A

The best way to find out the maximum writing speed of your Seagate INTEL SSDPEKKF256G8L SSD is to run writing tests with a single large block of different block sizes:

sqlio -LS -kR -i1 -f1 -t1 -s300 -p0 ...

If we run SQLIO with above options and different block sizes, we should be able to find the maximum writing speed:

             Throughput   Throughput   Latency
Block Size      MBs/sec      IOs/sec        ms
----------   ----------   ----------   -------
      -b16       300.65     19242.09         0
      -b64       630.65     10090.50         0
     -b256       818.27      3273.11         0
    -b1024       836.14       836.14         0
    -b4096       905.87       226.46         3
   -b16384       877.49        54.84        17
   -b65536       910.41        14.22        69
  -b262144       878.20         3.43       291

As you can see, the maximum writing speed, 910.41 MBs/sec is reached with a block size of "-b65536", or 64 MB. 910.41 MBs/sec is much better regular hard disk. But is still much less the speed of 1315 MBs/s given in the specs by the manufacture
