Yes it is -- But as Class 6 spec = "at least 6MB/sec", there are faster Class 6 cards. There was a poster on another forum who tested the write speed of a K10 and it was a bit over 16MB/sec. With my K20, a 4 GB Sandisk Class 6 Extreme III 20MB/sec is more than twice as fast as a 4 GB Transcend Class 6 SDHC which has been tested at about 7MB/sec, so my best guess is that the K10 and K20 write at similar speeds. Another poster in still another forum spoke to a tech guy at Pentax and was essentially told that he'd be wasting his money seeking out a 30MB/sec Extreme III because his camera would perform essentially the same as with a 20 MB/sec card.
This may sound trivial, but write speeds will effect number of shots at max continuous speed and the time that it takes before a shot can be displayed on review. This must be important to some people, since so many seem to be so disappointed in the FPS rate of Pentax cameras. . .but few seem to be interested in this performance aspect of their cameras.
