I’ve never really been one to check the read and write speeds on memory cards. I realise there’s a difference between the generic cards and the ‘extreme’ high-speed versions, but I always thought that even the basic cards would be ‘good enough’ for shooting photos and the occasional video.
Of course, I realised the error of my ways once I started shooting higher-megapixel photos and high definition video. I took my Canon PowerShot SX30 IS to Big Day Out last month, and while the 35x zoom worked fantastically for capturing the artists on stage, the generic SanDisk SDHC card I was using could only record just over a minute of 720p footage each time. This was despite the specs saying that it could record 20 minutes and 43 seconds at 720p resolution.
I went to a media briefing this morning for SanDisk’s new 32GB Extreme Pro SDHC UHS-1 card, which offers the fastest ever read and write speeds of up to 45MB/s. Using that in my Canon PowerShot SX30 IS, I was able to record 720p video for even longer than the advertised time, at just over 25 minutes. Much better! This card is best suited for cameras that have a fast burst mode/continuous shooting feature, like my Sony NEX-5, which is capable of shooting 7 frames per second at the full 14.2 megapixels, or any camera that supports high definition video recording.
Of course, you’ll have to pay extra for the privilege of additional speed. Compared to the generic 32GB card, which has a street price of around $80, the new 32GB SanDisk Extreme Pro SDHC UHS-1 card retails for a cool $254.95. There are SanDisk cards in between those two, however, if you don’t want to spend that much, such as the Ultra range with a speed of 15MB/s and the Extreme range at 30MB/s. I also got a press release for SanDisk’s new 128GB Extreme Pro CompactFlash card, which offers an insane 100MB/s – and an equally insane pricetag of $1529. Yowsers!
