    Is this good for Switch Oled? I just got one and was considering doing the digital route for my main games.

      Yes,enough for switch

    Does anyone know if an old RPI B+ will take this?

      I’ve not tested, larger than 64GB on a PI 1… I can’t see why it wouldn’t.
      I assume this is the 1.1 revision since the original Pi of which I have one took full sized SD

      • peuwayaqdq on 08/11/2021 - 19:15

        Yeah it takes full sized SD card

      The PI will eventually destroy the sd card if your using it for the OS. Stick to smaller and less expensive sizes, or save the cash for a ssd.

      • peuwayaqdq on 08/11/2021 - 19:15

        thanks for the info.

        The PI will eventually destroy the sd card if your using it for the OS.

        It's trivially easy to prevent the RPi from writing to the OS partition, the ability to make the OS partition read-only has been around for more than a year. Here's a forum post giving the basics: https://forums.raspberrypi.com/viewtopic.php?t=285958

        However, with such a large card, you're obviously intending to use it for more than just the OS files. So partition it into a small boot partition, which will become a read-only OS partition, and partition the remainder of the card as a second partition, which you can format as a read-write data drive. As each partition has its own file allocation table and directory structure, writing to the second partition won't wear out anything in the first partition.

        For the data drive, if you want protection against accidental power outages that may cause corruption if the power outage happens while a file is open or being written, then format the data partition with a journaling file system, like EXT4 or JFS or XFS. Note that this may make it impossible to stick the card into a windows machine and read the data, as Windows doesn't have drivers for these filesystems, although there are ways to read EXT4 on a Windows PC.

        • peuwayaqdq on 08/11/2021 - 21:47

          So was the issue with the OS will destroy the SD card is for the frequent write on the partition? I am just trying to understand why making the partition used for the OS read-only will prevent that from happening. Thanks.

          • Russ on 08/11/2021 - 22:44

            @peuwayaqdq: Correct. Every time something OS-related happens, the OS will usually write it to a log file. Just booted? Write multiple messages to the log file. Plug in a USB? Write to log file. Wifi connects? Write to log file, and so on.

            But because of the way flash memory in SD cards works, you can't just add a few bytes to a file. The minimum size size data block that can be written is 512bytes, so even if your log message is only 20 bytes, it has to copy the last bit of the log, add the 20-byte log message, write it back to a different memory block in the SD card, erase the "old" block that was just copied, and then update the file system to say the "old" memory block is now available, the "new" block is in use, and link the "new" memory block to all the other blocks that make up the log file.

            So just one trivial event results in multiple writes to the card. If you want to see some of the messages, open up a command prompt, and type the command "dmesg" (without quotes) and hit the enter key. This shows just some of the things the OS records.

            The thing about logs is that they are usually only useful when something goes wrong, and you want to figure out what went wrong. And there are loads of things that could go wrong, so the OS records everything, in case it's useful. 99% of computer users won't need to look at logs.

            With the read-only technique I listed above, a file system is set up in the RPI's RAM, and the logs are stored there. So you can still read them if you want to, but when power is turned off, they're gone. If you have a fault that shuts down the RPi, then you won't be able to read the logs to see why the RPi shut down - in this case, turn off the read-only settings, and the logs will be stored onto the SD card again, so you can read them after the next boot-up.

            • peuwayaqdq on 09/11/2021 - 08:25

              @Russ: Hi Russ, thank you for your explanation. That makes sense. I wonder if making the system writes log to RAM will make it faster or slower because it needs to constantly swapping.

                @peuwayaqdq:

                making the system writes log to RAM will make it faster or slower

                Writes to RAM are significantly faster than writes to SD card, even with the way the above technique redirects the writing of logs to the RAM file system.

          • peuwayaqdq on 09/11/2021 - 08:27

            @peuwayaqdq: Bought one :-). Thanks OP

        • peuwayaqdq on 13/11/2021 - 23:20

          Hi @Russ, can I get some help? I have received my card and use RaspberryPi Imager to put the RaspberryPi OS on my SD card. However, it seems that RPI use the whole capacity in its root partition. How do I put RaspberryPi OS on the card without using the whole SD card? Obviously I can't partition the card prior to imaging the card. Any help would be appreciated. Thank you.

          • peuwayaqdq on 14/11/2021 - 21:31

            @peuwayaqdq: I have been able to resize the rootfs partition using Gparted on a Linux computer. I have also run raspi-config and enable Overlay Filesystem and made the system read only. However, I am not sure which partition/folder that has been made read-only. Log seems to be writable. Please help.

            • peuwayaqdq on 15/11/2021 - 13:12

              @peuwayaqdq: Nevermind … figured it out … I still can write to home dir but it is writing to RAM and will be gone when I reboot.

              • Russ on 19/11/2021 - 01:47

                @peuwayaqdq: Apologies for my late reply, I haven't logged in for a week or so, and didn't see your query.

                You did do it the correct way, install then resize the partition, and then make a second partition in the remaining space.

                There is a faster way, you can set up the partitions first with Gparted, then install into the first partition. But it has been a number of years since my last RPi install, possibly the format of the install image has changed and this method won't work without some work-arounds.

                  @Russ: No worries 🙂

                  Yeah I think both RPI imager and BalenaEtcher will format the card and create single partition.

      No you’d probably want the extreme for faster write speeds and handling. At least if your drone has decent resolution

      I've been using the Sandisk branded ones for my phones and everything else. They've been the most reliable and have yet to fail. I've bought the Kogan ones and they always corrupted after a few years.

    Are these good for dash cams?

    • Kangal on 08/11/2021 - 20:42
      +4

      Yes and No.
      Generally these work well for dash cams…. generally.

      Australian heat is not kind to dash cams or microSD cards. The Endurance line of microSD cards is preferred, but they have a premium cost on them. Not to mention, if you have something like Surveillance Mode running (24/7) where it records and deletes constantly, then these cards sometimes cannot keep up and have one block that gets corrupted. When that happens it is extremely frustrating. Not only do you lose the footage, but end up with a lousy paper-weight. I've seen people reformat cards (eg 512GB to 2x 256GB), and use the working drive to try to claim functionality back, but it requires special software/hardware.
