I currently have a ASUS Laptop with Seagate Momentus 750Gb 7200RPM SATA HDD with 16mb cache ... it went bad after year and 8 months. Im leary about replacing it with the same unit. Comparable suggestions? It's my son's laptop and he uses it for college, some gaming and streams movies. I am considering switching to Western Digital for better warranty on a similar HDD or is there a better choice for similar $$$?
