  • Common512gb!

    • I would pay 100 for a 512

    Blimey. Had no idea these larger capacity cards were getting so cheap! This will make a great upgrade from my 128gb, thanks for the deal.

    Hi, i have a nintendo switch and also a gopro, is this good for those?

    • +3

      Can confirm this works on my switch, no idea about gopro though

      • Am wondering the same thing if it's fast enough for the GoPro.

        • +3

          If you're hoping to use this for 4K recording or something with the newer GP's then you're going to run into problems. The write speed will be way too slow for it.

          If you're not recording in 4K then you're better off getting a quicker, smaller capacity card anyway since you won't need that much space & can then record 4k when needed (unless you're one that just continually records without ever copying data off it for a long time).

          • +1

            @Devil: Also to note is a lot of people report issues with 256gb+ microsd with GoPro.

            • @[Deactivated]: Agreed, I'm still on 64gb myself which holds 2hrs at 4k which I find plenty. I know that 128gb works fine too.

          • @Devil: @Devil that makes sense, I don't record much 4K cause my PC processor can't handle it at present. I'll hold off on this for the moment.

            • @balu: Do you mean your PC can't handle the editing? If so, which software do you use?

              Stick with a smaller size card if you're only recording in 1080p or lower. At 1080p, you'll get over 4 1/2hrs on a 64GB card which is a lot. If you're doing that much recording before copying video off (like on holidays or something), you're better off getting 2 x 64gb or something just in case you lose one or it goes faulty.

              Recommend something like a Sandisk Extreme v30 64gb card as a minimum. They're quite cheap and will record 4k if you ever want to step up in future.

    • Every Micro SD card deal someone asks about the Switch :) Surely the list of cards that don't work with the Switch is shorter…

      I just did a little bit more research, I seem to always have to refresh my memory when it comes to SD and Micro SD classifications as they can be confusing but here it goes.

      The Nintendo Switch only supports one type of SD bus speed, UHS-1 (Ultra High Speed 1). Bus speed is how fast the card can talk to the device. It does not support UHS-2 or UHS-3 so buying anything other than UHS-1 is a waste of money as the Switch will not be able to utilize the higher bus speeds.

      The next thing after sorting out the correct bus speed (UHS-1) is to get a Micro SD that has the fastest write speed. There are two speed ratings U1 and U3; U1 means the card must support writing at 10MB/s, U3 means 30mb/s. So you will want to pick up a U3 as Nintendo recommend cards with a read speed of 95mb/s which easily handles U3 speeds.

      TLDR: For Nintendo Switch you want to buy a Micro SD card that is UHS-1 bus speed, and U3 write speed to get the best from your console.

      EDIT So what this means is that this post is not the fastest Micro SD you can get for your switch as its U1, not U3.

        There is also the "Application Performance Class" (either A1 or A2). This rates random (non-sequential) read and write speeds. How important this is depends on what you're doing with the card. If you're running an EmuMMC from the card then it would be quite important, if you're just streaming game data from the card then it would be less so (but perhaps still worthwhile - I haven't seen any tests so I'm not sure the impact).

        The "Lexar High Performance 633x 512GB microSDXC" is UHS-1, U3, A2 and has come close to $100 according to an OzBargain search. Though personally I don't trust Lexar memory since the acquisition (I haven't done much research into the matter however).

        • That is still pretty impressive at nearly $100, I will need to check and see if there are any other microSDXC cards that can offer me 400+GB, UHS-1, U3 and A2 (which I think is an android certification for random read/write?) at around $100 I would probably go for it.

          I might try and find out how A1 or A2 certification affects Nintendo Switch usage. Hopefully there is something on the internet.

    Wow I remember paying over $50 for 64gb five years ago and thought that was plenty.

    • +2

      a year? thats like a life time in tech years hehehe

    • Bargain. Sony Memory sticks were $399 for 128MB if you go back far enough.

      • +1

        I have one of those 8Mb Sony memory sticks I dug up recently. And those 4Mb/8Mb save disks for the ps1/2 could hold everything we needed too!

      • Crazy how far it's come. Our first family PC had 40gb if my memory serves me correctly.

