I have an 8 yr old DELL Studio 15 laptop which works fine. I use it primarily for gaming along with some light use like learning new stuff like Python & watching movies. Lately, it had become terribly slow. After several tests, I determined that the hard drive (WD 7200 rpm 320GB SATA) was pulling the performance down of an otherwise brilliant laptop. Currently available laptops in the budget range don't have much more to offer than what this one already has & the latest gaming laptops are way too expensive. So I swapped out the old HDD with this one & reinstalled Windows 10 and other stuff that I use normally. Now it feels like the laptop is on steroids!!!
