We have 8 Lexar 1000x 32gb cards between us all bought before the sale. The cards went to Alaska and was used with 1Dmk4's with high speeds. The eight used had now problems. Cards have been used since with no errors.
We do have 2 more 2 packs on order with B&H but supply is not there yet. Maybe the next batch will be different??
I am confused, they did or did not have problems in Alaska?

Pretty much all NAND that's out there is and has been MLC for a while and it's all fab'ed by SanDisk/Toshiba, Intel/Micron or Samsung. It is perfectly reliable. In fact it wouldn't surprise me if Lexar bought their NAND from SanDisk. The difference in SanDisk vs. Lexar is not the memory cell, but the packaging and memory controller and the logic that runs the controller.
Lexar is a brand name belonging to memory maker Micron. Why would they be using someone elses memory?
I also had a Delkin 1000x UDMA 7 card that failed on me (first corrupted some images with the pink lines, also lost a whole series of images). It was included with my 1DX purchase. Maybe the UDMA 7 is not ready for prime time? Or are some makers just inferior?
BTW, "CardRescue" saved my 350 vacation images that I thought were lost when the Delkin card failed. Worth twice the price just for that instance.
It is not uncommon in semiconductor industry to buy something you make yourself from someone else if it ends up being more economical for a particular application at a given time. It is the fast-moving dynamic nature of the industry. For e.g. Canon make all kinds of image sensors themselves but nowadays they buy CCD chips from Sony for their lower end cameras.
I don't know if the NAND that goes into Lexar pro 1000X cards is fab'ed by Micron or someone else. It's possible to figure out by breaking the package and figure whose name is on the chip
I know better than to get into a "my brand is better than yours" on FM. It is equivalent to burning pages of the Quran in Afghanistan!
None the less, take into account the percentage of Sandisk cards that are counterfeit, i have read estimates, on this site up to 60 %.
Then, personal experience-7 bad Sandisk cards versus 0 bad lexar!
Everyone to your own poison-enjoy!
