If there are some incompetently implemented SSD's out there which do a

in use any more by the OS when the SSD is doing a GC copy/compaction
of a partially written flash sector), all I can do is do a sigh, and
wish that T13 had defined a "comptently implemented SSD bit" --- not
that Indilinix would admit if it they were incompetent.  :-/


The Sandforce drives seem even slower for mke2fs than the Indilinx.
And both types are faster than the Intel units for desktop use.
At least they optimized for the important commands.  :)
