In reply to Vlad Bieg. They mostly cache mapping tables. Very little actual user data is cached.

In reply to Vlad Bieg. Let's say with this flash drive, a 5gb file can be "written" to it in 1 second. Then I want to safely eject. The operating system will either say the disk is in use, take a very long time to unmount, or some other undefined behavior. This will confuse the user. The operating system's built in caching is probably more effective than this.

In reply to Benjamin Hojnik. All external disks (mechanical and SSDs based, old and new designs) use caching. Yes, pulling out removable media before it completes the operation, without proper ejecting it, is (and always was) not advisable. Nothing conceptually new here, really.
