What is the block size for writing to a flash drive (the minimal size that gets erased and rewritten)? Does it depend on the block size the drive was formatted by, or is it independent of that?
Does the drive rewrite a block every time I hit "save" on a document, or does it remember the changes and write them when I click "eject drive"? Does it matter if it's NTFS or exFat?
My goal is to minimize drive wear. I can format the drive with any file system, and I can copy documents onto my computer before work and copy back after, but would rather not do that if it's not needed.
