      @ankonaskiff17 If I have the big USB drive hard drive or SSD dive I mentioned earlier in this convo, can I create multiple partitions to mimic multiple drives, a small partition to boot Pi from but subsequently the different partitions would represent say c;\ , d;\ etc and just store files folders to different (I guess these would be virtual drives) as I desire? Would just be either the SSD or platter which I’m still debating.
      SD Card slot underneath would just be empty

        @ankonaskiff17 yes, you can create multiple partitions.

        Linux doesn’t use drive letters, it’s all one big naming space

        / is the root

        and you can mount other partitions into that space anywhere you want.

        you use the file /etc/fstab

        to configure where to mount volumes

        there are graphical tools for creating the partitions. gparted is the one I use most often

        if you use gparted to look. at your SD card I think there are 2 partitions

          @sdetweil So, if you had a 500 GB HDD or a 240 GB SSD which would you use?
          Is there some industry standard as far as creating partitions? Size, Drive letter, etc?

          Now, I don’t have any expectation that I would get anywhere remotely near the capacity of either style storage device with meaningful data in form of files I want to save so sort of abstract question here.

          The below is based on all experience being from Windows 3.1—>Windows 11
          ZERO Linux until discovery of MM.
          In a dusty corner of my brain I seem to recall something about when a computer is up and running it uses a portion of its storage media to put a running program on. Say you are running a complex Excel spreadsheet, some of that will be in RAM and some will be a chunk of (historically) HDD space. If I’m way screwed up just say “that ain’t how it works” and I’m fine with that.
          BUT, if an SSD only writes once to each block of memory, I could see how that could chew up an SSD’s storage capacity over time

            @ankonaskiff17 you’ve got it ok.

            I have 15000 pics I’ve taken, consuming 2 TB of disk space

            for me, fewer partitions is better, but on my windows boot I have 18 drive letters…
            I have two external drives, one 5tb, one 8tb…

            but, all drives die…

              @sdetweil Photography must be a hobby. Smart phone pictures wouldn’t take up that kind of space.

                @ankonaskiff17 and @sdetweil I have a slightly different question. For MicroSD cards, would you recommend the standard C10 or U3 or A2 MicroSD cards? C10 has minimum of 10mb/s, U3 30mb/s and A2 with a higher rating and then to V90 with a much higher rating of around 170mb/s max. Which would run MM best in your opinion provided RaspberyPi can handle the card type?

                    @mumblebaj Not qualified to answer but will piggyback a comment about an issue that I got into in a year or so back as it relates to these microsd cards.

                    About a year ago I bought a kit from Raspberry Shake and they wanted to sell me a microSD Card that had their logo on it but amounted to an industrial grade microSD Card. I got curious about the cards because they can be significantly higher priced than a consumer grade card. I came away from that dive down the rabbit hole that they undergo a much more harsh testing/qualification regime than what you would find at your local electronics store.
                    They are oriented towards industrial applications that might see significant vibration and/or temperature extremes.

                    This is what I bought and for where I have that earthquake detector it is probably extreme overkill but better safe than sorry.

                    If you are curious about things Raspberry Pi’s get used for every hexagon on the below picture represents a Pi being used as an earthquake detector.

                      @sdetweil said in SSD vs Old School Spinning Platter:

                      @ankonaskiff17 so. ssd technology is write once memory. once that bit is written, it cannot be written again.

                      Uh, no. The cells that contain the bits do wear out over time, calculated in Total Bytes Written, but they are re-writeable. Writing and rewriting those bits causes wear. And the SSD has some overhead to let you maintain the listed capacity over time. But it is a read/write technology.

                      There are some write-once SSDs on the market, but you have to specifically purchase them. The few that I found are Windows-only.
