Therefore you have a Class 4 or better SD card.

For your interest, Q3A60 contains a new storage LED flashing feature
during fs-update.  It can be useful for visually comparing the
performance of different SD cards.

Technical details: "OLPC XO-1.5 - strobe HDD_LED# during fs-update. The
LED is toggled once for each zblock: line in the input file. This shows
the processing speed, and is affected initially by complexity of
decompression, and eventually by SD card write rate. Faster and slower
SD cards are more easily compared. Cost of 1.7 microseconds per LED
toggle, but as writes to SD are asynchronous the run time is unchanged."
