Currently my system uses 500 GB Western Digital SATA HDD. Only 50 GBs used, along with installation of Windows 7. I dont want any more memory than this. I have external HDD for that. But in future i am thinking about adding a 120GB SSD. This is only to install windows 7 and some important programs. As far as i know that SSDs have a high failure rate as well as extremely short short life. Is it true? if not, is there is compatibility issue between the motherboard and installing SSD on it. I own Gigabyte GA-Z68X-UD3-B3.
