I've been running a class 6 card (by PQI) in my B2 XO-1.5 for about two
weeks now. While there is an improvement in responsiveness, I would not
be willing to swear to an absence of "unexplained long delays".
Each time I install a new build, I apply the same customizations (using
data already stored on my external_slot "permanent" SD card (class 6)).
These involve installing some rpms, then doing some 'vi' and mainly
some 'cp'. At least twice during this customization process, some
individual command takes much longer than normal to complete. My own
guess as to the probable cause was 'garbage collection' by python.
IIRC, these "unexpected delays" have not vanished with the installation
of the class 6 microSD card.
Also (relevant to the topic of this thread), in Record on the XO-1.5
there is a noticeable delay between when I wave my hand "on camera", and
when that motion shows up on the screen. My impression was that in
switching the microSD card from class 2 to class 6 this "lag" got
shorter - but it is definitely still there.
