If you can disable the write ATA write cache, then you have safety.
Unfortunately many cards under Linux show up as SCSI devices, and you
can't access this setting. Does anyone know if the newer SATA cards let
you control this?

You might want to keep and eye on the upcoming native windows port in
7.5 - It will come with a fearsome array of caveats... but you have been
running cygwin in production! - and I am inclined to think the native
port will be more solid than this configuration.
