You can see:
… for a way to collect a lot of data for a long time duration; I suggest minimizing the amount of analog channel data captured to reduce disk usage and USB overhead – enable as few analog channels as possible and use as low of an analog sample frequency as you can tolerate.
Note: you can also ‘hack’ the calibration to improve the bandwidth at lower sample rates, see:

… for a script that reduces filtering (increases analog bandwidth). You may want to back it up first so you can go back to factory default. You will need to tweak it for which analog channels to edit, and it assumes only a Pro 16 device.
