SanDisk Extreme Pro 64 GB 160 MB/s CompactFlash Memory Card - Black/Gold/Red

Very good. Fast. Cheap.

Works perfectly not a bad size a bit pricey but works fine on my face one back

I have been umming and ahhing about buying this card for some time. Immediately you think " yes, I need more memory for my camera!" More is better, yes? Well, not always. There is always the temptation to buy the biggest you can. But, one thing anyone who uses memory cards for a while will tell you, if they go, they will always go at the most inopportune time. Sometimes its better to buy smaller cards and then transfer them to and from your Camera (I use mine in my Canon EOS 50D) so you in effect 'don't put all your eggs in one basket.'Now, that being said, this card is seriously fast and I can squeeze in more than 999 x 15mgb raw files and included Hi Rez Jpegs too. I can achieve a burst speed of 12 images a time before the camera has to pause to allow the card to write all that information. Even then, I only have to wait a second or so before I can 'machine gun' another set of images. Now, I am not in the habit of firing my camera around like machine gun :) but its nice to know I can, if I want to.I am going to be buying another one of these cards again very soon simply because at the price I bought it at, it was an absolute steal!

I've used SanDisk for years now, thought it was time to upgrade my old 8Gb card to a 64Gb. If this one performs like my old 8Gb card I'd be very happy. My old card has been all over the place, Scotland, Wales and places in between. Even in my old camera that fell over into a waterfall and snapped the lens off. The card got soaked whilst on and not only did it carry on but retained the images already on the card. The write speed on the new card is noticeably faster but that's expected as the old card was only 60 Mb/sec. A good price for the size of the card, feels well built, as far as a card can be. We'll worth the money and thoroughly recommend SanDisk.

Bought these before no problem

Had a Lexar card that failed in my camera. Fortunately my camera has a second card so I didn't lose anything, but I was on holiday when it failed and so very inconvenient. I replaced the Lexar with this card and am very pleased with it. It has the speed I need for my D810. I have 3 cards which I rotate and since I purchased this card I have taken about 16,000 RAW photos, each about 45mb so every card is well used and been re-formatted numerous times. All without any issues so I have to say I am completely satisfied with this card.My camera has an SD slot as well and for convenience I usually use those cards for copying off photos as my tablet has a built in SD reader but not a CF.

I,ve always used sandisk CF cards and their reliability has been spot on, any owners of the very fast canon 7d mk2 will know this camera needs cards with fast write speeds, i,m glad to say this card is perfect for the 7d.After running tests with my older cards there was a massive difference, the buffer would empty in just a few seconds, the older cards would take upto 40 seconds.With the buffer full i was able to still fire the shutter the continually around one shot per second, that,s around 30 shots before it,s buffer is full, a 3 second burst.Another great card from a top make, buy with confidence.

Super fast data transfer, downloaded RAW 600 images at roughly 20mb + per image in about 7 minutes. One word of caution, make sure you use a decent card reader, like the Lexar USB 3.0, as my old one corrupted the files on transfer. The images were fine on the card and in the back of the camera. After further investigation (something you might want to know if you ever see your images with 'blocky' colours across the image on review on your computer), it was a loose pin in my old card reader which caused faulty transfer of parts of the images.Using the Lexar reader, every image was intact and correct. Therefore 5 stars for the card as it did it's job and in blistering time.
