B&H delivers in excellent time, have just received CF card today, had to be formatted in camera before it would show on computer, took 22 minutes to copy 25 images to desktop file, very slow for a high speed rated card, images are from Canon 5DMK4 so they are large but lesser cards appear to copy...

I popped it in my 5D Mark III along with my SanDisk 64GB SD card (which I am going to make my back up as I shoot simultaneously) and set the capture to RAW (CF) + JPEG (SD) and I can just tell that the speed makes a difference. I am just assuming at this point that this is going to last forever.

Great quality and very fast

Durable; Great Picture Quality; Lightweight

This is the third of this type I have bought and they have proved to be reliable for video work. In particular they are easily fast enough to record 4K 50p video continuously, although they may not cope with the very high bitrate 4K modes in the latest DSLRs.

I bought the fastest Compact Flash memory that I could find for use in my newly purchased Canon 5D Mark III. The Sandisk Extreme PRO does not disappoint with its 150mb write speed (160mb read). It flushes the camera's buffer in mere seconds allowing higher burst mode performance.

I'm a fan of Sandisk. Their products are just great and this one is really top. With amazing writing speed and all. Great price for the card. Love it.

Used it in my gopro hero3 black for a year. It hasn't filled up yet because it can record video through all three of my batteries at 1080p, 60fps. Very happy.

Great storage capacity; Dependable

It was a little bit of a premium price; being on the leading edge of capacity last year

I've only had this card for less than a month and it is what I was looking for. I'm using this card for my Samsun S5 phone. I like to keep photos and video that I take on my phone so I could look things up or share with people so I don't delete too many things.

This works in my GoPro very well, very fast. Not sure why this other review give it only 3 stars. I can see the price has gone up since I bought mine in August of 2014. I guess I really got a deal at $49. I wish they were still that price as I need another one.

These, physically, amazingly small cards with, nevertheless huge capacity are terrific. My Samsung S4 phone now has now been upgrated to a total 80gb of memory which means I can continue to add programs photos and videos almost ad infinitum.
