What is maximum reading speed of the Seagate INTEL SSDPEKKF256G8L SSD?

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

sqlio -LS -kR -i1 -f1 -t1 -s60 -p0 ...

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

             Throughput   Throughput   Latency
Block Size      MBs/sec      IOs/sec        ms
----------   ----------   ----------   -------
      -b16       171.23     10958.91         0
      -b64       521.42      8342.98         0
     -b256       686.46      2745.86         0
    -b1024      1213.80      1213.80         0
    -b4096      1426.33       356.58         2
   -b16384      1439.46        89.96        10
   -b65536      1440.00        22.50        43
  -b262144      1459.28         5.70       174

As you can see, the maximum reading speed, 1459.28 MBs/sec is reached with a block size of "-b262144", or 256 MB. 1459.28 MBs/sec is much better regular hard disk. But is still half of the speed of 3210 MBs/s given in the specs by the manufacture.
