HP 146GB SAS 15K 2.5 Drive

This 146GB SAS hard drive spins at 15000 RPM and uses a 2.5-inch form factor. It is built for enterprise servers that demand high transaction throughput. The dual-port SAS interface supports 6G speeds for reliable data integrity. It suits IT teams running mission-critical workloads on HPE hardware.

Dual-Port SAS Server Integration

The drive fits 2.5-inch SFF bays with standard hot-plug or non-hot-plug carriers. Its SAS interface connects directly to compatible RAID controllers or backplanes without extra adapters. Dual-port architecture provides path redundancy for continuous availability. It frees up 3.5-inch LFF slots for higher-capacity midline drives.

146GB Capacity For Hot Data

The 146GB capacity handles operating systems, databases and high-IOPS applications comfortably. It runs out when workloads exceed 600GB or require 1.8TB 10K alternatives. Heavy media archives or backup targets need larger 7.2K LFF drives. This drive targets the performance tier, not bulk storage.
