Finally I bought an SSD and mounted it on my laptop. I have a 5 year laptop with an i3 process (old generation), 2 years ago I have extended the 4gb and now I have 8gb (more it does not support) Now not wanting to buy a new laptop, I thought of a solution to speed it up (too many sw slow it down) and so I decided to buy SSD. Finally Tuesday I bought my SSD .... first impressions? In fact, the start is incredible, in a few seconds it is operational, before it also required 5/10 minutes to start completely. For installations, I have speeded up but not too much, because much depends on the CD player and the machine as a whole. Now I can keep going another 2 years. I had Windows 8.1 64bit, I tried to passae to windows 10 64bit, but crashed continuously, but I do not have a good relationship with W10. Also other installations that I have done to my friends check the blue screen continuously. So I switched to Winwdow 7 32bit (I do not own the 64bit version) and it's working fine for now. My favorites are Win7 and WinXp. I had a 500gb HD with only 100Gb free. Now I have reinstalled everything and copied my personal archive. Now I have a 500Gb SSD with 350gb free ... Probably doing a clean installation I saved a lot of space.
