Reference update and Linux reimplementation of Dennis Publishing disk I/O performance tests

Note that this repo exists to track code changes and does not include the sample file sets. A full version of the desk test kit, including the media and data files required for testing, may be found at https://www.theos-cloud.eu/index.php/s/6YapNo5a6yKkw4y

To create a 1GB file for use in the large file transfer test: fallocate -l 1G large.img

OG testing procotol:

• Format review disk ext4
• Create mount points: sudo mkdir {/mnt/ramdisk/, r /mnt/testdisk/}
• Set mount point permissions: sudo chmod 777 /mnt/ramdisk/ /mnt/testdisk/
• Mount review disk at /mnt/testdisk - for example: sudo mount /dev/nvme0n1 /mnt/testdisk
• Create and mount a 4GB ramdisk: sudo mount -t tmpfs -o size=4g tmpfs /mnt/ramdisk
• Copy all disktests to the ramdisk's root
• cd to the ramdisk: cd /mnt/ramdisk
• Run the test file ./storagetest
• Copy the times from results.txt into the Test Results sheet of hard_disk_test_results.ods to calculate read/write speeds in MB/s

• Aio-stress
• Postmark
• Dbench 12 clients

Testing SSD performance while full

After dumping your results, entirely fill the test disk with data. Reformat -- NOT a low level format -- and re-run tests.
