win 8 on sata

Hi I am new at this so forgive me if this has been answered before but I could not find it, I have installed windows 8 on a hdd on my computer, it runs really well no problems so far, but I have seen a deal for a 1tb sata hdd. my question is If I buy the sata hdd will I be able to reinstall windows 8 onto this drive and have that as my main drive. thanks for any help

Why not buy, & use just for DATA, no need to reinstall.
