Still using CompactFlash? Lexar now has a 600x card that'll deliver a minimum sustained write speed of 90MB/s - and that's guaranteed, the company said.

Of course, you'll not only need a device capable of operating at that speed - look for UDMA 6 compatibility - but also $500 (£328) to shell out for the card itself.

That's for the 32GB version - Lexar also has 16GB and 8GB 600x cards, priced at $300 (£197) and $200 (£131), respectively.

Lexar also announced an ExpressCard 34 adaptor capable of taking the 600x CF cards - and lesser ones too. There's no word yet on the pricing of this accessory, though. ®
