    Gonna wait for that 1tb card to come down… Must be patient!

    • The true OzB way

      • 1tb is available? Which brand ?
        Compatible with note 9 ? 🤔

        • +1

          Sandisk and one other brand

          Yes, should work with 99% of devices made in the last few years

  • +6

    Wouldn't be bad for the Switch.

    Blows my mind still, such tiny cards holding the amounts of memory they can now.

    • +12

      What's even more crazy is when you think that card contains the memory, but it also contains a controller, the packaging, interface (pins) etc.

      Or think of it this way: spotify has a catalogue of about 30 million songs. If we approximate that each song could be stored as an mp3 averaging 5MB, then it means that the entire spotify music catalogue could be stored in (30,000,000 x 5 / 400,000) 375 of these cards. You could fit all those cards into three redhead match boxes.

        O Man … Spotify is operating from a matchbox ? 🤔🤔🤔

        • +2

          No the memory is. But it's attached to a raspberry pi so still pretty small.

        • +1

          Imagine how much data could be stored in Matchbox 20.

      • This guy maths.

    • When those cards get damaged, people even sand the package off to expose the die, then solder tiny wires to the memory directly pass the controller then read and recover the files, blows your mind :)

  • is this one ideal for SWITCH?

    • +1

      Sure. Switch doesn't really benefit from higher speeds.

    • The write speeds are poor but it shouldn't matter for the Switch.

    • Been using one in my Switch for a while now and works great. Writing to it is a bit slow though.

    I bought this a few weeks ago when it was around the mid $70 mark (from memory). Seems to be chugging away nicely in my V30+

    I feel the Samsung EVO 512Gb at $130 is still too pricy for the extra 100gb or so.

    If you can afford the extra $$$ for the EVO, you'll get with faster write performance. While U1/U3 is a minimum speed rating (which both cards exceed) my sony camera complains if I try to use a U1 card for recording 4k video although the sd card is more than capable in the write speed department.

      (from memory)

      I see what you did there.

      • I was just thinking the same thing, giggling to myself.

  • Wonder if this is worth using for storing movies on the go. I'm using a portable non SSD at the moment.

  • +1

    Are these good for dashcams? Assuming the dashcam is compatible with larger card sizes.
    Or are these not good for constant rewriting?

    • They're aren't designed for a high number or writes, but I guess it depends how concerned you are. I assume your dash camera would throw an error if it could no longer write to the card, so you'd know to replace it when that happens. As long as you're proactive then it would be cheaper than buying one designed for high rewrites.

      • Do you mean high number of writes in a short time period? If not, what sort of write numbers are we talking? Eg: For Nintendo Switch, where you will 'write' when saving progress etc.

    • Hi @Unco,

      I use these for my dashcams and they've worked a treat!
      Can withstand constant rewriting!
      Been using for past 3 months!

      • Only 3 months? I've had the same non-endurance rated samsung evo card in my dash cam for over a year.

        • mine died at around 18 months. pretty good run. now im using a high endurance card, will be interesting to see how that goes. Also im curious with a higher capacity, wouldn't it take longer to screw up? due to taking longer to fill up, should mean less rewrites overall.. maybe im wrong.

    What's the deal with the Amazon reviews claiming they're fake?

    • +1

      You have to understand consumer behaviour. Amazon hosts for other retailers too, which may stock fake products. The consumer then complains about the retailer/product, but Amazon's product review is for the actual product itself, and is not indicative of the trustworthiness of the retailer (and, by extension, their products), if you get what I mean. It's like if I went to the Sandisk website and wrote a review about how dodgy my received SD card from Ebay was, when really, I should've complained to the seller.

    • +1

      Amazon mixes reviews of products among sellers so possibly a 3rd party seller sold a fake at some point, as long as the seller is marked as from amazon themselves it should be fine. But also possible that some buyers are idiots and got real ones

    • Amazon hosts a lot of sellers that sell fakes, and Amazon is really slow in removing them, but once they do the only place users can post a review is in another listing. Be extremely careful with memory cards and earphones especially. If it says "Ships from and sold by Amazon" then it's likely genuine, but do not trust the "by xxxxx" where xxxxx could be Sandisk or Sennheiser etc.

  • Write speed between 10 and 50MB/s (dependent on file size) according to reviews.

    Seems about right, as my own testing with a usb 3 card reader - albeit with a 128gb version - averaged about 17MB/s while transferring large MKV's via Windows 10.

  • Has anyone had experience with this specific card in a GoPro? I've got a Hero5 and need to buy a replacement but GoPro's seem to work better with the ones recommended on their website (not necessarily a consumer review). Any advice would be appreciated.

  • Down to $79.28

      Thanks updated.

  • Damn, it really has come to this!! :O :D

  • I haven't used a third of my 200GB card, I'll buy one when I have used 80% of my 200GB card

  • Any cheap A2 spec card 200GB and above?

  • Is this compatible with the Eufy cam?

  • Usually dispatched within 1 to 2 months. Does this mean that it is now on back order?

    There are others on Amazon for $83 (which this was originally showing) and a few $$ for postage make them about $90 each. Still a saving on the $120/130 locally.
