While waiting for the GameShell to arrive I bought a new 32 GB Micro SD Card that qualifies for the new Application Performance Class (A1). This is especially geared toward installing apps in Android phones that are supposed to be as fast when installed to the SD card as when they are installed to the internal flash. There is also class A2, which is even faster, but only in sizes of 64 GB and more which is overkill for my GameShell.
While absolute read speeds don’t matter because the Gameshell’s internal SD reader is already maxed out, better random access performance has the potential for a big impact on booting Linux with many little tiny files. Or does it?
Here’s my readings, both with Image 0.21, extended via Gparted to full size. Stopped time from turning on up to display of launcher icons.
SanDisk Ultra 16 GB Class 10 HC I SanDisk Extreme 32 GB U3 A1
33,7 seconds 29,7 seconds
35,4 seconds 29,0 seconds
30,1 seconds 31,0 seconds
As you can see, it’s a bit inconclusive because of the one time the slower card booted in 30,1 seconds. What the heck? All in all, the faster card seems to shave of 3 to 5 seconds of boot time.
