Digital cameras and camcorders today are always matching towards higher resolution and more detailed images and recordings. To be able to store enough of the video to make recording times last requires ever larger capacity memory cards. Kingston has offered up a new SDXC card at Computex that is speed Class 10.
The new SDXC format is ushering in memory cards that look like the SD cards we have had for years, but pack huge amounts of storage into the small space. The SDXC format can handle up to 2TB of storage capacity.
Digital SLR cameras generally save their images to one of two different types of memory card: the majority support CompactFlash (CF), while others such as Nikon's D3000 and the Canon Rebel XS write data onto Secure Digital (SD) memory cards. The latter are inexpensive and favorable for their smaller form factor and better physical contact surface instead of fragile pins. Some DSLRs, however, have dual card slots, such as the Canon Digital EOS 1D Mark II N or the Nikon D300s. Last time around, we reviewed number of UDMA-6 high performance CompactFlash cards on the world's fastest DSLR, the Canon EOS 1D Mark IV, and we promised to put some Class-10 SDHCs through the same tests. That day has come, so read on to find out how Class 10 SDHCs stack against UDMA-rated CF on the Mark IV.
Toshiba have announced a pair of new, Full HD camcorders, the Camileo SX500 and SX900, each recording in 1920 x 1080 30p/60i to SD/SDHC/SDXC memory cards up to 64GB in size. The barrel-format cameras - which can also grab 10- and 14-megapixel stills respectively - each have electronic image stabilization together with face and color tracking.
Panasonic have outed their latest Micro Four Thirds camera, but rather than try to squeeze DSLR-style interchangeable lens flexibility into your pocket, they're strapping it to the front of a relatively compact HD camcorder. The Panasonic AG-AF100 has a single-chip micro 4/3-inch 12.1-megapixel sensor and records at native 1080/24p.
Looking for a huge quantity of speedy flash memory for your DSLR or HD camcorder? SanDisk have pushed their 64GB Ultra SDXC memory card out the door, and the Class 4 card certainly promises enough. Up to 15MB/sec read speeds are supported, with data kept in exFAT file structure; one card is enough for over eight hours of HD video at 9Mbps quality.
One of the age-old dilemmas in the technology world is getting both sides of the new technology coin in play at once. When a new technology like SDXC is unveiled it looks great, but before the cards will be adopted by users and manufacturers there have to be readers and SDXC cards on the market at the same time.
