 The `fio` options used are: 
 
 `ioengine`: How the IO requests are issued to the kernel. 
 * `libaio`: Supports async IO for both direct and buffered IO. 
 * `mmap`: File is memory mapped with mmap(2) and data copied to/from using memcpy(3). 
+
 `rw type`: Type of I/O pattern. 
 * `randread`: Random reads. 
 * `randrw`: Random mixed reads and writes. 
 * `randwrite`: Random writes. 
 * `read`: Sequential reads. 
-* `write`: Sequential writes. Additional notes: Some jobs contain a `multi` prefix. This means that the same job runs more than once at the same time using its own file.
+* `write`: Sequential writes.

 ### Static `fio` values:
+
 Some `fio` values are not modified over all the jobs. 
-`runtime`: Tell `fio` to terminate processing after the specified period of time(seconds). 
-`loops`: Run the specified number of iterations of this job. Used to repeat the same workload a given number of times. 
-`iodepth`: Number of I/O units to keep in flight against the file. Note that increasing `iodepth` beyond 1 will not affect synchronous `ioengine`. 
-`size`: The total size of file I/O for each thread of this job. 
-`direct`: If value is true, use non-buffered I/O. This is usually O_`DIRECT`. 
-`blocksize`: The block size in bytes used for I/O units
