Excerpt: Bought this SanDisk Ultra 64 GB microSD card to use in a GoPro Hero3. The card stopped working, or broke, in only 2 months and only after a couple times of use. While I was using the GoPro camera, suddenly the camera says "NO SD." I removed and replaced the card, powered down and powered up, everything, and still "NO SD." As a test, I put the SD card, using its regular-size adapter, in a digital camera. The camera would not work.
Summary: Out $20 for overnight shipping so it would be here in time to use with the new phone. Out $10+ on shipping to return it. This is my last SanDisk product and my last order from NewEgg. I'm out $30 and still don't have a memory card.
Cons: Defective on receipt. Would not mount in new Galaxy S5, took the phone to an AT&T repair center and they confirmed it was a problem with the card. Tried card in PC in the supplied adapter and it was inaccessible.
Excerpt: Card was working ok for nearly a month, then I started noticing curruption, so I put it in my pc to back up files and died somewhere in the copy proccess lucklily I got most of my importaint data off, now the card only reports 32mb in fdisk (linux, android), its completely un readable in windows no format dialog or anything and not even showing in Computer Management.
Pros: Large Capacity, Warranty Hopefully
Cons: Died 1 Month In, Slow - 8-9 Mbs Write, Unreliable Performance, Writes/reads slow
