For in-store pickup only, Micro Center offers the Seagate Barracuda 3TB Serial ATA 6Gb/s Internal Hard Drive, model no. STBD3000100, for $79.99. That's $9 under our mention of a similar drive from yesterday and the lowest total we've seen for any 3TB SATA 6Gb/s drive that runs at 7200 rpm. (It's a current price low by $9.) It also features a 64MB cache.
