I feel your pain…same thing happened to me…just FYI, 32GB is SDHC (64GB and above is SDXC)…i am currently in the process of RMA with my latest SanDisk Extreme SDHC card. I purchased from an authorized dealer, and after experiencing (and measuring with ATTO) the slow speeds, went through a very quick, thorough email convo to confirm my findings. Do yourself a favor and send an email with your concerns to SanDisk. They will follow up quickly. After sending the slow card to them, they say I’ll be receiving the new correct card tomorrow. Fingers crossed
My guess is HUGE amounts of confusion over product IDs…there are at least 3 new product IDs for the newest cards, with little to tell them apart at first glance. And there are slight differences on the cards themselves, even those with similar names and speeds. The website is out of date, which should be a HUGE embarrassment as well. If we are confused, you can bet the production facilities are scratching their heads too. Who knows what they’re sending to the retailers?
It’s time for SanDisk to rethink the naming convention on their cards…why not just SanDisk Extreme32 and Extreme32 UHS? Anyone with half a brain can infer there is a difference, et voila! No more confusion…
Anyway, best of luck…hope they get your card troubles sorted out!
