In beginning to research 2016 Laptop reviews for possible replacement of my laptop I ran across something, tried it, and the results are incredible. As we know, PCs & Laptops normally have Hard Drives in them that are motor driven spinning disks...and in spite of continuous housekeeping on their contents, the mechanical Hard Drives gradually slow down over time. Five years ago I bought what was a maxed out, top of the line Lenovo Thinkpad T510 laptop and it had gradually gotten slower and slower this past year or so. However, the current crop of Solid State Drives have no such mechanical issues and in addition, current technology makes them blindingly fast. Decided to try one, replaced the 500GB Hard Drive in my laptop with a 500GB SSD (Solid State Drive). Used to take 4 minutes to completely boot up and bring up everything I had set to open...now it takes 45 seconds !! And opening / closing applications, processing photos, etc, the screens basically just blink. Huge ROI for $150 compared to dropping $1800 for a new top of the line laptop...my current laptop may well be good for a couple more years now.
