SD/SDHC Card Write Speed Tests

[Pietro Impagliazzo]

Note:

The card I bought on ebay DOES NOT work with 50mbps hacked GH1.

Only those I bought from B&H works properly. Most probably the one from ebay is rejected from QC tests.

Here's a good comparison: http://www.tomshardware.com/charts/s...hmarks,40.html
It's interesting that a cheaper Transcend Class 6 16GB card beats a Transcend Class 10 16GB card in 7 out of 11 benchmarks.
And that Sandisk Extreme is definitively fastest by around 30%.

Yes, and the overall winner, that Sandisk Extreme III is actually a Class 6 too!!!

There was no official Class 10 rating when I purchased my first Sandisk Extreme III 30mb/sec Class 6 SDHC card and it is faster than the current junk brand Class 10 SDHC cards like ADATA. My homebuilt 6 core PC has USB 3.0 ports on the front of my Coolermaster HAF X 942 case and I will be getting a USB 3.0 SDHC/SDXC card reader when I get a faster card but I really don't need it today since my Panasonic HDC-TM700 3MOS 1080p60 camcorder records 1080p60 clips on a 32GB Sandisk Ultra II SDHC Class 4 15mb/sec card without any speed problems. I have a GH2 coming soon and I will use my Sandisk Extreme 30mb/sec card in it.

Just bought a 16Gb Sandisk Extreme C10 30MB/s. Excellent card. Recommended!

I have just received my 32GB Sandisk Extreme 30MB/s bought on ebay. some reason I cant run HD Speed, it just not responding after write speed. so i checked it on atto disk benchmark. I am really dissapointed because write speed is 16MB/s nad read 18MB/s (my transcendt 16GB class 10 have almost same results). is it something wrong with card or I do something wrong?

I used this card last week for the first time with my GH1 and would occasionally get error message saying the recording was stopped because the card couldn't accept the speed. I don't have a hacked unit. If I figure out why, I'll up date this post.
