The best way to find out the maximum reading speed of your SanDisk Cruzer Micro 8GB 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        14.61       935.29         0
      -b64        25.43       406.93         2
     -b256        24.81        99.27         9
    -b1024        25.23        25.23         9
    -b4096        25.67         6.41       155
   -b16384        26.44         1.65       604
   -b65536        26.36         0.41      2426
  -b262144        25.76         0.10      9935
