If you wish to record to a USB device then the minimum device is a PIC24 family device that has USB, as these are the minimum device with USB OTG, i.e. can be a USB master. PIC16 & PIC18 devices with USB are anly slave devices. However if you can use a suitably formatted EEPROM or FRAM with a PIC16 or PIC18 to store data then you could make it look like a USB drive when connected to a PC to download, if you don't specifically require removable media on the data capture device. But any use of USB will require using a Microchip library for the USB interface, but all the rest can be written in assembler if you wish. If you can use an SD card then you could use a PIC16 or PIC18 with SPI interface. You will need a reasonable amount of RAM to handle the file system buffering. Whichever way you do it you will probably want to use the Chan FatFS library for the file system handling.
