Billed as the world's fastest SD cards, the recently released SanDisk Extreme PRO SDHC/SDXC UHS-II memory card series uses the latest high-performance SD specification, UHS-II, to offer up to 280MB/s (1867X) read transfer speeds for optimized post production workflows and up to 250MB/s (1667X) write...

NOTE: This "two card kit" is two different speed cards! Why B&H would want UHS-II and UHS-I cards in one pack together I do not know. Because the url only mentions the UHS-II and the main picture only shows UHS-II it is quite reasonable to assume that you get two of those cards. But you don't.

Received the product faster than expected

Bought this and tried it in my Canon Vixia HFS10 HD camcorder. Cannot even record at the higher MXP or FXP settings (24 or 17mb/s), best it can do is XP+ at 12mb/s. Needless to say this is getting returned!

16gb that's about it

Nowhere close to the claimed 30mb/s speed; More like 12mb/s; EXPENSIVE

I always use SanDisk memory for all my gadget data storage and never had any complain. The access time or data transfer is quite fast, more than average of other memory. Price might be slightly higher, but for performance it's not a problem.

good price

Its great and fast! Just what I wanted! Holds a lot of space and the upload was so fast! Thank you!
