SanDisk - Extreme Pro 64GB SDXC UHS-I Memory Card

I have reached advertised speeds on a built-in card reader and a newer digital camera but there are a few things anyone should know when choosing a card. Cards with 32GB or less are SDHC and should work with most devices released in the last few years. SDXC will cover cards with higher capacities, such as this card in 64GB. This is an important consideration to Linux users since SDXC uses exFAT which may not work with your OS. If you have an up-to-date Windows installation or a recent Mac release you will be fine without third party software, though a firmware update may be necessary for your card reader if it's pre-'09. You will not achieve UHF speeds on a USB 2.0 bus - you will see a maximum 20-30MB/S depending on file size and other factors. On many host devices the speed gains are negligible during operation because of fast internal memory buffers - I can burst (9/s) an average of 15 shots in RAW+jpeg on my DSLR with a class 6 card, or 18 with this - so probably not worth the premium price for that gain alone. Video there is no difference since the class 6 can float the 20mbps required for 1080i on my camera. In other words, if you can get the extreme pro in 64GB for the same price as the extreme in 128GB, your money is probably better spent on the extreme, if not on a non-UHF card, which is to say class 6 or 10. It may be noteworthy that this card is waterproof and x-ray proof, but does not specify that it is magnet proof as other brands' documentation does. That said, Sandisk has some of the most robust built-in error checking features in the 'biz and other brands don't really compete in quality if you do some research. My advice is to make sure you can use the extra speed you're paying for - if you don't have a USB 3.0 card reader, a host device with USB 3.

I am starting out in the world of digital photography having upgraded from a point-and-shoot camera to an entry-level DSLR (the Nikon D3300). I wanted a memory card that was large enough to hold both RAW and jpeg 24.1MP photos from a week long vacation (I have my camera shoot both at the same time) and fast enough that my camera wouldn't slow down much when taking burst jpeg shots. So far, this memory card has more than served it's purpose. I was able to take well over 500 RAW+JPEG photos during my 5-day vacation to Niagara falls and the memory card was bout 1/3rd full. I didn't have any memory corruption issues and the card was fast enough that, when I was taking burst shots, the camera didn't slow down much and I was able to capture about 7 shots (2 shots more than the slower 80MB/s card that came bundled with the camera) before I was down to about 1 shot per second. Photos were pulled up at near-instant speeds on my camera and copying the photos off of the card (for processing on a PC) is extremely quick. The card is fast enough that I can even do basic edits on it without having to wait forever. You can get a higher capacity card for the same price but it won't have the same read and write speeds. For DSLR photography, I recommend getting a faster memory card. It will allow you to take more shots instead of waiting for your pictures to write to the card. I went from an 80MB/s card to this (95MB/s) and the difference is noticeable. 64GB seems like the sweet spot for capacity. You can take over 1500 24.1MP RAW+JPEG shots, that should be more than enough to get people through a week long vacation and then some.

Perhaps not the best storage size for all you 4K videographers out there, but let's talk about a slightly above-average 1080p, 24MP RAW videographer/photographer type of user. One SD card, no problems. This SD card is still very quick even in today's standards unlike the previous versions of this card running at below 80MB/s read speeds. When shooting in RAW 24MP, I am able to capture mostly what I need before the buffer comes hard and halts my work and even then, it becomes up to the camera to process these images faster rather than the card. In terms of 1080p video on a Canon DSLR, I used to be plagued with "movie recording has stopped automatically." With this card I face this issue a lot less and it usually only occurs due to some other issue these days. Transferring footage to my computer via USB 3 adapter or the built in SD reader on both PC and Mac is easy and fast. I used to wait 45+ minutes for older cards to empty from full, but this cuts it down to around 20-35 minutes depending on certain conditions. One very important thing to note, do not pay more than $40 for this card. Pros: -Cool color scheme -All the fancy weather protections -Fast transfer speeds in write AND read -Good build quality (I've had SD cards bend in half) Cons: -Very rare but sometimes my camera rejects the card -Otherwise no complaints on price and speed Thanks for reading my review.

