Just got a new Casio Exilim EX-Z750 digital camera. It’s really nice, but I don’t have time to play with it yet. So far, while just poking around it on a tour, it has succeeded in making me feel both fortunate and stupid. As I log more time with it, I’m sure that the balance will shift quickly toward fortunate. It really has a nice layout. OK, on to the main topic – a few questions about SD memory cards.
My main concern is card read and write speed. Simply, I don’t want the card to be a speed bottleneck for the camera. The camera should be the slowest component, to my way of thinking.
The term “high speed” doesn’t seem to indicate anything specific. When I purchased the camera, they gave me one 512MB card free. Not bad so far. Brand is “My Flash” from A-Data (Taiwan). The card has a few speed indications on it that I need some help interpreting.
The package says “60X”. It also says “9MB/sec read & 7MB/sec write.” It goes on to say that those speed ratings are based on a 128MB card.
What is considered “high speed” for an SD card these days?
Is the card I have (60X, etc) fast enough for my specific camera? Although it is a 7MP camera, I probably won’t use it above 4MP often.
Do I need to be careful what brand of SD card that I buy? In other words, can any of the lesser-known brands damage the camera?
If I buy another 512MB SD card, what type and speed would you recommend?
