Let's say you used a simple RandomAccessFile.  How could you implement
a busy lock field in the file to indicate the file was busy being
updated? or busy being read?  In RAM you have test and set locks to
check a value and set the value in one atomic operation.  How could
you simulate that without test and set hardware on the SSD? You can't
very well share a RAM lock between separate jobs.
