Mostly right: but many sticks have firmware and hardware performance limitations when they arenât used with FAT32: https://lwn.net/Articles/428584/ says In contrast, the more common SD cards and USB flash drives are very sensitive to specific access patterns and can show very high latencies for writes unless they are used with the preformatted FAT32 file layout. and Ideally, the drive expects all data to be written in full segments, which is what happens when recording a live video or storing a music collection on a FAT32 filesystem. and Additionally, only one segment can be open at a time; alternating between two segments will cause garbage collection at every access, slowing write speeds to a mere 33KB/s. That said, the FAT file table area (from 4MB to 8MB) is managed differently, enabling small writes to be done efficiently there. Hope this helps, James. -- E-mail: james@ | I don't believe there's a limit to the number of messages aprilcottage.co.uk | in my Orange mailbox.
