I think there's some selection bias as Seagate drives are fairly abundant in oem systems where the oems included the lowest tier drive possible to shave some cost off which may be less well built and more susceptible to damage over time from vibration/impacts than higher tier drives.

I suspect that most of the time after a hard drive failure the drive gets replaced with a higher tier drive (typically from another manufacturer like WD as the person feels burnt by Seagate for having a hdd failure) which may prove more reliable.

That's my wild speculation anyways.
