Kinoma Notes

Remov­able mem­ory is pretty much all alike, isn’t it?

We wish! For bet­ter or worse, there can be big dif­fer­ences in qual­ity and speed between one stor­age card and another.

For qual­ity, all you can really do is buy a brand you trust. But for speed, the good news is that there’s now a stan­dard way of clas­si­fy­ing the through­put of SD and SDHC cards — the Speed Class.

It’s really easy to under­stand, too. Class 2 cards guar­an­tee a min­i­mum trans­fer speed of 2 MB/second, Class 4 cards a min­i­mum speed of 4 MB/second, etc. A card’s Speed Class should be clearly marked as a num­ber in a round “C”, as shown above.

We rec­om­mend that you always buy stor­age cards that are Class 4 or higher, and we nor­mally buy Class 6 cards ourselves.

With a faster card your phone spends less time on data trans­fers, which trans­lates to more effi­cient media play­back. As an added bonus, copy­ing media between the card and a PC will be faster as well.
