I have an old HP Pavilion dv2 laptop and was planning on upgrading the HD to a SSD. I currently have a Crucial M4 128gb SSD on my desktop, so I'm wondering if I should move the M4 to my laptop and invest in a higher end SSD for my desktop? Will I see any noticeable improvements with a more recent SSD? If not, I was thinking I would just go with a Kingston V300 60gb for my laptop. I would assume even a lower end SSD will be a huge upgrade over my old 5400RPM Toshiba drive.
