Memory card speeds for HD video on D3200
Since I need more memory to handle all of my D3200's megapixels, I'm trying to decide which level of memory card to get. I typically get fast SanDisk cards. I see that you can get the Ultra line, which looks to be very fast -- class 10 / 30mb/s . From my reading, it looks like this should be fine for shooting HD video (which I am assuming is the thing that would require the most speed of anything that I can do with the camera). Have any of you found any reason to want to take the step up to the pro line, with its 95 mb/s?
By the way, I should say that I probably won't be shooting a ton of video, but I'd like to have the capability to do that well.
Also, if you think I should move away from the SanDisk offerings, let me know. They have been a reliable brand for me, but maybe there are some cost savings or better quality to be had.

I went the pro route because I am shooting flying birds using continuous mode. Point the camera just to the side of the feeder and as soon as I see movement, I fire a burst. At some point the buffer has to write to the card. there have been times when a bird has flown in and when he landed, all the other birds scattered. I got him coming in, but missed all the action as the rest scattered because the camera was writing to the card. I seem to be able to fire the next burst sooner with the faster card. (by the way, I'm using a d5100, but I would expect the situation to be the same with your camera.)

Do you not think an ultra-level card could handle that? I have to think that it would be up to the challenge if it can take HD video and has class 10 speed.
By the way, as I am doing my research, I'm doubting whether the huge rates that SanDisk advertises are anywhere near the speed the card actually provides. If that is right, I guess the question is whether all of the advertised speeds are equally inflated, so that each level up is actually faster than the previous one (just not nearly as fast as advertised).

You need to consider the equipment the card is placed in. SanDisk is reporting their top speed with a card reader or other device that operates at that speed or better.
If you camera's bus speed between the camera's processor and the card.
If your camera can only deliver data at 28 MegaBytes will not record data to a 95 MegaByte card any faster than 28 MegaBytes. SanDisk rate the cards with the "Speeds up to" because of the possible equipment limitation.
Because card readers are relatively cheap, you can get a benefit from a faster card when using a new fast card reader to transfer the images.
Look at Rob Galbraith Nikon D4 SanDisk Extreme 60MB/s 16GB Burst is 74MB
Nikon D3s SanDisk Extreme 60MB/s 16GB has a burst speed of 67MB.
Look at the internal and external identifiers, they appear to be the same card in different cameras.

So I wonder how fast a D3200 can deliver data? I'm not very concerned with delivering data to a computer from the card, apart from the fact that I'd like it not to take a ton of time.

I picked up a couple sndisk cards 8 gig class 10 95 Mbs speed, 19.99. Seemed like a good sale for a fast card. They worked well I save them for when I want a lot at once. In my I timed very subjective trial I thought they cleared the buffer a bit quicker. Never tried them with video but they are the ones I will use. I have never had a problem with the 30 or 35 Mbs cards I have.
