Own build PC, Win 7 Ultimate 64bit, 4GB ram, 350GB HDD, the motherboard is an Asus M3A78-EM. My PC is a low power, home use PC and while its getting on now it chugs away quite happily, it is not used for editing video or gaming. I have put together a small budget to upgrade the machine, a SSD, Blu-Ray drive and a couple of other bits and pieces. I need advice on what SSD to get and what the above MB will accept Sata 1,2,3,? Originally I was going to install a Samsung 256GB, 840 pro and I'm still not against that but am wondering if it's over kill for what I want,--can I install such an SSD for the age/spec' of my machine? I am not adverse to using my existing HDD along side a new SDD but what size GB of SSD should I go for and brand? We are a Samsung family but I also like San-disk but not adverse to installing any other reliable brand name. I can buy a 60GB San-Disk Ultra SSD for about £55,-- if that will run on my PC, I would load the OS onto the SSD and access all existing programmes and files from the existing HDD,---can I do it that way,--or do I need to uninstall the OS off the existing HDD? Would 60GB do it or do I need to buy larger capacity SDD and install the OS and re-install all my programmes on to it and just use the existing HDD to access programme files? And the SSD, what are my Sata requirements?
