One nice feature of the Nikon D300s is the dual memory card slots for both SD and CompactFlash cards. Doubling your memory capacity from, say, 32GB to 64GB means you won’t be swapping cards any time this decade. That’s good news, but even better: you can program the D300s to capture photos to one card while instantaneously backing up to the other. Or send RAW files to the CF and JPEGs to the SD (or vice versa). On location, a pro can pass one card off to the client and fine-tune the other set of photos in-camera or on a laptop.
Going to Extremes
A few words on memory cards are in order.
First, this is one area where you don’t want to be caught penny-pinching. So don’t be tempted by a dirt-cheap, no-name brand (“Hey, Ma, 8GBs for only ten bucks!”). Remember, this is where your precious photos are stored and you don’t want to wind up empty-handed due to gotcha corruption. Cheap cards are prone to failure. I use only professional cards made by SanDisk, Lexar, and Kingston and I’ve never had a gotcha, glitch or failure.
Being a speed-freak, I’m partial to SanDisk’s Extreme Pro series. I’m using a 16GB CF and 16GB SDHC in the D300s. It’s not just the 32GB capacity I’m comfortable with, but the astounding speed and performance of the Extreme Pro—600x, 90 MB/s. Doesn’t get any better than that, outside of the track at the Indy 500. I rely on SanDisk when I’m shooting in full, 7 FPS Continuous Mode, or when capturing 1080 HD video. The cards never hold you back and, in fact, they always seem to be one step ahead.
Finally, there’s the durability factor. Extreme Pro cards are torture-tested to withstand a professional’s worst-case scenario, like shooting in a snow storm at -25, or maybe out in the desert trying to capture a mirage in high def. SanDisk cards are even sealed with water-resistant RTF silicone for bonus protection. They come with a limited lifetime warranty and free RescuePro recovery software which I’ve never had to try.
