Lexar Media on Tuesday announced the release of its Professional 600x CompactFlash (CF) memory card, which allows for 90MBps transfer speeds using the UDMA 6 standard. With the announcement, Lexar is the second manufacturer to offer such speeds in a CF card, as SanDisk already offers a 90MBps product range. SanDisk offers up to 64GB capacities, while Lexar makes 8GB, 16GB and 32GB cards.
