HGST Deskstar NAS 3.5-Inch 4TB 7200RPM SATA III 64MB Cache Internal Hard Drive Kit (0S03664)

The Deskstar NAS hard drive is a 7200 RPM 3.5-inch hard drive that provides an exceptional blend of reliability and performance, making it an ideal solution for consumer and commercial desktop NAS systems. This NAS-ready hard drive from HGST delivers media transfer rates that are as much as 20% faster than 5400 RPM drives and seek times less than 12ms. Furthermore, Deskstar NAS hard drives incorporate a rotational vibration sensor and achieve reliability of one million hours MTBF.

The Deskstar NAS comes available in storage capacities up to 4TB for room to grow as your networked content grows. This HGST hard drive runs at a speedy 7200 RPM, with a 64MB cache buffer for fast data access. SATA III provides up to 6Gbit/sec data bandwidth rate for rapid file transfers and backups.

One of the greatest hindrances to hard disk performance is vibration. Like a needle on a record, the disk drive’s head must try to follow narrow data tracks in order to read (or write) information. These problems are particularly acute in multi-drive systems, because drives tend to be installed alongside each other, in arrays. The vibration caused by the rotation and seek activities of nearby drives can affect the whole array, progressively disturbing the operation of each drive in the system. The drop in performance can be significant. That's why the Deskstar NAS hard drive has an advance Rotational Vibration Safeguard (RVS) that anticipates disturbances and counteracts them, maximizing performance in the most arduous conditions. If the RVS sensors feel a vibration rippling through the drive, they send a signal to the actuator that controls the head’s position. The actuator then compensates for the disturbance, counteracting it with an equal and opposite force. In this way, the head is able to "ride" the vibration and stay on track, helping to prevent data loss or corruption.

All HGST hard drives are designed to the highest quality standards with field-proven components. With one million hours of MTBF, a rotational vibration sensor, and 24/7 availability, the Deskstar NAS hard drive is an ideal choice for backing up and sharing content at home or at the office.

The Deskstar NAS system is compatible with both Windows and Mac desktop PCs. Windows users will need a computer system running Windows Vista/7/8/8.1 and an available SATA port. Macintosh users will need a Mac computer running OS X 10.5 or newer and an available SATA port. The package comes with everything needed for installation, with no additional hardware required.
