In the 256gb size and i am getting 50mb a sec on stats in tinfoil so I'm wondering if i can get a faster card or i have reached my limit. There also the possibly that a new card load time will be so little difference its not to worry.

The switch can only utilize A1 speed, if you get A2 card its only advantage is when transferring files on computer.
