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

Serial ATA NCQ Hard Drives maximize performance by providing faster data transfer speeds, better system cooling airflow, more bandwidth, more headroom for speed increases in future generations and better data integrity.

Supply your Proliant server a Genuine HP Compaq Hard Drive and you will prevent incompatibilities that can rob your system of performance or cause you to lose valuable data. This Hard Drive is designed for any Ultra320, Ultra3 or Ultra2 capable ProLiant Server, ProLiant Storage System, AlphaServer or StorageWorks Hot-Plug enclosure.Minimize

The IBM (39M4514) 500 GB SATA Hard Drive is fully compatible with PC systems. Offering capacity as large as 500 GB