This was the first SD card that I bought for use with my Canon 7D Mk II, & it worked flawlessly for over 2,600 JPGs while I recorded the RAW photos on my SanDisk CF cards. I also own a Canon 7D which doesn't utilize a SD card, but the MK II allows me to shoot with both cards, which offers several advantages. 1) Is the way that I used both cards, this allowed me to have a backup of the CF card's Raw photos, & 2) the SD card was used to take JPG shots, & that allowed me to send or give out a photo that didn't require post processing like the Raw shots, which I planned to do after returning home. I took quite a few multi-frame photos where I just held the shutter button down & it never missed a beat, it's fast. In fact, I just went & looked at some of the photos on the disk (as I've yet to upload them onto this computer) & they really are great, any that aren't would seem to be my fault. This is a 64 GB disk & even with 2,600 large JPG (& some video) files there is still over 40 GB of room for more. This review will be a twin to the 32 GB SanDisk CF card that I purchased at the same time! Capt_Jim

I have two of these Extreme Pro Sandisk cards, both with slightly different card ratings. Extreme pro 16gb class-10, U-1. Extreme pro 32gb class-10, U-3. Both cards are basically the same and are excellent! They work like a charm with my Canon camera. I often use speed burst and long exposures so this Sandisk handles smoothly! Download speeds are ultra fast and that's all that matters when it comes to moving digital data from card to computer. Who cares about write speeds, in reality how long it takes to get your images, music or video data to your workstation is what you should be thinking about.. we can't be waiting all night! Lol. The writing part of the card (digital data getting written/recorded from gadget to card) does exceptional, a camera's buffer system does the hard work (if using with a DSLR), so no matter how fast or slow a card is it will always work and work well! Very fast and performance is top tier! Will recommend!

I tend to 'over buy' on my storage cards. In this case I chose the Extreme PRO discs because they write extremely fast! 90/MB/s with a read speed of 95 MB/s. This means they are great for video. But I tend to take a lot of fast action or bracketed photos so I want the write speed to be fast. If I take a video here or there then I know I won't have an issue. I chose a smaller storage capacity (I got the 64GB) because you never want to max out a card and then something happen to that card and you've lost all of your shots. I will be traveling abroad for a month and plan to have a minimum of a card a day so will be able to keep a diary of sorts just through my cards (that will match up with my travel journal. SanDisk always puts out a great and dependable product. I highly recommend this card!

I use these cards in my Nikon D800 and D610. It definitely helps with the buffer speed if you use continuous shooting. Picked up two when it was on sale and saved $490.00!!! Below is a list of how many pictures that can be taken at different file settings within the camera: Large Files 6016x4016; 24.2 MP NEF-RAW+ JPEG FINE 915 pictures NEF-RAW + JPEG NORMAL 1,000 pictures NEF-RAW+ JPEG BASIC 1,100 pictures NEF-RAW- 1,100 pictures (Setting I use) JPEG FINE- 6,800 pictures JPEG NORMAL-4,000 pictures JPEG BASIC- 15,700 pictures THIS IS THE LARGEST SD CARD THAT CAN BE USED IN A NIKON DLSR CAMERA. ANYTHING ABOVE 64GB WONT WORK.

Although pricey, the 90MB/s write and 95MB/s read speed of the Extreme Pros makes it ideal for HD Video recording. My Canon EOS 70D DSLR is especially picky about needing a very fast SD card for HD video recording. Lots of reports of video recording stopping inexplicably despite using a class10/UHS-1 card. Turns out the classification is not precise enough as it looks like the SD card needs to be able to sustain at least 40-60MB/S write speeds. The SanDisk Extreme Pros have proven reliable where the SanDisk Ultras have choked from lack of write speed. No problems with still photos -only with HD video recording on the Canon EOS 70D.
