Good article here:
Seagate was never affected (no plants in Thailand), but their prices went up (somewhat) as well; gotta have those profits! Actually, I watch prices of large NAS boxes, and those with Seagate drives (non-'green', Barracuda 7200rpm SATA3, 64MB cache) are actually below that of a year ago across the capacities, 2-4TB drives. Others are nowhere near same, generally 25+% higher (and we're talking about boxes in the $2-8K level).
Maybe the others (and Seagate as well) will come down, but they might become used to the record profit levels.