        • +1

          My 1st PC had a 20MB HDD as standard. :( I upgraded to the latest & greatest 40MB HDD that was released 1 month later for $200+. I think I still have 5MB MFM drive somewhere. lol

          • @nevermindnosey: My first PC booted off a 5.25” floppy. If the disk wasn’t in, it wouldn’t boot.

            • @[Deactivated]: Yep. I remember loading Impossible Mission on Commodore 64. First version took about 1 hour(well, 253 counter clicks) to load….under 64K. At least the loading music for Hyper Sports became pretty memorable.

                @[Deactivated]: Another visitor…. Stay a while, stay forever!!!

            • @[Deactivated]: Yep I remember the days of the floppy (360K?)boot but I didn't think it was worth all the the effort.

              I had a secondhand IBM XT with a super fast 6MHZ CPU & 5MB MFM HDD given to me when the ATs 1st appeared on the market & that sparked my interest in PCs.

              It seems we have advanced leaps & bounds since then.

              • @nevermindnosey: Most people couldn’t afford the XT (or any genuine IBM machine).

                Most of us used machines like the Amstrad PC1512 instead.

  • Struggling to fill my 256GB card with FLAC files. Great deal for 400GB BTW.

  • +3

    Bought one then cancelled as under the 1 star reviews people are saying they sold fakes in the past

    • It's an easy thing to test for once it arrives and you should have no issue getting your money back or asking for another to be sent.

    • You should only buy memory from seller Amazon. The reviews include marketplace sellers who are dodgy. Amazon proper is reliable.

      • So is this an Amazon proper supplier in this deal's case?

        • +1

          "Ships from and sold by Amazon US."
          This is sold by amazon. Otherwise it would say "sold by XXXX" with XXXX being the store/vendors name.

        • I'd test it anyway, I bought one some time ago (400GB) and it was a legit card. The reviews that were left I think was for the smaller variants if I remember correctly.

          If it's fulfilled by Amazon it'd be easy to get a refund or replacement if it turns out to be fake.

  • Seems like it was only the 256 GB batch from the reviews.

  • +1

    If the product is sold/shipped by Amazon themselves, it's unlikely to be a fake. Some of the third party sellers on Amazon may be selling fakes, unfortunately the reviews are specific to the product listing, not which specific seller they were bought from.

    The negative reviews are most likely from a purchase from a third party seller.

  • Thanks!
    Picked up one for my wife's new phone.

        You misspelt the word 'of'

  • Anybody know more about speed of micro SD cards? Would want to get a high capacity one with maximum speed.

    • These (the Sandisk Ultra range) are slow. The Extreme range (or Samsung EVOs) are now considered "regular" speed.

      • This card is definitely not slow. I have one and with a USB 3.0 card reader I'm getting around 90 MB/s read and 68 MB/s write speeds.

      • Are Samsung EVO+ faster than this? I thought they were on same level

        • The original EVO+ range were same speed as Ultra, then they changed the name to EVO Plus and increased the speed.

    • For a phone this would be fine, up to 100MB/s (U1).
      If you want faster this may serve you well https://www.amazon.com.au/Sandisk-SDSQXA1-128G-GN6MA-Extreme… up to 160MB/s (U3)

      • U1 is minimum 10MB/s writes.

        • Yes and U3 and V30 is minimum 30MB/s writes. While the max speeds can very between cards the A2 classification on the Sandisk Extreme might mean better performance on a phone as it gauntness faster random read/write?

  • Nice! Just when my "Silicon Power" micro sd is crapping out on itself. Definitely never buying an off brand micro sd card anymore.

  • I bought that for $72 yesterday from Amazon AU. Must have sold out.

  • Many reviews saying these are fake?

  • Any genuine 1TB sales?

    • You are wanting to purchase a 1TB Micro SD Card? Why?

    • Filled the 400g one.

  • People actually stored that much shits on their phone or tablet these days? This is like desktop type storage ffs..what am I missing out on my phones

    • Memory cards are not only for phones or tablets, a lot of new laptops have micro SD card slot, Nintendo switch is another one, also cameras…

  • What's the "cashback" we're supposed to remember ?
