HGST Ultrastar 7K4000 HUS724040ALE640 4TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Enterprise Hard Drive
HGST - formerly Hitachi, offers up customers in its rather bland-sounding 7K4000 series a bunch of high-capacity enterprise drives. While the name doesn't sound as fancy as "constellation," these drives are still excellent high-capacity drives, featured with a modest 64MB cache for easy storage of indexes and recent files, a 7200RPM clock speed with SATA 6Gbps connectivity for maximum speeds, and of course an extended 5-year warranty to back HGST's promise of reliability for the long-term with these drives. Though a tad pricey, this drive is a good choice for those who need high-capacity storage and enterprise reliability.
