I know that an 500 gig ssd would be all I need because I have a 500 gig HDD, plus a 1TB external hard drive that I use for backups and storing things that I don't want on my laptop like power bills etc.
Yes mine is a 64 bit, wouldn't go with a 32 bit and here they only sell 64 bit PC's as I have not seen an 32bit for ages that is brand new. I do know that having an 8 gig will help, cause i do a lot on my laptop, and also I have even turned off the page file, as my computers always run faster without it, and I have been doing that since my windows 7 PC, That way my computer is relying on my ram only, and that is why I am upgrading it in 2 weeks time to another ADATA 8 Gig DDR3L 1600MHz.
I mean fitting it into the part where the HDD is. I don't mind reinstalling everything from scratch cause I have all the software on my external of what I am keeping and all my backups. I do my back ups every month to every 2 weeks.
What about using things like crap cleaner and kaspersky? Can I still use these as well, it may sound silly, but as I stated before I have not used an SSD, but the only reason I want to change to one cause its a speed improvement.
