I just dicovered that some of the faster SD cards, e.g. "Ultimate" from Transcend are MLC (Multi-level cell) as opposed to SLC (single level cell). http://ecx.images-amazon.com/images/I/71ooxNtTTTL._SL1500_.jpg
Panasonic also explicitly mentions SLC vs MLC in their lineup: http://panasonic.net/avc/sdcard/industrial_sd/lineup.html So, I wonder if all fastest cards in the lineup for other manifacturers are also MLC (e.g. SanDisk Extreme or Extreme Pro?). I was unable to find that information about SanDisk lineup. Does anybody here know that? >From what I know, MLC are cheaper and can be faster than SLC, but have short[er] life-cycle (number of rewritings). see e.g. here: http://www.oempcworld.com/support/SLC_vs_MLC.htm On another hand, I am not sure if that matters. I am thinking, how many time each of my cards gets completely written-over. I guess, roughly about once a month (at most). So, even with the endurance of 10k cycles, it should be sufficient for about 5-7 (or even 10) years that I expect to used the card. Any thoughts on MLC vs SLC in SD cards? In the past months I had two cases of a glitch on two different cards (one - SanDisk, the other one - HP), so, I am a bit hesitant to rely on those. Hence, I am considering buying a couple of new cards.
