There are many factors to consider when buying memory cards. Sure I want a fast card, but I also want a reliable card. For me, the Hoodman UDMA cards fit both requirements.
Their 4GB CF RAW cards are down to $99.99; the 8GB CF RAW are $179.99, and 16GB CF RAW cards are $299.99.
They’re NOT TWIP sponsors (although I wish they were), and I selected their products as a result of testing most of the popular brands.
45 MB per second. Built in the USA. Lifetime Warranty. Lead Free. What else do you need?
NOTE: Not all cameras take advantage of UDMA technology. Make sure your camera does before investing in UDMA memory.
UPDATE: I should note I am simply providing an answer here to a question I often receive by e-mail. I am not advocating anyone else use these cards. Use whatever works best for you.
