  • Is this good value? I need one for my S10+ and I don't have a great deal of knowledge about them. Any help would be appreciated!

        Sold by Shopping Square.

        I wouldn't buy from them given their eBay score and the consistent nature of the negative feedback they get.

          They're super slow to post out and charge you $10 to receive the cards in a standard DL size envelope with no padding that probably cost them $1

        The Samsung Pro cards are more comparable with this Micro SD card.

  • I'm about to get the new Go Pro 8 Black, is this still the fastest writing micro SD card you can get?

    • Make sure to check if its eligible to work with Gopro or not. They have their compatibility list, check in that!

    Perfect card for bunnings drones.

  • Anyone know if these are fine in Blackvue dashcams?

      Do you honestly believe your dashcam will write to the card at more than 90 megabytes per second? Broadcast quality doesn't even come close that :)

        Speed isn't the issue, it's more about the amount or writes, heat, durability. I've had other brand micro SDs work for 6 months without issue only to fail later. The last failed one became 128gb storage extention for my phone, I don't need another one.

  • I'd love to get one but it sounds too good to be true. The seller's got 'only' 2275 ratings though, guess I'll take the gamble.

    The read speed is almost a lie.
    This card has a UHS-I bus, which has a maximum transfer speed of 104MBytes/second. This is the maximum speed you'll get on any standard devices.

    To achieve 170MBytes/second, that only works with a particular Sandisk card reader, which clocks the bus faster than UHS-I does, and there is a proprietary protocol so that card reader doesn't try that speed with "normal" UHS-I cards. Other devices and card readers, and most Sandisk card readers, can't do faster than 104MBytes/second.

    Also, the write speed is fishy. V30 means the card has a sequential write speed of 30 to 59 MBytes/second, if it can achieve higher it should be rated V60 or V90.

    Wikipedia has all the definitions of the speed ratings, see the "Speed" section:

    Just for anyone that's interested in purchasing this to use in a camera; below is that cards stats when used in the Panasonic G9:

    SD Memory Cards USB 3.0 Read USB 3.0 Write Panasonic G9

    Sandisk Extreme Pro U3 98.6 MB/s 90.8 MB/s 38.03 MB/s

    This is apparently the third best UHS-I card (for the Panasonic G9), before jumping up to UHS-II. I'm not ready to shell out the big bucks for UHS-II, so I'll be picking up two of these. Like someone else said, the Samsung Evo Plus is better value, but I wouldn't buy from Shopping Square
