I had some performance issues using ssd on my laptops a while back. At 
the time I couldn't find much out about the various merits of different 
filesystems and block sizes.
I recently searched again and found this document :

Looking thought charts ( I wish there was a podcast), it looks like a 
4kb block size is best, and nilfs performance best as the filesystem.

here's an interesting thread on using nilfs on ssd

Is nilfs availble for openmoko ?
