Plus, for some reason, the Sandisk Ultra would dismount itself from time to time for no apparent reason causing me to have to shut down the phone, reseat it and restart my phone! This happened multiple times at the least opportune moments. Hopefully, this will not happen with the Samsung Pro, but I haven't had it long enough to confirm yet. I will update this if that happens.
Update 5/22/2013:
I've had the card for a month today and so far I've had zero issues. The card has not dismounted itself even once. I could not be happier.
Update 7/8/2013:
Still zero issues in my phone. Just purchased a second one for use with a GoPro HERO3 Black Edition . Got it on June 20th directly from Amazon for $50.99, which is the lowest price I've ever seen for the 64GB Samsung Pro so far.
Update 2/1/2014:
I now own three of these cards and they have all been fast and worked flawlessly. The one in my phone has never, not even once dismounted itself like the Sandisk card did. I'm using another in a 2014 Samsung Galaxy Note 10.1 and the third in a GoPro HERO3+ Black Edition .
If you have camera that requires class-10 card, and you need high capacity in micro-SD format, I can highly recommend this one. It's slightly more expensive then similar SanDisk Ultra card, but unlike SanDisk Ultra, Samsung Pro works :-)
Some numbers. Test of write speed (writing out 1GB of zeros to the card):
$ dd if=/dev/zero of=test bs=131072 count=8192

iostat shows write speed to be more or less constant throughout the write:

When shooting at 2.7K / 29.97 fps in Protune mode, it records at 45Mbps, which is higher than the SanDisk cards (which it dials back to 35 Mbps). This card, at that resolution, holds just over 3 hours of footage, which is about 30 min longer than my battery lasts, so I have never had an issue with space, as long as I dump the card when I charge the battery.
Transfer speeds are fine, and about what I have come to expect from a micro SD card. If I copy files with the card mounted in the camera, I get about 11 MB/s, but that is mostly a limitation of USB 2.0. If I use a USB 3.0 card reader (I have an Anker Uspeed 8-1, which cost about $8), I average about 38 MB/s. In simple terms, I can dump the entire 64 GB card in about half an hour, which is, again, faster than it takes to charge my battery, so it is a non-issue for me.
My only complaint (and it is not enough to knock a star off) is that it does not come with an SD Card adapter, as many micro SD cards do. So make sure that you either have a micro SD card reader or are willing to read it directly from the camera.
