Other commenters in this thread have mentioned netbooting their Pis to avoid that exact issue. A typical USB flash device won't be any more reliable than an SD card, though it might be better cooled.
- ComputerGuru 6y ago> A typical USB flash device won't be any more reliable than an SD card, though it might be better cooled. That’s not strictly true, as the USB storage controller abstracts away the NAND and can manage wear leveling and free blocks. There are also more “enterprise class” USB sticks than SD cards, and the USB3 interface to USB drives is much faster than pretty much any SD card interface. Best SD cards and best USB drives are Sandisk Extreme Pro, built entirely differently from their other lines. While Samsung Evo SSDs are top-of-the-line in each budget class, stay far away from their Evo SD cards which shamelessly borrow off the SSD reputation then drive it to the ground. They all tend to go read-only after undergoing “extended” writes. Suggestion: if you’re using Linux, stay away from the ext family of file systems when using SD cards. Use nilfs or f2fs, and XFS if you absolutely must use a journaled fs.
- GekkePrutser 6y agoCan confirm the read only. Indeed had it with 2 cards now. It's really annoying because the OS still caches writes in RAM so you only find out when you reboot and all your changes are lost. Still, not quite as bad as completely corrupting I suppose...
