A

The best way to find out the maximum reading speed of your SanDisk Cruzer Blade 32GB Flash Drive 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         9.43       603.78         1
      -b64        15.94       255.19         3
     -b256        16.09        64.36        14
    -b1024        18.55        18.55        53
    -b4096        18.55         4.63       215
   -b16384        18.14         1.13       881
   -b65536        18.33         0.28      3489
  -b262144        18.40         0.07     13931

As you can see, the maximum reading speed, 18.55 MBs/sec is reached with a block size of "-b1024", or 1 MB.
