The brand of DSLR camera you purchase has a lot to do with the sort of storage format that the camera needs. The closer you get to a true professional DSLR the more likely you are to need pro storage rather than the more consumer focused SD cards. Silicon Power has unveiled a new larger capacity CF card for DSLR shooters that has lots of speed and storage space.
The card is called the Silicon Power 600x compact Flash Card and the thing has been around in capacities of 8GB to 32GB already. The latest update to the line brings a new 64GB capacity to the family. The memory card promises file transfers of up to 90MB/s. The cards use the ATA interface and consume little power when in use.
The new memory card supports 8-bit and 16-bit host data transfer. It also supports PIO mode6 / MWDMA4 / UDMA6. The memory card also has ECC and wear leveling for longer life and less errors. Pricing and availability on the new card is unknown.
