The Brother ADS-3100 is the starting point for a fixed AC-powered desk with an accessible rear USB port and a supported drive, though you need a compatible computer whenever scan options change. ADS-1300 suits smaller jobs that move around, provided power and setup access are verified. For recurring 61-to-100-sheet supported packets, or for changing scan options on the touchscreen, choose ADS-4900W.

Pick a scanner that really saves to USB storage, then fit its feeder and power supply to the size of your packets.
By the numbers
What we found across the document scanners we compare, plus the checked facts behind each finding.
A supported plain-paper packet of 90 sheets takes five initial feeder loads on the ADS-1300, two on the ADS-3100 and one on the ADS-4900W.
How we calculatedThe count covers initial feeder loads for supported 80 gsm Letter/A4 paper. Elapsed time, reliability and OCR accuracy are not estimated, and only these three models are included.

Decision guide
Begin by verifying USB storage support. After that, pick based on your usual packet size and the power source you have at the scanner.
Plugging a USB cable into a computer is different from having a USB storage destination. ES-400 II does not establish direct drive saving. ADS-3100 and ADS-1300 can save from their buttons, though changing scan options takes Remote Setup on a compatible computer. On ADS-4900W you can change USB scan options at its touchscreen. When different people bring different jobs, that can matter more than feeder size.
No AC adapter comes with the ADS-1300. Its documented power route requires a compatible USB-C supply of 15 W or higher, and Brother calls for the optional AC adapter when you use USB-A or a computer port that cannot supply enough. Budget for a supported supply before you plan a computer-free desk.
A 90-sheet packet of supported 80 gsm Letter/A4 paper takes five initial loads on ADS-1300, two on ADS-3100 and one on ADS-4900W. For a recurring pile, that gap matters. A 15-sheet job fits one load on all three, so choose by power, placement and how often settings need changing instead.
USB Mass Storage drives up to 128 GB formatted FAT12, FAT16, FAT32 or exFAT are documented for all three. Having a USB socket does not verify a drive that uses an unlisted format. Do not pull the drive out while scanning. Before putting the originals away, check the saved file for page count, orientation and legibility. Saving directly does not by itself give you searchable text or a backup.
3 options
Brother, ADS-3100
A scanner with 60-sheet capacity that hands scans to a drive, for an AC-powered desk with rear-port access. A compatible computer handles scan-option changes.
Top pick ifDirect drive saving for supported stacks of up to 60 sheets is what you need, along with AC power, rear-port access, a supported USB drive and a compatible computer for whenever scan options need changing.
Keep the rear drive port reachable, and have a compatible computer on hand for scan-option changes. A packet of more than 60 supported sheets takes another feeder load.
Brother, ADS-1300
A smaller scanner for short stacks, saving to a USB drive, whose power supply must be checked separately.
Pick this instead ifYour supported stacks stay within 20 sheets, a smaller unit matters, and a verified 15 W USB-C supply or the correct optional adapter, plus a supported drive and setup computer, are on hand.
It ships without a power supply. Use verified 15 W USB-C power or the correct optional adapter, and turn to computer Remote Setup when scan options need changing.
Brother, ADS-4900W
A scanner with 100-sheet capacity that hands off to a drive and changes options on its touchscreen, for a powered desk with room for its trays and rear drive port.
Pick this instead ifThe larger setup is justified by supported 61-to-100-sheet packets or touchscreen scan-option changes, as long as AC power, rear-port access and a supported USB drive are in place.
For a packet that already fits the 60-sheet ADS-3100, the 100-sheet feeder brings no initial-load advantage.
