Hi Dhardjono
I see to get better results from the Sandisk Extreme Class 10 45mbps card than the 30mbps card but "officially" using the max bitrate of 24mbps (and it's usually lower sorta between 17 and 21) a Class 6 card is supposed to be more than adequate!! Unless you are shooting really, really long sessions I prefer still to use 16GB cards ... The longest shoot I ever too might be a 2 hour dance recital which has an interval anyway so a 16GB card still gives you 1 hour 37 minutes on the camera. Even if you don't use the relay function you can load up two cards and after an hour, just change over. If a card is going to start giving me problems and looks like it's going to fail I would rather toss out a 16GB card...then again the 64GB card is a lot cheaper to buy compared to 4 x16GB cards.

I have a question: does our OR can our camera format the cards exFAT or only FAT32?
If exFAT- then I think that card would be perfect. Otherwise I would stick to 16 or 32GB - depending on your needs.
If the price was right - $ per GB -- then I would consider it.
LCD4video had an awesome deal on 32Gb Ultra class 10 = $30 (seems like prices, overall, are dropping)

Not for recording, no. That card writes at 80 Mbps ( 10 MB/s ). That is way faster than the AC-130 or AC-160 can send it data.
I use the cheaper PNY 32GB Professional Series Hi-Speed SDHC Class 10 myself. While it is slower than this SanDisk Ultra at reading ( 20 MB/s compared to 30 MB/s for the SanDisk Ultra ), it is actually 50% faster at writing, and records at 120 Mbps ( 15 MB/s ).
There are different oppion here i also have my annual dance recital that why the 64 gig would be long enough recording time for 3 shows using simu rec, Maybe better get extreme or pny card for peace of mind. Also the new 1080 60p CUT DOWN THE TIME cause of the higher bit rate
Thanks for all replies

I only buy the newer Panasonic UHS-I cards. I have the USB3.0 reader and that is where the higher transfer speeds come into play. Recording speed is a non-issue, as others have pointed out, as these cameras don't write anywhere close to the highest capabilities of the cards themselves for Class 10.
Last week we were shooting breakout sessions all day on 6 different cameras. I plugged the Panasonic reader into my laptop, put the UHS-I cards in there and I was able to offload all the footage from the first 6 sessions (1 hour each) in a matter of just a few minutes, maybe 10 minutes total. Very fast. On my older cards (non UHS-I) and using just the standard built-in card reader on my laptop or a USB 2.0 reader, that would have easily taken about 10 minutes per card, about an hour for all the footage.
That's one major point. The other is that the Panasonic UHS-I cards are much better built, and can withstand a lot of abuse from dropping, moisture, shock, etc....they are very expensive but then so are refunds for lost footage from a damaged or faulty card that would have only saved me $75 at the time of purchase.
Here's the cards I use as sold on B&H: http://www.bhphotovideo.com/c/product/805156-REG/Panasonic_RPSDB16GB1K_16GB_Class_10_UHS_I.html
Here's the USB 3.0 reader: http://www.bhphotovideo.com/c/product/805158-REG/Panasonic_BNSDCMAB_UHS_1_Compliant_USB_3_0.html
If your laptop or computer doesn't have USB 3.0, you can buy an adapter (ExpressCard adapter for laptop costs maybe $15 to $20).
Those cards also have an application you can download from Panasonic that shows you the usable life of the card. All told, these cards will last you a very very long time even with frequent shooting. All the main selling points for these cards are also listed on the Panasonic website.

Scapsinger is right that these cards with the faster read speeds will transfer big files to your PC much faster, especially if you have USB 3.0
Older PC's can be easily upgraded with an adapter to provide a couple of USB 3.0 ports. However, many of these adapter cards require a power cable from your PC's power supply to be attached to them, and thus are a bit tricky to install. Some USB 3.0 adapters, however, require no such power cable. The one that I got for my PC is from Western Digital, and was super easy to install. Just plugged it in and that was it for installation, other than also having to also install the software driver for the card in Windows.
Here is a link to this Western Digital USB 3.0 adapter. Cost is only $27:

If you are installing a card in your Desktop system in order to get USB 3.0, then that card reader that Scapsinger is using will be rather awkward to use. I would instead recommend getting a unit with a USB 3.0 cable, so that the reader can be at the front of your computer and thus more accessible. This is a great card reader of that type:

His USB reader is ideal for use with a laptop, however. So if you are using a laptop, it would definitely be the better way to go.

The Panasonic USB 3.0 reader includes a cable, it's a couple of feet long, but you can always get a longer one if you need it (USB 3.0 cables only, using a USB 2.0 or older cable won't work). There are benefits to getting the Panasonic reader, since you can only use the Card Checker software to check the card life with the Panasonic reader.
Can you elaborate by explaining what you mean by "better results"?
I'm still amazed people don't know the difference between Mbps and MB/s.
Card are rated in megabytes per second (MB/s), whereas data rates are in megabits per second (mbps).
AVCHD is 21mbps, which is about 2.6 MB/s. So a 30MB/s card is more than enough to handle anything you throw at it, since it's the equivalent of around 240 mbps.
This is why I'm curious what better results you're seeing.

Data rates can be measured in either; it's just important to be aware of the units. But, more to the point, many people are talking about OFFLOAD speed of the cards, where we can take advantage of every bit/second the card can spit out. I have Class 6 and 10 cards, and don't see a lot more than 1 GB/min. I'd love to offload data from cards at the typical 240-300GB/hr a decent SATA drive will take.

The Panasonic UHS-I cards come a lot closer, I can get about 5-6 GB per minute with the USB 3.0 reader on those cards. Very fast.
