“The need for greater storage capacity will continue to expand in multiple directions and dimensions, but there will be an increasing scrutiny of all storage system purchases, with an eye to decreasing power consumption, footprint, and cost per GB in unprecedented ways,” said John Monroe, a research vice president at Gartner. “Performance will not be ignored, but a flexible balance of capacity, cost per GB, power and speed will become more crucial in fulfilling end-user storage demands at varied price points.”

Both the Constellation and the Constellation ES will be featuring Seagate’s  PowerChoice technology, which decreases power consumption by up to 54% for record power savings in enterprise environments.

In addition, the Constellation family of drives are offered with optional self-encrypting drive (SED) technology and provide government-grade data security through the drive’s life cycle. According to Seagate, SED technology makes drive retirement and disposal easy by eliminating the need for the numerous manual processes.
