NCIX offers the Western Digital Red 3TB Serial ATA 6Gb/s Internal Hard Drive, model no. WD30EFRX, for $139.99 with free shipping ($0.05/GB). That's tied with yesterday's mention (which was after rebate) and the lowest total price we've seen for this drive without rebate hassles. This internal hard drive is optimized for use in 1- to 5-bay NAS systems and features a 64MB cache.
