The current state is mostly that people put unaligned partitions on their SD card, stick an ext3 fs on a partition and watch performance suck while destroying their cards.

Agreed :-)

There has been a study by Thomas Gleixner on what CF cards do, which basically showed that they all use the same broken algorithm. It may be interesting to do the same for SD cards. We could also ask the Samsung people in Linaro to find out more technical details than are currently known publically about Samsung SD cards.

Ok; that sounds good, will check out with the TSC what exact SD work they are expecting and then we can see whether there's an FS part to it, but it sounds like useful research in any case
