I switched to Sony from Nikon last year because of a few bad experiences with Nikon customer service and was not expecting to run into the staggering price tag for CFexpress-A cards when CFexpress-B cards are twice as fast and half the cost. Further, I was hoping to see type A cards decrease in price as the platform increased in popularity, but this hasn't even begun to occur. I could justify this price if, and only if, Sony managed to crank the read/write speeds up high enough to validate it.I bought a couple ProGrade 160gig cards on special for when I need to shoot at higher cycle rates, but otherwise, sticking to SD cards.

CFExpress Type A is slower than Type B but more expensive. This is already common knowledge for its users. However, Sony only put one NAND flash into the 80GB instead of other cards that have two NAND flash chips.That means it only achieves half the speed of the higher capacity cards while having the same $/GB unit price.Sony should be ashamed of putting this product out with the rated speed sticker. Extremely disappointed.

This is a great card, albeit expensive, too expensive. With the A1 camera, the write speeds are so fast. They make a great combo. I only wish the A1 could use Type B cards. I highly recommend the 80gb or 160gb cards to anyone shooting wildlife with the A1. The investment over time will be worth it.
