Redis is quite fast on the Pi3, completely another story compared to the original Pi. With AOF enabled and fsync policy every second, without using pipelining it does 28k ops/sec. With pipelining it reaches 80k easily. Not bad for a hardware that is quite cheap and limited. About the problems with the SD card, in the specific case of Redis there are mitigations if it is possible to give up on durability. One could use snapshotting and configure a delay that will not trash the SD too much. I think PostgreSQL does a lot of random access in the on-disk btree, but other systems using some log structured storage in append only should create less problems in theory.
