I would like to by two 32gig cards. Would these Transcend 32 GB Class 10 SDHC work? These cost about $30 eachhttp://www.amazon.com/Transcend-Clas...ref=pd_sim_p_3
Or, should I play it safe & get these: SanDisk 32GB EXTREME SDHC Card Class 10 45MB/s for about $40 each?
This is one of those areas where spending extra money does not get extra performance.
Ungerman pointed me towards some reading on SD Cards at Wikipedia.
Confusion comes up because the class ratings guarantee speeds in Mega Bytes per second. A class 10 is guaranteed to run no slower than 10 MB/s.
Our cameras' performance specs are in Mega bits per second. Page 129 of the FZ150 Advanced Manual states, at the highest setting, it is producing data at 28 Mbps. Converting mega bits per second to mega bytes per second explains why it says on page 20 you can use ANY class 4 SD card that runs at only 4MBs. Buying any Class 10 card,at 10MBs, gives you better than a 300% margin for speed!
A 1080p60 camera of any brand can't work fast enough to take advantage of any Class 10 card.
The difference between SD, SDHC and SDXC designations is about formatting and potential storage capacity, not speed. (Fat16, Fat32 and ExFat) Getting a 32GB SDXC is not better than getting a 32GB SDHC card. They are just formatted differently.
Making it more confusing is that the Class rating is a "minimum". They usually go faster in both read and write. And, the card makers can brag about faster speeds if they want to create a "marketing edge" to justify a higher price.
Most of us seem to buy Class 10 cards because they seem to be commonly available in sizes appropriate to what we do. For example on a three week trip I filled two 32GB cards only half way. So, my standard has become 32MB Class 10 of any brand for my three cameras.
If you want to test both speed and reliability, you can use a program called "H2testw" (It's German. Google it for a download.) It takes a blank card, fills it with dummy data and keeps track while doing it. Then it reports if there were any errors and how fast the card reads and writes. My collection of SD cards all passed.
