  "IBM presents the sixth generation of IBM Ultrastar 10,000 rpm disk drives. The IBM Ultrastar 146Z10 drive family offers high quality and superior performance. These drives feature more powerful processors and read/write channels to excel in server-class environments. To achieve maximum I/O performance, the drives combine fast seek times, large 8 MB multi-segmented buffers, a sophisticated command queuing algorithm, hardware automation, and superior data rates (825 Mbps). Ultrastar 146Z10 drives include a servo technology (Rotational Vibration Safeguard ""RVS""), employed to counteract the effects of rotational vibration that commonly occur in multi-drive cabinets. They also employ a fifth-generation giant magnetoresistive (GMR) head technology to double areal density from previous generation drives (26.3 Gbits/sq.in.) and boost performance. In addition, highly efficient No-ID sector formatting enables more data to be stored per disk.Feature Value Header / Product Line  IBM UltraStar  Header / Model  146Z1"Minimize

?Serial Attached SCSI is the logical evolution of SCSI, including its long-established software advantage and the Serial ATA electrical and physical connection interface. SAS meets all these demands while providing the highest performance.

Cool, quiet operation, superior performance and industry-leading reliability make these SATA drives ideal for desktop, business, and consumer electronics storage.

Double your throughput in select IBM eServer xSeries servers with the next generation of high-speed Ultra320 SCSI hard disk drives (HDDs), now with the new Ultra-Slim tray form factor. Ultra320 SCSI drives provide top-of-the-line performance for business-critical, disk-intensive applications such as e-business, transaction processing, data mining and data warehousing. Ultra320 SCSI technology combines interface data transfer rates of up to 320MBps, reduced overhead and enhanced flow control to help deliver dramatic performance gains. Improved diagnostics and data protection, as well as hot-swap capabilities with direct docking, help reduce downtime. For even greater reliability, you can create high-performance RAID arrays. Simply connect your drives to either an onboard Ultra320 SCSI controller with integrated mirroring capabilities or an IBM ServeRAID-5i Controller, available on select xSeries servers.Minimize

Cool-running, quiet operation, superior performance and industry-leading reliability make the WD Caviar SE drives the perfect hard drives for desktop and enterprise storage.
