Lexar Pro CF 8G = Lexar Professional Series 8 GB 300x UDMA CF memory card (CF8GB-300-381) SanDisk CF 8G = Sandisk 8GB Extreme UDMA 400x CF memory card (SDCFX-008G) LEGEND of GRAPHS ( RED bar means FASTEST ) The first graph gives you an idea of how fast you can transfer photos or video from the memory card to your MacBook Pro. I used QuickBench's "Large" test (2MB - 10MB test sizes) and various card readers to test the actual read/write speed of various SD and CF cards that are touted as fast performers to see if they meet or exceed the ratings and to see if they can be used for HD video on various digital cameras. Regardless of the rating, the actual speed can be slower (or faster) than the rating. The SanDisk Extreme CF card we tested had "60MB/s" on the label. Some manufacturers are now rating their cards in MB/s. So a 300X = up to 45MB/s and 400X = up to 60MB/s. The formula to figure out the transfer speed in MB/s is R = K * 150. In the case of Compact Flash (CF), a rating such as 300X or 400X is often used. The SanDisk Extreme SDHC card we tested had "30MB/s" on the label.
Some Secure Digital (SD) card makers are now rating their cards in terms of MB/s. I say you should go for class 10 (10MB/s or better) just to make sure.

The Nikon S8000 manual states, "Memory cards with an SD Speed Class rating of 6 or faster are recommended for recording movies." The "6" rating means at least 6MB/s. It also helps to have a fast memory card if you are doing continuous shooting. With compact digital cameras and pro-sumer digital SLRs doing HD video recording, your existing memory card(s) may not be fast enough. At the same time, we were looking at upgrading our memory cards. Unfortunately, no timescale has been given as to when that will be released and while some note that the issue is more likely to occur with older cards, the lack of predictability is a problem right now.We recently upgraded our camera equipment.

Some people who have contacted Apple have been told that the company knows of the problem and that a fix is coming via a software update. Worryingly, there doesn't appear a pattern to much of what people are reporting but there might be a sliver of light at the end of the tunnel. All my cards work as expected in my 3 other USB card readers. I tried reformatting them w/ the MBP and that didn't seem to make a difference. These are all Sandisk Ultra cards, both XC and HC, that were formatted in my camera. Half the time it'll recognize the card successfully (though it takes anywhere from 30s to 1m) and half the time it'll throw an error. Just seems to be super flakey and inconsistent. Some cards reportedly cause Finder to crash, while others are able to transfer data but at a speed much slower than expected. Apple's new 14 and 16-inch MacBook Pro brings SD cards back to the Mac, but it isn't all sunshine and rainbows - because not all SD cards appear to work properly and there's little explanation as to why.Īccording to a MacRumors report, multiple people have posted to a thread in its forums to report that some SD cards don't appear to work correctly when inserted into the MacBook Pro's slot.
