dd, or cat with a shell redirect are all you need to write that iso.
My trouble with dd is all the flags I need to remember to make it fast and more convenient. ddif=file of=/dev/device oflag=direct status=progress bs=1M is there anything I’m missing?
Prevents the writes from piling up in the cache. dd will report the transfer is done when the writes have been cached so this setting prevents dd from exiting until the data has been written completely to the block device.
This ensures the cache is written before dd exits, but doesn’t necessarily write to disk directly. This means that, for small files, dd can finish release its hold on the input file quicker
