NEW in original OEM packaging (SEALED “bare drive”), a 4 TB, 3.5 in. form factor WESTERN DIGITAL CAVIAR GREEN Internal Desktop Hard Drive--Model WD40EZRX (Note that I have two of these drives available, as described). As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar Green drives make it possible for customers to build systems with higher storage capacities and the right balance of Best-in-Class power management efficiency and acoustics, system performance, and ensured reliability. Quiet acoustics, reduced vibration and advanced 4K HDD formatting makes WD Green a stronger solution when compared to the competition.
