I might of gone a little bit crazy 8) I bought a external enclosure w/ a JMS583 chip (image below) & installed a Samsung 970 EVO NVMe PCIe M.2 in it for USB speed testing on 2 Desktops & 1 Laptop PCs I have here @ home. Next I did a unscientific speed test watching the Windows 10 Read Speeds & taking a screenshot of the fastest. I also ran the AS SSD Benchmark app. on the external drive also (sorry couldn't fine one that will benchmark a external drive besides AS SSD). Below are my results, the external case I used & a comparison w/ a plain old Samsung 860 EVO SSD, the results in the comparison are surprising (image below), the best was the Thunderbolt 3 speeds. Spoiler *To much info?
For comparison this is a Silicon Power 128Gb SSD I got on Amazon for $30. I usually buy Samsung, but I didn't have much money when I bought it.
Your not reading the speed of the drive itself per se. But the limited usb speed (and chip) that the drive is connected too. Makes it silly to think an NVMe would work any better than a sata SSD using as an external
Yep, I found that out w/ my testing it as a external drive, was hoping for faster. At least I found something to plug into the Thunderbolt 3 port
