Bests & Worsts Reviews from Amazon

Engineer here. So I have to rate this as a 4 star due to it lying to us a little. You are likely buying this because you have a mirrorless camera and need ultra fast recording speeds of 95 MB/s I just ran F3 a testing utility. We got Average writing speed: 65.25 MB/s Cool, but the package says Up To 95 MB/s. Granted that is likely the peek max, not the average, but we the users want to know if it will actually work for 4k video. That said, it does go above and beyond its "technical" classification. (those useless symbols that are greek to even most engineers on the card) The SD XC, with a roman numeral one, or "I" means its rated for 12.5-104mb. Which is pretty useless. The clas U3 on the chip means it has a Minimum of 30 MB/s, which is equal to a v30 for video. TLDR, the fine print it is running to spec but clearly deceptive in it's perceived performance by its packaging.. But maybe look for a class 2 card, or a Video class of 60 or above. If you don't have a mirrorless and you aren't doing 4k video, then buy a cheaper card than this.
