Hi everybody :

I have a Gigabyte GA-Z77-DS3H motherboard.
Also, have a WD5003ABYX (500Gb Western Digital Drive....and an LG DVD drive (Model : CH12LS28). The WD is the drive with the OS.
I'm thinking about purchasing an mSATA drive. The results of the research that I've done give me two possibilities. One.....an mSATA drive will ONLY work as a cache. Two.....it can be used as a second drive. The two other options I'm considering are : (1) Buying as SSD as a second drive, (2) Buying another WD 500Gb Hard Drive. I'm not sure which way I'm going to go. Advice ?
