Disk Storage Measurements

Introduction

We collect fio results from various disks on this page. We run fio as follows:

export disk=SERVER-DISKMODEL
export dev=/dev/sdXX
( for YYY in $(seq 1 16); do fio --filename=$dev --direct=1 --fsync=1 --rw=write --bs=4k --numjobs=$YYY --iodepth=1 --runtime=60 --time_based --group_reporting --name=$disk-4k-sync-write-$YYY; done) | tee ${disk}.txt
