	iterations: 1x
	nr_threads: 32t
	disk: 1HDD
	fs: f2fs
	filesize: 16MB
	test_size: 60G
	sync_method: NoSync
	nr_directories: 16d
	nr_files_per_directory: 256fpd
	cpufreq_governor: performance
	ucode: 0x500002b

test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
