I am about to buy new hard disk for my laptop, I have been considering various option. I have also option to upgrade to 240 GB SSD . I am told that only buy reputed brand like Intel , Samsung or Crucial and stay away from others. So after looking online, I can find two hard drives which I have shortlisted from Samsung, one is
Samsung 840 EVO series and other is Samsung 840 PRO series. On online store, both disk comes with 3 years limited manufacturer warranty and have almost same specifications. But Pro series is about 20% costlier than EVO series.
Before buying it, I need to know what is exact difference and why PRO series is costlier than EVO series ?
