I found this on another site and thought it very useful.

I have already a 32MB Lexar with no problems in em1.2. After reading this, I've ordered another 64GB also from Lexar.

I do expect not to have compatibility problems... but clearly the recommendations from Olympus does not seem convenient.

Ok! I'll ask... How are 64GB cards faster than 32GB cards :confused:

Well... actually it's not faster, just I needed more space, for em1.2 32MB is short, pro mode, high res, focus bracketing, etc... eats a lot of space.

According to the table in the link, the 64 Lexar is 2.6% faster than the 32 and the Transend 64 7% faster than the 32...

I'm going to guess that it's a circuit density thing... *zzz

Here (https://www.dailycameranews.com/2017/02/sony-fastest-sd-card/) is something to consider, but it's expensive. :eek:

I've learned with this camera test that we need to see what is the real speed in the specific machine, as it's quite sensitive to the reader. There is a recent Lexar's independent speed test that shows 2000X models having write speeds over 260MB/s (or so), however, in this camera test, the same cards are showing 100MB/s less speed. I'd expect the same happen with all other vendors.

I've got from Amazon the Lexar 64MB 2000X, rev.C. No problems observed after a quick test (hig res, focus bracketing, pro capture).

FWIW I have been using a Lexar Professional 16GB 1000x SDHC II with no problems. I think I paid around 24 from My Memory.

Also, FWIW. I have been using Lexar 2000x 64GB 300mb/s since december without any problems.

Unless they tested multiple examples of each card and averaged the results small variances can pretty much be ignored. You could test 5 identical cards and get a spread of a few percent or so in the results.
