F2FS was designed for raw nand flash drives, not managed flash as an SSD is. It is not tolerant of power failures (so fine on a phone or tablet that has battery and knows the power state, not so fine on a generic PC). On a drive with built in management of the flash, as any SSD used in a PC has, ext4 is a much better choice than F2FS with better performance and better reliability. So Debian and Ubuntu have sensibly not bothered to offer the user the choice to use a filesystem that would be a terrible idea to use in general. F2FS works just fine when used in the right place, which is on raw flash chips on devices with safe power supply. It does not work well in other settings. So what you read is either wrong, or you didn't understand the conditions that were listed as required to make it reliable. -- Len Sorensen
