Test results of three USB flash memories attached to the Raspberry Pi USB 3.0 port and they work as boot drives.
Update v1 added HP USB 3.0 32GB, the new lowest benchmark devide I have tested.
The HP Flash USB 3.0 32GB benchmark, 575, is almost 1/3 the benchmark of the
Lexar micoSDHC-I at 1448.
Raspberry Pi Model 4 B 4 GB
Run the benchmark on your Raspberry Pi with the CLI command:
sudo curl https://raw.githubusercontent.com/TheRemote/PiBenchmarks/master/Storage.sh | sudo bash
The website's very high benchmark scores (9,000 to 10,000) are sometimes from CPUs that are overclock to 2GHz and 2.1GHz.
The normal RPi 4 CPU clock speed is 1.5 GHz.
