As far as I know, a thumb-drive or hdd that you connect to a cRIO USB port has to be formated using FAT. It would be very handy if NI would support attaching drives formated with the Reliance NITRO file-format. This could in some cases also lessen the pain of being stuck with Reliance (old version) on the cRIO main drive. It would also ensure deterministic file IO on the USB drives in case of power failure, un-expected device disconnection etc.
Thanks for reading and hope for your vote!
