Are there some? I don't know one. I used a 512MB Compact FLash card
with FFS for my HP Jornada and a 256MB USB flash drive (with FFS and CGD) t=

carry data around. Never had any Problems.

IMO hardware shouldn't make a difference.

What's your requirement? Do you want to substitute a hard drive? Or
carry around data?

nodev, nocoredump, noatime, soft dependencies is what I use for my USB
flash drive.

FAT16/FAT32 is usually used.
