I normally purchase Seagate for desktops and Hitachi, Samsung or Toshiba for laptops for my clients or personally hard drive replacement and/or upgrade. But this month I had no choice but to purchase some WD's drive due to supply from my wholesaler. Well so far 2 of those WD's have come back already defective, one 3.5" drive and one 2.5" drive. So I take it WD has not changed when it comes to reliability. Last WD drive I purchase!!!
