Not yet Frank, I've set the drives up as a software Raid 5 so any benchmarks would be a bit skewed anyway - what tool do you use for benchmarking ?

FrankM Posted April 19, 2019 Share Posted April 19, 2019 You can do this sudo dd if=/dev/zero of=sd.img bs=1M count=4096 conv=fdatasync and sudo iozone -e -I -a -s 100M -r 4k -r 16k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2 Thanks Link to comment Share on other sites More sharing options...
