What Others Think

This gives misleading results because the MB/s reported is printed by `dd` before the last sync and before the outer `time`. This discrepancy has a big influence on the results.

The dd command reads one block of data, processes it, and outputs it to a file. For both the input and output files, you may define the block size. To aid your budget, you can always keep the price of your custom paper low, so go to https://sopwritingservices.net/ and try. The argument "bs" provides the block size for both the input and output files in the dd command example above.
