Go.

I was interested in having a "higher-performing" XO-1.5 -- so the card I
bought back then was a class 6.  It is likely the micro-SD card you have
now is a class 2 -- so your new card (Sandisk has good reputation for
reliable SD cards) will perform the same as what you are used to.

Since your existing card is deteriorating - go ahead and replace it.
