SD card speeds - would this be fast enough?

I haven't tested this so far, so wanted to ask you guys: what card speed would be enough for burst shooting and moves in full format on Panasonic G5 or other m4/3 cameras?

I'm about to buy one of these:

16GB Kingston SDHC UHS-I Ultimate, which is 60MB/s read and 35MB/s write - £11
32GB Kingston SDHC UHS-I Ultimate, which is 90MB/s read and 45MB/s write - £20

Both are named same, but 32GB is faster - apart of capacity - would I notice any speed difference (clearing camera's buffer faster etc) between these two?
Or is it really not that important and I can go with slower one?

There is also one in the middle of these two - 32GB SanDisk Extreme SDHC 45MB/s read/write for £20

Second question - Kingston or SanDisk?

PERSONALLY, I only use SanDisk but that's a personal choice rather than one made for scientific reasons! If (/when?) a SanDisk one fails, I may switch to another brand.

As for the speeds, I'm not sure any of the faster cards will cause a bottleneck in real life.

They used a SanDisk Extreme Pro 95MB/sec UHS-1 in the testing.

*Note: Buffer clearing times measured with a SanDisk Extreme Pro 95MB/sec UHS-1 SDHC card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode. ISO sensitivity and noise reduction settings can also affect cycle times and burst mode performance.

theres the transend card with a red sticker that does 45w/85r and is cheaper :)
i picked up a 7dayshop 45meg/sec card thats ment todo more but not tested it yet :x
 
TRANSCEND 32GB SD CARD (SDHC) - CLASS 10 / UHS-1 85MB/S
£16 @MyMemory
Had three 7dayshop cards fail in last six months. Wouldn't trust them at all. Only cards I have ever had fail on me
 
Thanks guys.
I went for Sandisk 45MB/s - will see how it goes.
Sounds like buffer clearing is something that will last, but as of burst shooting 45MB/s should be fine and not slow down the camera.
 
sandisk are pretty solid but I have had a couple fail (not mid shoot!)
their customer service is great, but you have to send items to the czech republic for RMA. not cheap in terms of postage!
I would have gone sandisk or the 31gb kingston.
I don't trust transcend cards, the one I had was dog slow! sandisk sometimes have specs that don't look at good but imho, they hit them. other manufacturers seem overly optimistic.
 
my transcend matches its speed claims, but they do also make low end slow n cheap cards
