Just noticed the 32GB 600x card from Transcend has dropped in price since i last checked. I got mine for $197 on eBay just a few months ago in July. That was the best price at the time. Today i just happened to see it going at multiple places, including Amazon, for under $160!
This is the card to get if you have a DSLR that shoots HD video. It’ll also let you blast continuous still frames as fast as your camera will go until the buffer is full. Slower cards will drop out on HD video recording and can’t keep up with high-speed continuous frames. “Brand name” cards (from Lexar and Sandisk) cost twice as much!
I’ve been using Transcend cards since i got my SD790 PowerShot in 2008 (that was an 8GB class 6 SDHC). I got a 600x 8GB card when i got my 7D this April, and quickly realized 8GB wasn’t big enough when shooting 25MB-per-shot RAW stills and HD video. I haven’t used all that many brands or types of cards for comparison, but these have never given me any problems.
In short, the Transcend 32GB 600x are solid quality, and the biggest, fastest CF cards at a great price!
Writing is only half the battle.
Don’t forget, to maximize the speed of transfers from the card to your computer you need a fast card reader. USB is too slow! I found this chart a while back showing the speeds of various card/reader combinations. The thing that stood out to me is that the fastest USB reader will hit 36MB/s, however some can do no better than 20MB/s — either way, far less than the 90MB/s maximum of 600x cards. A FireWire 800 CF card reader will be 2x faster than a USB reader. And an ExpressCard reader will be about 3x faster than USB. So multiply that out whenever you’re dumping a 32GB card to your computer. It could be the difference between checking Facebook updates vs going out to get lunch while you wait.
I’ve been using ExpressCard readers from Sonnet in my MacBook Pro, and have been very happy with the speed and convenience. If you have a notebook with an ExpressCard slot, Sonnet’s Multimedia Card reader is a must-have for SD and other smaller formats. It sits flush in the case, and makes viewing and copying photos super easy, no extra cables or parts needed — a no-brainer if you have a MBP with ExpressCard. I leave this reader in my MBP all the time. For CF cards, i got Sonnet’s CompactFlash reader. Slightly less convenient because the larger cards stick out from the side, but the speed is great, and it’ll mount two cards at once. And with both there’s no dangling cables and nothing taking up a USB or FireWire port.
