Not just performance. Reliability and data loss are also bad. All of these adapters do raid-0, which means any one card failure (very common, I have seen it a lot in my personal devices) will damage the volume.

As I have a lot of odd SD cards unused in drawers I would be more interested in these adapters if they exposed every card as its own drive so I could do ZFS, or if they did "real" raid.
