While full-size SDHC cards enjoy both large capacity of up to 32GB (even larger with SDXC) and high speed Class 10 performance, mobile oriented microSDHC cards aren’t quite there yet. On the mobile front, the industry has yet to produce a card that’s 32GB (or larger) with high-speed Class 10 or Class 6 cards. Until than we’re left with the choice of choosing either speed (Class 6 or higher) or high capacity. Today’s review does just that: We’ll compare the highest capacity card available ( the Sandisk 32GB Class 2) against the fastest high capacity card available on the market (the Lexar 16GB Class 6). Based on your needs, do you need speed or capacity?
A matter of speed
The SD association defines four levels of Speed Class: 2, 4, 6 and with 10 added just recently. Interestingly these Class levels reveal a card’s minimum sustained transfer and not the usual maximum speed: Speed Class 2 guarantees a minimum transfer speed of 2 mega bytes per second (MB/s), Speed Class 4, 6 and 10 guarantee a minimum transfer speed of 4 , 6 and 10MB/s respectively. Some manufacturer of full-size cards are now even claiming to have a minimum transfer speeds of 16 MB/s or Class 16. When it comes to microSD card, it’s safe to say that they are a bit slower. Do keep in mind that the maximum read/write speed can be much higher but not necessarily maintained continuously. In other words a card can reach 30MB/s, but can maintain that speed for only 5 seconds for example.
