Lexar unveils new UDMA 6 CompactFlash cards

Lexar follows close on the heels of SanDisk's announcement of its 90MB per second Extreme Pro CompactFlash card with its own player, the Lexar Professional 600X. Like SanDisk's, these expensive, ultrafast cards aren't for everyone; as detailed in the Extreme Pro post, you really need to be shooting with a fast, high-resolution camera recent enough to support UDMA 6 or frequently downloading lots of files with a fast reader to see the benefit.

I repeated the casual testing I did with the SanDisk card, and while the Lexar seems to be faster overall than the SanDisk, there are two things to keep in mind: different capacities will frequently perform differently and Lexar doesn't make the same durability claims or seem to invoke the error-correction algorithms SanDisk touts; the latter probably add some performance overhead, and might be a valuable trade-off for some shooters.

Like SanDisk, Lexar is also releasing an ExpressCard reader, which is required to get the maximum download speed--both manufacturers claim they approach 90MBps--out of any of these cards. (I had a prototype version of the reader to test, but stability issues prevented me from deriving any meaningful results.)

One digression: Watch out for speed claims made by both of these manufacturers, who've been making their comparisons versus 45MBps cards, thereby exaggerating the benefits. For one thing, it's a bit disingenuous to assume that potential buyers of these cards don't already own the most recent fastest versions available. Even if you don't accept that assumption, it's frequently true that the most cost-effective solution isn't the fastest option available but the next best, and the more appropriate comparison you should be making is against 60MBps cards.

Unlike SanDisk, Lexar doesn't have an imminent 64GB option, just 8GB (US$199) and 16GB (US$299), available this week in the US, and 32GB (price to be determined) slated for November shipment.
