The CPU is a 900Mhz Celeron. I think you may be right about the speed of the SSD. From initial power up to when the login prompt appears is almost a minute. I have a 8G class 6 SD flash. would I be better off with the OS on it than the SSD?
Well the 8gb would give you more headroom. Speed about the same, just medium.
They never should have sold those without a 20gb SSD so we have to juggle a flash
drive or portable hard drive if we upgrade and need more headroom then. Experiment
with the 8gb flash, it's fine here for LXDE and a browser. Use the 4gb for documents, etc..
Or use the 4gb for system backup at high compression just to be safe.
