From what Prometheus says class 10 are more likely to fail, so I would rather prefer to stay off [a SanDisk extreme class 10 card, remark].
(...)
There are also "Extreme III" variants, which nobody tried yet, apparently. But they seem to be faster ones, therefore more eligible to not working with ext2?
If you read her statement again carefully you can see that she just presented symptoms and correlations while not implying a definite cause (instead suggesting a possible cause): "[...] several people, [...] are encountering problems using fast cards (Class 6 and Class 10) with the Pandora at the moment, and in some cases this extends to using particular file-systems on those cards" [1].
So this statement does not necessarily mean that class 10 cards generally have problems with ext2. At least from my non-representative experience, it's very unlikely that there's a causal connection between "high speed class" and "file system problems" (which doesn't mean that there might not be a connection - it's simply unknown to us here at this point). Instead, I guess this might be a problem in either the Pandoras software or (*gasp*) its hardware.
That being said, as Prometheus said there ARE indications that the combination of /some/ higher class (class 6 as well as class 10) SD cards with a (particular kind of?) Pandora does lead to problems. While there are other factors that are not absolutely clear (which, amongst others, may include that lower class SD cards may have similar problems but the low class rating makes users believe that the cards simply can't stand a lot of stress; or that it's possible that the increased number of problem reports covering this SD card problem is caused by
selective perception), it seems likely that parts of the interaction between some kinds of SD cards and a (particular kind of?) Pandora is causing this particular kind of problem ("some kinds of SD cards" /
might/ mean higher class (class 6 and class 10) SD cards, but may also mean some other kind of SD card that coincidentally correlates to "higher class SD card")
Also, from what you say "Sandisk Ultra" are not going to work?
You mean because the changelog says that I replaced "SanDisk \"Ultra\"" with "SanDisk \"Extreme\""? If so, then no - I had simply made a mistake. I didn't mean to imply anything about SanDisk Ultra, it's simply that I would have written SanDisk Extreme in the first place hadn't I mixed up the brands.
There are also "Extreme III" variants, which nobody tried yet, apparently. But they seem to be faster ones, therefore more eligible to not working with ext2?
By "SanDisk \"Extreme\"" I referred to all SD cards of the SanDisk Extreme line - it's not the immediate speed that makes the "Extreme" line from SanDisk (no matter what iteration), as well as some other brands of better SD cards, different from average SD cards; basically it's how well they handle stress (physical stress, excessive small "random" writes, and similar things).
Also I looked for Panasonic, but they are not sold in Europe at all - no chance to get one.
At least in Germany you can get them in "Gold" and "Silver" flavors in bigger electronics stores, typically somewhere at the digital camera section (even if other places of the store are full of SanDisk). amazon.de also has them, but I have no idea if you can order them from amazon when you're in another country. Quite a few photographers are using Panasonic cards, so maybe some stores around you that have good digital cameras will have them.
I would have never suspected that buying a ext2/3/4 working 32GB card would be such a PITA. Could you help me a bit with this?
People may be able to give non-representative experience reports, but unless we collect quite a few of them and correctly use comparable benchmarks and testing methods (which, as you now know, is very easy to screw up given the complexity of the situation), you can only make an educated guess. As you know,
I already did that, and even though I did some research on SD cards in general, my suggestion of cards that I typically use for stress-laden situations may currently not work very well for the Pandora if there are indeed problems with higher class SD cards. Someone has to find out the exact cause for these problems (that would be the best solution). Depending on when and if that happens, and also depending on what the actual cause is, you will be better off with either a slow or a fast card.
This is the kind of situation that makes me wish that "luck" wasn't just a word for not yet analyzable occurrences.
