PSA: Veracrypt recommends against using hidden volumes on USB flash drives (source)

veracrypt.ioVeraCrypt - Free Open source disk encryption with strong security for the ParanoidVeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files.

Replying to an earlier post

A VeraCrypt volume resides on a device/filesystem that utilizes a wear-leveling mechanism (e.g. a flash-memory SSD or USB flash drive). A copy of (a fragment of) the VeraCrypt volume may remain on the device. Therefore, do not store hidden volumes on such devices/filesystems.

I understand that page is a bit dense, so I’m quoting the relevant text from the above source.
