I have a Dell Studio 15, bought in 2009. It's still working OK but off late, Windows has given couple of Disk Read/Write errors. Before it conks out, I want to upgrade the HDD. Currently its running the Samsung 320GB 5400rpm drive that came in it. Now I have a few queries: Can I put in a SSD ? Will it be thermally similar to a normal HDD or more/less efficient? If SSD isn't a viable option then can you list out a decent 1TB or more, 7200rpm HDD My laptop doubles up as WiFi access point and download machine thus need a reliable drive. Are SSHD any good? Have seen mixed views about it online?
