[gentoo-embedded] file system question

[David Relson]

G'day,

I'm porting the software for an embedded medical device from DOS to
Linux and am wondering which file systems are appropriate and which are
not.  The device's mass storage is a Disk-on-Module solid state flash
drive.  Data is presently written at approx 100 bytes every 30 seconds
but that might change to 100 bytes every second.  The device has a
watchdog (recently activated) and during today's session it was
triggered and wiped out my file system.

Anybody have recommendations on which file system to use and the
appropriate settings?

Anybody have suggested readings so I can educate myself?

Thank you.

David
