As one of its daily deals, Newegg offers the Western Digital 4TB Serial ATA 6Gb/s Internal Hard Drive 2-Pack, model no. WD40EFRX, for $299.99 with free shipping. That's tied with our October mention of a 2-pack and the lowest total price we could find for this quantity by $26. (We saw a single hard drive for $125 shipped on Cyber Monday.) Each drive features a 64MB cache. Deal ends today.
