Advanced users • Re: Testing class A2 SD cards with Command Queueing on Pi 5

I just tested my Kingston canvas Go Plus 128GB
This is the fastest SD card I've ever seen and tested in random write and read IOPS, and I've had several, even Sandisk, used it first on the Pi 3B+ and it's very fast on it, a few days ago I switched to the Pi 5 and with it it is even faster, below are the tests with and without Command Queueing.

Code:

mmc0: Command Queue Engine enabled, 31 tagsmmc0: new ultra high speed SDR104 SDXC card at address 5048mmcblk0: mmc0:5048 SD128 116 GiBmmcblk0: p1 p2mmcblk0: mmc0:5048 SD128 116 GiB

Without Command Queueing:

Code:
