Reproducing CrystalDiskMark tests with fio - fixes for https://unix.stackexchange.com/revisions/480191/9

# The following changes proved to be necessary to make it work on CentOS 7:
#  * removed disk info (model, size) - not very useful, might not work in many cases.
#  * using "bw" instead of "bw_bytes" to support fio version 3.1 (those availible through yum @base)
#  * escaping exclamation mark in sed command
#  * the ".fiomark.txt" is not auto-removed 

LOOPS=5 #How many times to run each test
SIZE=1024 #Size of each test, multiples of 32 recommended for Q32 tests to give the most accurate results.
WRITEZERO=0 #Set whether to write zeroes or randoms to testfile (random is the default for both fio and crystaldiskmark); dd benchmarks typically only write zeroes which is why there can be a speed difference.

QSIZE=$(($SIZE / 32)) #Size of Q32Seq tests
SIZE+=m
QSIZE+=m
