Internal Hard Disk Drives

Serial Attached SCSI (SAS) provides a superior storage solution. With some storage requirements escalating and others becoming more complex, factors such as flexibility, performance, increased reliability, greater density, security, scalability and accessibility are more critical than ever. Today's organizations consist of different kinds of environments. Enterprise data centers must be online almost 24X7, fulfill requests from numerous users simultaneously, and allow for constant growth and expansion while in operation. Other customer environments require high capacity storage and high data availability for low I/O environments. HP's portfolio of SAS drives meets all these demands.

Increase the storage capacity of your system with the 600GB Hard Drive from Dell. Offering a rotational speed of 15K RPM, this drive provides fast disk access. Featuring SAS interface, this hard drive delivers enhanced data transfer speeds.

- Offers - 600GB capacity to store large amount of data

Increase the storage capacity of your system with the 300GB Hard Drive from Dell. Offering a rotational speed of 15000 RPM, this drive provides fast disk access.

WD RE Enterprise SATA Hard Drives
Ideal for enterprise servers and storage, video surveillance, and other write-intensive applications, WD RE 7200 RPM Enterprise SATA hard drives offer up to 4 TB capacity,
64 MB cache, 4th generation vibration tolerance and 5-year limited warranty.
A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional
electromagnetic actuator principles. The secondary actuator uses piezoelectric
motion to fine tune the head positioning to a higher degree of accuracy.
