I purchased a 'Jarhit' branded NVMe USB 3.1 caddy, which uses a Realtek RTL9210 chip. When I use a Corsair MP510 drive in this caddy I get the following speed:
Sequential Read (Q= 32,T= 1) : 439.662 MB/s
If I plug it into a USB 3 port, I get around the same speed.
If I put a Crucial ct500p1ssd8 in the caddy instead, over USB 3.1 I get:
Sequential Read (Q= 32,T= 1) : 846.943 MB/s
So I'm getting roughly half the speed with the Corsair drive in the caddy compared to the Crucial. Yet if I plug the drives into the motherboard, the Corsair is roughly twice the speed of the Crucial (1737.735 MB/s for the Crucial vs 3259.889 MB/s for the Corsair).
So, the caddy does do USB 3.1 (or at least greater than USB 3) speed. And the Corsair drive easily does USB 3.1 speeds. But together they only do USB 3, anyone know what the issue might be?
