April 1, 20251 yr I saw someone using ZFS on their Netgate hardware and their eMMC fails in a year. Would BTRFS significantly shorten lifespan of eMMC/SD card, like ZFS does? Edited April 1, 20251 yr by abceleung
April 13, 20251 yr armbian already move a lot of directories to tmpfs to reduce the amount of writes. a misconfigured system can of course reduce the lifespan of flash memory but that will be the case regardless of filesystem. there are ways to mitigate write amplification, for example. you will need to monitor the write activity on your memory. don't fill it up completely. iostat or nmon will help you see how often and how much is written to disk.
April 13, 20251 yr i'm writing this from an aarch64 chromebook running mainline linux with 32gb of emmc (usually 90+ % full) which i'm using as daily driver for over two years now with firefox having many dozens of active tabs open all the time, so that its usually about 1gb into swap with its 4gb of ram (despite using zswap memory/swap compression) and so far it is running fine without problems und due to the btrfs internal checksumming on read those would be visible immediately ... same applies to a few small servers with a similar setup running from a1 rated sd cards, all fine as well ... this is not armbian, but btrfs (which should be the same everywhere) - maybe formatting with "-m single" and mounting with "ssd" option might be a good idea (at least this is what i use on above mentioned systems).
