"1,240 10+TB hard disks installed, and not a single one has gone bad." <quote> Traditionally, the expected pattern of hard disk failures has been the so-called "bathtub curve:" a spate of failures of new disks ("infant mortality"), as disks that were defective from the factory are shipped into the wild and rapidly stop working, followed by a long period of low failure rates, and then an uptick in failures as the disks pass their engineered lifetime.
The initial data from the 10TB and 12TB disks, however, has not shown that pattern. While the data so far is very limited, with 1,240 disks and 14,220 aggregate drive days accumulated so far, none of these disks (both Seagate models) have failed. </quote>
It's early days yet, these haven't been hammered with use. But the lack if 'infant mortality" is interesting.
I don't think that's a fair summary of the data in the second article. Yes it shows zero failures for the Seagate 10 TB and 12 TB, but it also shows zero failures for the Toshiba and WDC 3 TB and the Toshiba 4 TB and the HGST 8 TB, so there's nothing special about the larger sizes. Indeed, given the extremely low drive-days for the 12 TB drives, it would perhaps be more remarkable if there WERE any failures. Given the absymal figures for other Seagate drives, I suppose it does go some way to rehabilitating them, but personally there's still no way I would touch anything from Seagate or WDC.
