I have a RAID 1+0 setup (4 drives, 600Gb, redundant) as my main storage, then a RAID 0 (2 drives, 640Gb, non redundant) for backups and expendable data like browser caches and swap files. All 6 drives are internal.

I did have some initial problems with Seagate SATA drives. One was DOA and the other was reporting a S.M.A.R.T. error within 24 hours. Both were exchanged without fuss and the 4 I have now have not skipped a beat.

In the RAID 1+0 array, I'm using Seagate drives, manufactured in 3 different countries/batches (to avoid the chances of a bad batch resulting in near simultaneous failure of more than one drive). In the RAID 0 array I'm using Western Digital as further redundancy against any nasty bugs the Seagate SATA firmware may have.

Anyway, before considering redundancy you should also look at environment. Are your drives sufficiently cooled? My case has a large fan at the front of each stack of 3-4 drives which keeps them "metal cool" rather than warm or even hot.
