Picking a hard drive is not just about speed or size. In fact, it exceeds those two points to performance and durability. These four factors together are what determine the best hard disk drive (HDD) that you can trust for storing your important data and facilitating your digital life.
If your priority in internal hard drives is quality and durability, your choices will narrow down to the drives released by three most prominent high-authority manufacturers; HGST (aka Hitachi GST), Western Digital and Seagate. These manufacturers are well-known to produce the most reliable hard drives.
If there's one company who should know hard drives better than most, it's Backblaze, a cloud backup firm that uses more than 27,000 off-the-shelf hard drives for to run its own Storage Pods.
Judging by annual failure rate alone, Hitachi comes out the clear victor, with Western Digital in second place and Seagate a distant third, with a nearly 14 percent failure rate for its 1.5TB hard drives, but significantly less for the 3TB and 4TB models.
