[Amazon.ca] A ADWITS NVMe M.2 PCIe SSD Enclosure - all-time low price PLUS $3 off coupon

Good reviews on this M.2 form factor SSD enclosure. Includes USB C and A cables.

All time low price according to the three humped animal, $3 off coupon brings the price down from $51.99 to $31.99. I got free shipping and no tax in BC.

How much would this bottle neck the speed?

Real world speeds seem to be as low as 400MB/s so quite a lot.

What causes the bottleneck? Is it the USB port, enclosure driver, or other component?

Outside of a set of very specific circumstances, I've never understood NVMe externals.

So far the only use case people have come up with is dual booting on a device that you can't easily add another drive to.
In another thread, some user said fast backups citing speed, but I don't buy that especially given the cost over a hard drive.

But I get crapped on in any thread I mention this and no one so far has come up with a decent use case.

USB.
Even a 10gbps USB port (which you probably don't have) is "only" 800MB/s which is pretty slow for NVMe.
I can't argue that it's not fast, but to me it's still a waste of money.

Shouldn't USB 3.2 be 10 Gbps = 1250 Mbps?
Maybe no USB port on a computer can manage that?

USB2 should be 480mbps or 60MB/s.
It's more like 20MB/s.

Real world is often different than paper specs.
Wifi is like this too.

I really meant USB 3.2 :)

Just for argument sake.

The top real life performance would be about 800 MBps?

Good to know.

2.5" enclosure, different league portability-wise to M.2. A SATA M.2 enclosure (for a SATA M.2 of course) is a better comparison, and also cheap to boot.

I have this exact one and works well.

too many factors and how they handle the traffic. When it comes to USB, YMMV.

Is the coupon still available for anyone else? I can't seem to see it on the page.

Yep, coupon is gone.

A whole lot of inaccurate assumptions going on in this thread. I have this enclosure and an Adata SX8200. My sequential transfer rates are around 950 MBps to a USB 3.1 Gen 2 enabled MacBook Pro.

Overkill? Sure. I also realize I’m severely limiting my SSD’s performance by sticking it in an enclosure. But to get similar performance in an external drive you’d have to pay a *lot* more for something like a Samsung x5.

Good for cloning your boot drive to a NVMe drive and then swapping it in, or if you yank out a NVMe drive to replace it with a larger capacity unit and want to use the old one as an external.
