2013年10月11日 · Figured i start a thread about SD cards and ther performance as logged by H2testw. I figure 1 post per person and just update that one as you go along. Please post a good close up of the card and add H2testw result below. If you have results for simmilar cards allready posted by another guy...

Just because h2testw doesn't report any errors or something like CrystalDiskMark shows the average write speed across the entire card is good doesn't mean you don't have some blocks scattered across the card that for some reason write slow.

2013年10月11日 · The H2testw figures are in Mega Bytes per second so something like 8 times faster than required, which is why kamkar1 is puzzled over why the cameras should have any difficulty. I guess that none of the cameras use the UHS (ultra high speed) functionality and just use the basic SD interface which will be a little slow when you get above 40Mb/s ...

2017年3月9日 · Hi, I'm in the process of running a 128gb microSD through H2testw, Obviously it's gonna take about 3 hours but I wanted to show this first screenshot showing its progress and ask if the numbers point to it being of true capacity?

2013年1月27日 · I used the h2testw program to check it and selected "all available space (243,979 MB)" I clicked "Write + Verify" and it gives me a message that it will only test "243,979 MB while the total capacity is 243,980 MB..." When I go to convert 243,980 MB to GB, I get 244GB. What happened to the remaining 12GB?
