Should you resize root partition on flash?

  • So the flash memory will die eventually to writes.

    There is an option to extend the root partition to the whole flash card size. Will this help to redistribute writes? Or otherwise?


    Thanks for help!

    There is the flashmemory plugin which is significantly reducing the writes to the SD card.


    As far as I know it does not matter how large the partition is. The controller of the SD card will level the writes to the complete available flash.

    Get a mirror?


    Most likely you installed software in a way that means that flash is being used for storage. For instance docker app data with metadata databases for media servers.


    You should create a share on the hard drive and use that instead.


    There should be no need to resize partitions on the SD card. If you feel a need, then you are doing something very wrong. However the worst(?) that can happen, I assume, is only that the card fail prematurely and you may lose all data on the card. You can buy a new card, right?


    Even if you only have a 8 GB partition on a 64-128GB card, that is perfectly fine. Leave the unpartitioned parts unpartitioned. Wear leveling will make use of the whole card.

  • Honest suggestion after having usb key or SD cards dieing: install OMV on the cheapest SSD you can find (64/128GB) and stop worring about it.

    That’s fine if you are using an AMD-64 machine and don’t mind sacrificing a SATA port.

    I have an AMD-64 machine and I didn't sacrifice a SATA port. I put the OMV 2.5in 16GB SSD into an external USB case and plugged into a USB port.
