Axtremex's 128GB 800x UDMA7 CompactFlash card. Click here to visit the Axtremex website!The latest generation of professional digital SLRs are really starting to push performance of CompactFlash cards to their very limit, and to get their maximum benefit, you need a really fast card to match. At its highest full-resolution rate, the Nikon D4 can capture almost 180 megapixels per second, and the Canon EOS-1D Mark IV comes close, at over 160 megapixels per second. Even as compressed JPEG files, that's a lot of data being thrown around, and in raw format it's a truly staggering amount. (A single D4 raw file can top 25MB or more.).

Flash card heavyweight Lexar has a solution on hand, in the form of its Professional 1000x CompactFlash card lineup that was announced back at the Consumer Electronics Show. Testing recently by our friends over at Rob Galbraith Digital Photography Insights found the 32GB variant to offer 129MB/second real-world read speeds, and write speeds just over 65MB/second. (Lexar suggest a maximum sustained read of 150MB/second, and doesn't state a sustained write speed in their literature.)

Right now, the Professional 1000x lineup tops out at a 64GB capacity, though, trading one problem for another. You can write data to flash really quickly, but the lower capacity means you'll capture fewer shots before you need to change cards. (There's a 128GB variant on the way, but it's not slated to ship until May, with a price tag around US$900.)

UK-based Axtremex Technology has just announced the release of an alternative that sacrifices nothing in terms of capacity, and comes with a significantly more affordable price tag. The Axtremex 800x CompactFlash card line have claimed transfer rates of 120MB/second read and 95MB/second write, while the 800x Plus line has a claimed 120MB/second for both read and write, although the company doesn't state whether these are burst or sustained speeds. The company's US distributor,, is now offering the 800x variant at US$400 for a 128GB card. That's quite a savings over the Lexar card that's on the way, although we've yet to see how the Axtremex card's performance bears out in testing.

More details in the press release below, and on the Axtremex website.
