I'm not saying SBCs are "unusable" for desktop use cases, I'm saying I/O is the likely explanation for desktop responsiveness issues they encounter on SBCs.
- dijit 6y agoNobody here is talking about boot times, I was talking about responsiveness.. it's easy to test your theory, you can boot USB on the new RPI, and USB3.0 has quite a high bandwidth, definitely comparable to SATA2, nearly SATA3
- DCKing 6y agoThere's a good reason that they're making it more possible to boot a Raspberry Pi from USB. It's more reliable storage and has better performance for many use cases :)
