USB 2.0 Capacity Limitations?

Just wondering if USB 2.0 flash drives have a storage capacity limitation size.

I don’t believe there are any limitations. Though the theoretical speed over USB 2.0 is 60MBps, I wouldn’t want a really large drive to be that slow.

The only limitation would be the file format you use. If you use FAT32 for some reason, that would have a maximum file size of 4GB.

Older storage technology had a capacity limitation of 2 TB. This is not really specific to USB 2.0, but you could encounter it with a USB 2.0 hard drive enclosure.

USB 2 spec defines transfer speeds, not storage capacity.

The capacity of the flash drives will range based on whether its MBR vs GPT, and the filesystem in use, FAT32, ExFAT, EXT4, etc.


The limitation of a drive is based on the file systemand physics really, regardless wether it is a thumb drive, usb harddrive, or an internal sata drive etc.
Obvious at like 100 trillion billion tebi bytes, some hardware limitations may occurs in the firmware of the platform.
But at todays standards there no real roof since were talking 128+ max partitions, at Tebi+ bytes size, pr. partition, using most modern filesystems, and gpt.
