Not in an absolute sense, but the speed limitations of USB 2.0 do become immediately apparent when you try to run an operating system off of it. Even a super lightweight Linux is usually going to load binaries from disk when executed, and logs are going to be written to disk, etc.
Also page faults are going to be slooooow.

Raspberry Pi forced an entire generation of software hacks to deal with slow os/boot disk speeds (esp. the earlier models but also just the affordability aspect even with the new models).
- LoganDark 3y agoFor small OS images you can sometimes get away with loading the whole thing into RAM on boot and then running from RAM, which essentially removes the boot drive from the equation completely except for that initial copy to RAM. I always pick this option when I use Clonezilla because usually I'm booting it from a USB stick and everything would be slow the whole time if I didn't put it into RAM.
- justsomehnguy 3y agoUgh, not the speed itself (you can have up to 30MB/s, which is more than enough), but the ability to serve multiple requests simultaneously, ie Queue Depth. Most of the time you xan assume QD for them is 2 and you would't miss at all.
