HP SAS (Serial Attached SCSI) HDDs (Hard Drives) are high-performance alternatives to SATA hard drives. SAS hard drives combine high-bandwidth and faster data transfer rates with better error detection and recovery, as well as having higher reliability specifications. SAS based hard drives are ideal for projects requiring transactional applications and performance oriented requirements where throughput and reliability are an absolute must.
- "Star" topology (point-to-point, no hubs). Each device gets full bus bandwidth.
- Higher hard drive performance compared to typical SATA drives
- Higher hard drive reliability compared to typical SATA drives
- Minimum device arbitration overhead
- True full duplex communications, transfers both read and write data simultaneously on 1 port.
