Excerpt: Did not notice any spectacular speed. I put this card into a PJ650 Sony Camera and when I placed the camera on the highest possible quality setting, the recording came out with choppy audio. Clear, literal in and out cuts. I placed this card into my AFT Pro-55u card reader and got 20MB/S upload speeds. I get the same thing with el cheapo cards. Eh, worth the money? Maybe in some way... but I didn't notice it.
Excerpt: I just got back from a trip to Disney. All my video is on this one card. (hours of stuff). The video quality is great. Just leave it in the camera and you don't have to keep track of several cards, just one.
Excerpt: I made the mistake of purchasing SDHC cards first. I then realized I couldn't record in the XAVC S Codec from the Sony a7s. Needless to say I ordered a couple of these and voila. No issues whatsoever.
Excerpt: I purchased this for my Sony A7M2 as it has a great price and reputable name behind it. So far it's proven to be fast enough for photos and video. I haven't had it long enough to judge error rate and durability.
