Memory card i have tried

[monkey1]

So far, i have try 4 types of memory card:

1. Sandisk ultra class10 16GB --- 2 hrs log data only have 400,000 data units, 100MB. DATA LOSS --- cannot use

2. Transcend class4 8GB --- imu_MAG will occur spikes, like a magnetic influence ----- cannot use

3. Sandisk class4 16GB ---- same with transcend class4 8GB problem ------ cannot use

4. Sandisk Ultra class10 8GB ---- Everything show perfect. ----- Should use this one.

one more things, if you want to format your sdhc card, pls select 32kb block size.

Class 10 was recommended from the start.
We'll obviously also need to recommend not to use cards with more than 8GB.
Even a 4GB card would be sufficient for the loggings. I'll update the Wiki and add a note.

The lower the capacity the more robust the SD cards appear.

Unfortunately it's getting harder to find < 16GB cards. I think the shrinking price difference between 8 and 16GB cards (a few $s in most cases) is driving the smaller ones off the market, even though they're typically a bit faster than the bigger capacity cards.

They're not hard to find - you can get them nearly everywhere: Amazon, Ebay, local shops for ~10$/€
I think that users tend to buy a higher capacity since the price difference is pretty low. 100% more capacity for a 50% higher price sounds convincing.

btw: I've added a recommandation for <8GB sd cards to the Wiki - just in case...

In my local store they sell lots of 8GB class 10 cards...

Sure, you can still get them, but there are significantly more choices of 16+GB cards now than smaller ones. On Amazon there's basically 2 8GB choices ($10 and $25) vs > a dozen 16+GB (that are actually sold/shipped by Amazon). There are a few more options over at Newegg, but they're shrinking. The outcome is inevitable. The good news is that higher capacity cards are getting faster.

Hi,

I use a Lexar HS 16GB class 10, and it sounds good for me.
