Excellent Memory Card 9/8/2018 7:17:58 AM

Pros: - Very fast
- Large capacity

Cons: - The price has come down about 25% since I bought them last summer

Overall Review: I bought two of these for my DSLR for a trip to Iceland. They handled all of the burst mode I threw at them, and I didn't have to delete a single picture.

So far, 100% lives up the specs (and cost!) 8/3/2018 2:39:42 PM

Pros: - Fast
- Reliable (so far!)

Cons: - A bit expensive; however, if you want something that works you gotta pay for it.

Overall Review: Using two of these in my new Nikon D750 currently configured as "Mirror/Backup" so the images and videos are written to both cards at the same time.

The camera performs 100% to specs, and I've max out that bust-mode buffer plenty of times to know! The cards are 100% transparent to me and function exactly as describe.

I absolutely would recommend, and buy again!

Overall Review: Generally I go for U1 speeds, they tend to be less expensive but this time I wanted something that will Write at much faster speeds.
The Sandisk U3 is far better than I expected. From previous experience with a U1 which wrote at 40MB/s max, it was annoying that the Writing speeds would fluctuate so much that it would paused for seconds, pick up, pause and so on.
The Extreme PRO starts at 74.89MB/s and does not fluctuate ONE single bit, it will go as high as 83MB/s (although it's says up to 90, but haven't seen that yet), but never blow, it's so nice to see that this thing/speed do not go down at all, it definitely writes much faster which to me is perfect because 90% of the time I'd change my mind and end up writing to the card and in less than 3 mins it's done, whereas before I wasn't sure if copying files to the card would take more than what I had to spare, in terms of time.
It doesn't matter how many folders I copy to and files, the speed never drops. It's a great card and I'd definitely recommend it, even if it cost $24 more than my previous card and also the reliability of SanDisk cards is pretty high from my experience.

Extend local space on my Yoga 2 11/2/2017 6:06:55 AM

Pros: I wanted a removable drive that I could store development files for my Lenova Yoga 2.

Cons: it sticks out a lot! So I picked up a low profile USB thumb drive, a lot better and can just be left in the machine.
