I've read a bit about it and there is conflicting info out there. I once read that 512 is the sweet spot but another site showed read write performance graphs up to about 4000. The graphs indicated that you would get a gain up to about 3000 (+/-). I typically run mine at 512 with row scheduler. Row was created specifically for mobile phones and works really well for me. My best suggestion is to try them all for a few hours and see what settings work best for your usage. Hope that helps.
