Cool on paper but SD cards have abysmal write endurance, as any Raspberry Pi user will attest to.
Unless you trust the entire software stack to keep writes to a minimum I wouldn't trust the SD card to last.
- Aachen 3y agoI had this issue, presumably because I ran a Debian userspace below Android with a file on the sdcard as filesystem. Every ~3 years, the sdcard would just drop dead. (Other people seemed to upgrade faster than every 3y or don't use sdcards at all, so idk if it was just me.) It hasn't happened anymore recently, and I feel like there's more awareness/support for this type of usage pattern with the higher-end sdcards that are somewhat recent (like, introduced in the last ~8 years, so after the lifespan of an old cheap sdcard, I'm still on my first new-style one and I'm not yet sure it's not randomness that keeps it alive)
- jsheard 3y agoIf you must use an SD card then there are industrial-grade ones which use pSLC NAND and are meant to endure a ton of abuse, but they're very expensive compared to an equivalent amount of reliable eMMC/USB/NVMe storage. IME commodity SD cards are still a crapshoot.
- Aachen 3y agoSo far, one of these sdcards that claim to be optimised for applications accessing random files (such as on a Pi) works fine in my phone
- nonrandomstring 3y agoNot so bad, SD cards can be robust. It depends on the file-system and how much work the controller does to catch errors, mark bad cells, etc. I have a few portable handy recorders, a Zoom, a Tascam and a Sound Devices, and all of them handle the same SD cards for years, rarely complaining about format errors or losing files.
