The problem I had with Seagate over the years is reliability or the lack of it, I have had a couple of internal Seagate drives go down on me.
i have used a few makes over the years, Conner, Maxtor, Quantum, Seagate, Hitachi and Toshiba.
My computer now have 240GB Cosari Neutron SSD, a 120GB corsair force 3, a 2TB Toshiba and a 500GB Seagate hybrid.
Externally I have a Seagate 1TB, a Toshiba 2TB which I do not trust as the smart data says it have a problem, this thread have made me look at the warranty and it is for two years, so I can still claim. i only had it for just over a year.
i also have a old 1 TB Hitachi 3.5 inch and a 8 year 1TB buffalo NAS drive which is still working, slow it may be but oh so useful. I am shocked it is still working, I have no idea what drive is in it, but I know at the time it cost me over £300
