This isn't a kernel question, it's a Linux 101 question. Using /tmp as a staging area may or may not work - it depends what you call "huge", and what you call "frequently", and how often you need to write to the SD card. I suspect my definition of "huge" and yours differ (mine includes users who have petabytes of data and want to see 3 gigabyte/second throughput). Bottom line, part 1: SD cards are relatively slow. If you need to log data on average faster than the SD can write, you're basically screwed (unless you introduce something that does compression or filtering to get the bandwidth below SD speeds). Bottom line, part 2: We can't tell you *how* to do it, because it's going to depend on whatever is generating the "huge data" and your options for interfacing/modifying it.
