may be used as a block range. This typically wont work with
direct IO, as that normally requires sector alignment.
+bs_is_seq_rand If this option is set, fio will use the normal read,write
+ blocksize settings as sequential,random instead. Any random
+ read or write will use the WRITE blocksize settings, and any
+ sequential read or write will use the READ blocksize setting.

zero_buffers If this option is given, fio will init the IO buffers to
all zeroes. The default is to fill them with random data.
