ic. oh man

one more thg, can i fix a msata ssd into msian set which does not originally come with ssd ?
some ppl claim that theres no msata slot on certain models.
You can't fit a msata HDD/SDD in either of Y410P or Y510P.
Y410P has a NGFF (or also called M2) port as claimed by the lenovo resellers. You can put the suitable 42mm NGFF SSD in it. However it is still a new factor and not many 42mm NGFF SSD are out there in market as of now. They will become more and more popular in future I guess, as their speed is better than sata.
Y510P do not have any additional port. You can only put your SSD in the sata slot that the original HDD is using, and put the HDD in the ultrabay (requires a caddy bay, replacing the optical dvd drive).
In short, for local set
Y410P : 1 SATA (occupied with original HDD) + 1 NGFF
Y510P : 1 SATA (occupied with original HDD)
Correct me if I'm wrong as these are the info found from web and resellers and not self checking.
