The hard disks are of type SAS and attached to the adaptec raid controller as single disks. One Intel SSD as OS-Filesystem. The other one is attached PCIe SSD-m.2 Adapter. An additional m.2 SSD will be attached for later tests with ssd caching.
For the tests I will make use of fio - flexible I/O tester - one of the currently most popular storage benchmarking tools.
My production scenario will be webhosting. So it will be 25% write and 75% read. I will test that probably later after the basic read/write tests.
At first I'm making sure the device names I use are fixed so my tests will not overwrite any of the wrong disks. This may happen under linux because there is no fixed device naming of storage devices. The ordering may be different at every reboot. And it actually is, as I have noticed.
So I'm checking the serial numbers and copy the device file names to unique names I will be using then.
What's regarding partitions: I try to avoid using them and use whole disks instead as it makes the procedere simpler.

I need a little clarification in understanding why there would be a need for a benchmark file when used with a backup script. Logically thinking would tell me that the backups itself(backuptest.tgz) would have the time created and etc. So what would be the purpose of such a file:
