John dual boots with Windows 7 and Windows 10 on separate SSDs. Now the SSDs have died. When he replaced them, his power supply died. Did the hard drives do it? Leo says that the power supply may have contributed to the SSDs dying, but not the other way around. After replacing it, his spinning hard drive has died in less than a year. Leo says that large capacity hard drives can die at any time, and the older they get, the more likely they will. They might not fail, though. But after less than a year, it's odd. Leo thinks that it's likely the higher density drives, which Steve Gibson says make him nervous. Leo recommends also going with a NAS, with smaller drives in a RAID configuration, so he can just replace them. Getting an enterprise drive will give him better performance. Like the Western Digital Caviar drives.
