146 GB 15 000 RPM SAS drive for servers

This 2.5-inch HP drive delivers 146 GB of storage at 15 000 RPM for high-transaction workloads. The dual-port SAS 600 interface supports multipath I/O and hot-plug capability in compatible enclosures. It is built for enterprise arrays that demand consistent low-latency access.

SAS 600 interface limits

The 600 MBps maximum external transfer rate is the ceiling for sustained sequential throughput on this interface. Dual ports provide redundancy, not aggregated bandwidth, so a single stream cannot exceed the link speed. Cable length and backplane quality also affect real-world performance.

Verify controller and bay compatibility

Confirm your RAID controller or HBA supports 6 Gb/s SAS and 2.5-inch 9.5 mm high drives. The 100.3 mm length must fit your drive tray or backplane slot. Ensure firmware and driver revisions are current for the 512547-S21 part number.
