Sony has a long history of pushing their proprietary formats for many things that otherwise (and outside of Sony) become more or less standardized. A good example of this Sony approach is their Memory Stick format that has irked quite a large number of Sony fans who wished at times that the Japanese company might be a bit more lenient and include SD memory card support in some of their devices. Well, it didn’t happen this time, too. At least, not for SD Card format.
The Lexar Professional 600x Series compact flash card is aimed at pros that need the fastest CF they can get their hands on. The ever increasing size and speed of built in camera buffers and FPS demands a reliable, fast solution; the 600x series from Lexar is just that. Boasting a minimum sustained write speed of 90 MB/second, you will find it fast enough to keep up with the fastest DSLR’s on the market today; such as the Nikon D3X, Canon EOS-1Ds Mark III or any UDMA supported camera for that matter.
