Mmm....it seems your BIOS to windows startup screen beats mine by 2 secs! Nice - but, you have something amiss in Windows, where I'm around 5-6 secs ahead of you - please bear in mind this is on my Zotac with XP SP3, full, standard version.
My Commell LS-373 does the same on W7, around 23 seconds to stable desktop - that's pretty quick through the bios, maybe 4-6 seconds on the Zotac - and the LS-372 is again 1-2sec quicker than my LS-373 - I had the LS-372 before.
Your SSD is pretty good, and for this application, that is an excellent choice - don't worry about the writes to much, in carputers, it's the reads that we use more often.
Anyway, have a looky at these W7 tweaks, and note especially ssd drive settings, as well as page file.
My pagefile is on the SSD, best place for it to be acording to the author.
Just do those applicable changes, and retest?
Keep us posted!
