I've never used the entire card yet. It's fast. It's big. I've got a Sony a7rii and you need a big card. I shoot in raw and jpeg and still have not used the whole card before I download the pics. (((For Sony a7rii users...this is the fastest card for the camera!!))) This card works. Don't get a fake one. Buy it from Best Buy and you know it will work. I got one before from the Amazon and it did not work. Not saying all on there are fake. But why take a chance. Best Buy will match Amazon and camera store sales!!! Check for a lower price and get it at Best Buy. I did save a lot by doing that.

I bought the SanDisk Extreme Pro 256GB SDXC to use with my DSLRs that require the processing speeds that the Extreme Pro SDXC offers. The SDXC memory cards are used widely with other peripherals which made it an easy choice for me to use when it comes to data storage and transfer options.

I have been using this as a storage drive extension in my laptop. It is great to expand storage capacity in laptops with a SD Card reader slot. I keep it installed all the time and it's way cheaper than upgrading my SSD (& easier too!)

Exactly what I needed for my new 4k video camera. Never ran out of space!

One can't go wrong getting a Sandisk memory card and this one is no different. Great for 4K content.
