Arion ESD-S1C 10Gbps enclosure.
Not sure why it's so slow (the port on the laptop is Thunderbolt 3 / USB-C 3.1 Gen 2, so should do 10Gbps), but this is pretty normal for it.

 

Gibbon you should defintiely be able to get more: https://www.back2gaming.com/reviews...sus-rog-strix-arion-m-2-ssd-enclosure-review/

Might want to check if the drive is using UASP to get the best performance. Also check the link speed somehow? https://www.back2gaming.com/reviews...sus-rog-strix-arion-m-2-ssd-enclosure-review/

 

Thanks for the info. I also have an XPS 15 but the older 9550 with the same spec TB3 port.

I'm not sure how accurate benchmarks are compared to real world results? I just benchmarked my WD Black SN750 in my laptop with ATTO and it achieved over 3GB/s read and write, but when I copy and paste a large from from and to the drive it was only transferring at 850MB/s - Or is this because the drive was reading and writing simultaneously?

 

Yeah, I don't know what's going on with it. It's definitely in UASP mode, and USBView tells me it's "SuperSpeedPlus" - which I -think- is 10Gbps ... stupid confusing naming. This is what the top part of USBView shows me.
Not sure how else I can see the link speed?

 

Just ran ATTO on it FWIW. Quite different to that link earlier. Maybe it's the laptop controller.

 

yeh could be a range of things.

if you want/need higher speed then TB3 might be the way to go

 

I have a thunderbolt 3 drive enclosure somewhere in my "to sell" pile somewhere. I'll find it if anyone is interested.


Edit: here you go, it's a OWC Envoy Express. TB3 to NVMe SSD

I just stuck a 1TB Samsung 970 EVO Plus in it and it was doing 1172MB/s write and 1570MB/s read in Black Magic on a MacBook Pro.

 

Nice! No good for me at the moment though - I rarely use mine (so I haven't really been concerned with the speed), and when I do it's to transfer bulk data between my laptop and desktop faster than over wifi - and my desktop doesn't have TB3. antikk may be interested though.

Cheers - thanks for testing it. Very interesting.
