R0Q56A - HPE MSA 1.8TB SAS 10K SFF M2 HDD

HPE R0Q56A — MSA 1.8 TB SAS 12G 10K SFF HDD

What it is

R0Q56A is an HPE enterprise-class hard disk drive designed for HPE MSA (Modular Smart Array) storage systems.
It’s a 1.8 TB SAS 12 Gb/s, 10 000 RPM small form factor (2.5″ SFF) mechanical drive built for performance-balanced storage tiers where responsive throughput, efficient capacity, and enterprise reliability matter.

Why buyers pick R0Q56A (plain English)

Balanced performance with usable capacity
1.8 TB gives you a good amount of storage while keeping the drive fast and responsive — ideal for mixed application tiers and general workload storage.

Enterprise SAS interface
Dual-ported SAS 12 Gb/s delivers reliable throughput, strong error handling, and redundancy in shared storage arrays.

10 000 RPM responsiveness
Faster rotational speed than 7.2 K drives means better IOPS and throughput for transactional and mixed workloads without the cost of flash.

MSA-validated compatibility
Designed and tested for HPE MSA arrays, ensuring predictable behavior, firmware compatibility, and supportability.

Hot-plug capable
Supports hot-swappable insertion and removal in MSA drive bays so upgrades and maintenance can happen with minimal service disruption.

Where it fits (and when to choose something else)

Perfect for:

• HPE MSA arrays with 2.5″ SAS bays

• Mixed transactional workloads where more performance is needed than 7.2 K HDDs

• Enterprise storage that balances capacity with responsiveness

• Shared storage tiers supporting virtualization, databases, and mixed I/O

Choose something else if:

• You need the lowest latency and highest IOPS → SSD or NVMe tiers

• You want maximum capacity per bay → 7.2 K LFF HDDs

• You require very high performance → SAS SSDs

TL;DR

R0Q56A is HPE’s 1.8 TB SAS 12G 10K SFF HDD for MSA arrays:
a hot-swap, enterprise-class mechanical drive tuned for balanced performance and capacity in mixed application storage tiers.
