Memory Card Speed Advantage?

Will the k100d, or the k100d super take advantage of a faster memory card? I thought I saw a posting somewhere that said it didn't matter. There are a lot of sales on medium speed chips, but I would hold out for a faster chip if it made a difference, particularly in the time it takes to upload to the computer.

Recently with my K10D, I was shooting in continuous mode with a Lexar 4GB SDHC Platinum II 60x. No problem. When I filled that, I changed to a Lexar 1GB (unknown speed, but think it is 20x maybe?). Noticed a big slowdown in writing to the card.

Originally, I thought it only made a difference when copying to and from the computer, but it does make a difference in write speed from the camera.

From what I've seen, the K10D can write at the approximate equivalent of 66. So, you'll see an improvement going up to that speed but not much of a win beyond it.

The K100D is somewhat slower innately, but you'll still definitely notice the effect of using a really slow card.

I'd looked into this before, and found the K100D to have a decent cache, good enough to take 3 RAW pictures in quick succession, but then it takes about 5 sec. to offload one of those pictures (10Mb), regardless of my memory card speed.

I have Toshiba 4Mb/sec and 6Mb/sec cards, with similar results - max write speed of about 2Mb/sec, limited by the K100D, not the memory card. So unless your memory card's write speed is slower than 2Mb/sec, it doesn't matter which one you choose in the K100D.

however, having a faster card can make a difference getting images onto your computer. Much less time.

I use a 2GB regular Sandisk card and a 1GB Extreme III card on my K100 and I have noticed ZERO difference in speed between the two. I haven't noticed a lot of difference loading onto the computer, but I really haven't paid much attention to that. If you have a K100, save your money and buy a larger capacity "regular" SD card.
