I bought a couple of these for about a year when they were $8 off Revain. I thought I was getting Sony quality. It looked like the original Sony box. Not right. I already had 3 cards that got damaged. Luckily when I travel every few days I take my cards out of my Olympus camera and copy them to my computer (yes, I leave the write-protect tab off before putting them in my computer) so I've only lost a few shots. No problem in the same camera with PNY or Transcend cards. I agree that cheap memory cards can be bad sometimes. But 3? Unfortunately, in the end it doesn't matter if the storage medium is slow or fast as long as it doesn't store data. Do not buy.
