Here are some basic things for those new to digital photography to ponder.
1) Know the difference between Compact Flash and Secure Digital (CF and SD). Most DSLRs and digital point-and-shoots use CF. But some of the newer cameras, and even some DSLRs use SD cards.
2) All flash memory cards are not created equally.
If you shoot Nikon, buy Lexar cards if you can afford them. They are optimized for Nikon shooters. Conversely, if you shoot Canon, don’t waste the money on Lexar cards. They won’t show a speed boost in your camera.
Avoid the very largest cards. Even 16-Gig cards scare me. The bigger the card, the more likely it will have a file allocation error and crash. There’s also the eggs in one basket worry.
If you want REALLY fast cards, look for UDMA cards, but make sure your camera supports them.
Just about once a day I get an e-mail asking me what I use. Well here’s the answer.
I now use Hoodman UDMA cards. In my tests they are consistently as fast as anything else and the company claims the cards have never been reported failing while in the field.
And here’s a tip on how to buy memory cards at the best prices. Go to www.dealram.com and compare.
