Which scanner can save a stack straight to a USB drive?
Our pick
ADS-3100
Brother ADS-3100
Start with the Brother ADS-3100 for a fixed AC-powered desk, accessible rear USB port and supported drive. A compatible computer is needed when scan options change. ADS-1300 suits smaller movable jobs with verified power and setup access. Choose ADS-4900W for recurring 61-to-100-sheet supported packets or scan options changed on the touchscreen.
You need direct drive saving for supported stacks up to 60 sheets, with AC power, rear-port access, a supported USB drive and a compatible computer available when scan options need changing.
Automatic feeding and duplex scanning
Main trade-off
You need access to the rear drive port and a compatible computer for scan-option changes. Packets over 60 supported sheets need another feeder load.
Choose Brother ADS-1300 instead when
Supported stacks fit 20 sheets, a smaller unit matters, and a verified 15 W USB-C supply or correct optional adapter, supported drive and setup computer are available.
Power available without relying on an absent computer
Packet size within the feeder allowance
Choose a scanner with a real USB storage destination, then match its feeder and power supply to the packet size.

Brother ADS-3100
You need direct drive saving for supported stacks up to 60 sheets, with AC power, rear-port access, a supported USB drive and a compatible computer available when scan options need changing.
Rear USB memory-stick host accepts supported drives up to 128 GB
60-sheet ADF at the documented 20 lb paper basis
Single-pass duplex scanning and AC adapter included
Supported stacks fit 20 sheets, a smaller unit matters, and a verified 15 W USB-C supply or correct optional adapter, supported drive and setup computer are available.
USB memory-stick destination
20-sheet single-pass duplex ADF
Direct USB-C source must supply at least 15 W, with separate adapter rules for USB-A
Supported 61-to-100-sheet packets or touchscreen scan-option changes justify the larger setup, with AC power, rear-port access and a supported USB drive.
Dedicated rear USB memory-stick host
100-sheet ADF at the documented 20 lb basis
Single-pass duplex scanning, touchscreen and AC adapter included
USB scan options can be changed from the touchscreen
First verify USB storage support. Then choose around the normal packet size and the power source available at the scanner.
01
USB is not one capability
A USB computer cable is not a USB storage destination. ES-400 II does not establish direct drive saving. ADS-3100 and ADS-1300 can save from their buttons, but scan-option changes use Remote Setup on a compatible computer. ADS-4900W lets you change USB scan options on its touchscreen. That can matter more than feeder size when different people bring different jobs.
02
The small unit still needs electricity
ADS-1300 does not include an AC adapter. A 15 W or higher compatible USB-C supply is required for its documented power route, and Brother calls for the optional AC adapter when using USB-A or an insufficient computer port. Budget a supported supply before planning a computer-free desk.
03
Choose a feeder for the actual packet
A 90-sheet packet of supported 80 gsm Letter/A4 paper needs five initial loads on ADS-1300, two on ADS-3100 and one on ADS-4900W. That difference matters for a recurring pile. For a 15-sheet job all three fit one load, so choose by power, placement and how often settings need changing instead.
04
Saving a file is only the first part of archiving
All three document USB Mass Storage drives up to 128 GB formatted FAT12, FAT16, FAT32 or exFAT. A drive using an unlisted format is not verified by the USB socket alone. Do not remove it during scanning. Check the saved file for page count, orientation and legibility before putting originals away. Direct saving does not by itself establish searchable text or a backup.
Check these before buying
Use a supported USB Mass Storage drive up to 128 GB in FAT12, FAT16, FAT32 or exFAT. Confirm the needed output format separately.
Leave room for open trays and access to the drive port. ADS-3100 and ADS-4900W use a rear USB host.
Keep a compatible setup computer available for ADS-1300 or ADS-3100 scan-option changes. ADS-4900W provides touchscreen options.
For ADS-1300, include verified 15 W USB-C power or the correct optional adapter. For all three, prepare supported originals and remove staples.
What this comparison cannot tell you
This shortlist uses source-verified finalists, not a claim that every catalog scanner has been fully tested for every USB drive.
Routine USB saving and changing its settings are separate jobs. ADS-1300 and ADS-3100 use computer-based Remote Setup for option changes.
No speed, OCR-accuracy or paper-feed reliability testing is claimed.
