SanDisk has announced its latest range of flash memory products to cater for photographers and videographers using SDHC or CompactFlash.
The SDHC card, dubbed Extreme Pro SDHC UHS-1, is the first from the company to use the new Ultra High Speed (UHS) specification from the SD Association. This card can achieve 45MB per second read/write speed, which is useful for photographers working with high-resolution RAW and JPEG images in high-end cameras that take SDHC. These speeds are also applied when transferring data from the SDHC card to a computer for post-production or archival purposes (pending a fast enough card reader). In terms of video capabilities, the UHS-1 specification means that the card must meet a minimum sustained read/write speed of 10MB per second.
The bad news? For now at least, the only camera that is compatible with the UHS specification is the Nikon D7000. Other camera users can of course use these cards as they are backwards-compatible, but they may not see the same performance results. In practical situations, SanDisk provided a live demonstration to prove how fast the new card was, pitting it against a previous SDHC Ultra card from the range. Firing off 10 shots in continuous mode (RAW+JPEG), the Ultra card took 27 seconds to process its burst on the D7000, while the Extreme Pro card took 10 seconds.
The cards are also weather-proof: able to withstand temperatures from -25 to 85 degrees Celsius, waterproof for 72 hours, and shockproof from 5 metres.
In the CompactFlash field, SanDisk has released the world's fastest card with up to 100MB per second read/write speeds in 128GB capacity.
The Extreme Pro SDHC cards come in capacities ranging from 8GB to 32GB and are priced from AU$66.55 to AU$254.95 depending on capacity. The Extreme Pro CompactFlash card is available for AU$1529 for 128GB.
