The same thing could be done by partitioning the SSD in the operating

fio job against the partition.
Basically, fio options offset/size should yield the same net result,
but I'm always unsure on what is the actual effect of mixing size and
time_based in a single job, and whether fio will wrap around the
specified size to the specified offset if the job is time-based. HOWTO
could have used some clarification on size/time_based interaction.
The HOWTO currently states:
time_based If set, fio will run for the duration of the runtime
specified even if the file(s) are completely read
or written. It will simply loop over the same workload
as many times as the runtime allows.
Especially the last sentence should make it clear, that it will simply
run the specified workload over and over until the time has passed. I'd
welcome changes to make that clearer, if it doesn't get the point across.
