James hat sich in seinem Blog ausführlich mit dem Thema IO Benchmarking auseinander gesetzt. Herausgekommen sind hierbei diverse Übersichten und Infos zu funktionierender/ nicht funktionierender Hardware als auch ein fertiges Benchmarking Script, welches automatisiert IO Tests durchführt und einen Score berechnet. Die gesamte Benchmarking Liste der von usern getesteten Hardware findet sich unter https://storage.jamesachambers.com/ , dort finden sich auch die Scores.

Benchmarking Script:

sudo curl https://raw.githubusercontent.com/TheRemote/PiBenchmarks/master/Storage.sh | sudo bash

Beispiel:

Hardware: Pi Model 3 B+ und einem SanDisk Cruzer 16GB USB-Stick USB2

Score (s.u.): 471 (* laut User Liste schnellster Test bisher ca. 11.000 mit einer USB3 SSD)
