How can the block size of a file store be portably obtained in Java 7?

问题

I've looked at java.nio.file.attribute.Attributes and java.nio.file.FileStore, but couldn't find a way to discover the block-size of a disk-file.

Here is an article on buffer size vs I/O throughput. Synopsis: nio handles all of that for you. This SO post concludes you should use a power of 2.
