Larger partition sizes on FAT32 with 4 KB cluster size could mean slow disk access, but I guess it would be OK to use FAT32 with 4 KB cluster size for 16 GB or 32 GB USB sticks, or hard-drive partitions should I order an old clearance-priced refurbished SATA hard drive. I'm reluctant to do heavy compiling on a USB stick; or FreeBSD or Linux with Wine for ReactOS or DOSBox for FreeDOS. Then I could use BSD or Linux filesystem. I've never actually run ReactOS. Closest I came was burning installation CD for 0.3.15 and finding it wouldn't boot.
