It depends on your dataset, I use 32 GiB personally, back in the day I used
to use 2048 MiB but with drive backup speeds > 100 MiB/s the drive barely spins
up for a few seconds before it has to take a moment and write a marker every
2 gigabytes, I recommend a higher value.

Obviously the higher the value means the longer it will take to seek for an
individual file so its up to you to pick a good value.
