Flash storage like USB sticks is a crude comparison to an SSD or NVMe with cache and a controller capable of parallel operations.
A USB flash drive is like a dumpster. Big bandwidth when the lid is open but itβs got poor performance for fetching and storing lots of things all the time.
An SSD or NVMe is more like a rolling auto tool chest. Same big metal box, but much more performant for complex and numerous read and write loads.
Or to use a computer analogy: SSD is like a hard disk, USB flash is like a tape drive.
