• Form factor: 2.5-inch SFF — fits modern server bays and high-density enclosures.
• Interface: SAS 12 Gb/s — enterprise-grade protocol with robust command set and multipath support.
• Workload profile: Read-intensive (RI) — optimized firmware for predictable read performance.
• NAND type: Enterprise-grade multi-level cell (MLC) / TLC 3D NAND (controller and exact NAND may vary by production batch).
• Endurance class: Read-Intensive / Sc (Single Controller?) MV — designed to deliver years of service under read-major workloads.
• Included tray: Hot-swap carrier/tray for tool-less insertion and secure mounting in HPE bays.

Choose a read-intensive SAS SSD like the P49742-001

Read-intensive SAS SSDs strike a balance between cost-per-gigabyte and enterprise features. They are tailored for databases and applications that are read-heavy — for example: web caches, content delivery nodes, real-time analytics indexes, large-scale virtualization read operations, and software-defined storage read caches. Compared with endurance-focused write-intensive drives, read-intensive models deliver lower cost while retaining critical enterprise features such as power-loss protection, SMART telemetry and robust error correction.

Typical workloads

• Analytics platforms with frequent random reads (OLAP).
• Content delivery networks (CDN) and large object stores optimized for reads.
• Virtual desktop infrastructure (VDI) read-heavy boot storms.
• Database read replicas and reporting instances.
• Search indexes and metadata stores.
• Cache acceleration layers in hybrid storage configurations.

Reliability, durability and enterprise features

Enterprise SSDs are judged not only on raw speed but on predictable behavior under sustained load. The P49742-001 includes multiple layers of reliability engineering — from NAND wear management and over-provisioning to advanced error correction, power-loss protection, and drive-level SMART metrics that integrate with HPE iLO and storage management suites. Warranty and support are aligned to enterprise expectations when deployed through HPE channels.

Drive-level safeguards

• Power-loss data protection: On-board capacitors and firmware ensure in-flight data integrity on unexpected power events.
• End-to-end data path protection: CRCs and internal checks protect against silent data corruption.
• Thermal throttling and monitoring: Prevents overheating and prolongs NAND lifespan.
• SMART reporting: Integrates with monitoring tools for pre-failure indicators and fleet health analysis.

Compatibility and integration: servers, arrays and trays

The SAS-12Gb/s interface ensures wide interoperability with HPE ProLiant servers, HPE storage enclosures and many enterprise-class controllers. The included drive tray simplifies cross-compatibility with HPE drive carriers — important for hot-swap environments and serviceability. Always verify firmware compatibility for specific storage controllers and array models; HPE frequently publishes firmware bundles and compatibility matrices to guarantee best-in-class behavior.

Deployment considerations

• Confirm HPE controller and array firmware compatibility prior to large-scale rollout.
• For mixed-drive enclosures, use placement strategies (tiering or dedicated pools) to keep read-intensive drives in the appropriate tier.
• Enable SMART and telemetry ingestion via HPE tools (iLO, OneView, or array management) for proactive maintenance.

Data-center design: tiering, caching and hybrid storage

The P49742-001 is ideal as part of a tiered storage strategy. By placing read-intensive SSDs in a hot tier and using higher-capacity HDDs for cold data, organizations can optimize cost and performance. When used as a read cache in front of magnetic storage, the drive can dramatically reduce read latency for frequently accessed objects while lowering total cost compared to a pure all-flash approach.

Tiering strategies

• Hot tier: Read-intensive SSDs for frequently accessed datasets and index structures.
• Warm tier: Mixed-use SSDs or high-performance NL-SAS HDDs for less frequently-accessed but performance-sensitive data.
• Cold tier: High-capacity HDDs for archive and long-term retention.

Read-intensive vs Mixed-use vs Write-intensive SSDs

• Read-intensive (this product): Best value for read-heavy workloads — optimized firmware and endurance for reads.
• Mixed-use: Balanced read/write endurance and slightly higher cost — suitable for general-purpose virtual machines and transactional databases with balanced profiles.
• Write-intensive: Highest endurance and often highest cost per GB — needed for heavy-write DBs, logging layers, and caching write-back scenarios.

2.5" SAS SSD vs NVMe SSD

NVMe drives provide lower latencies and higher parallel throughput for ultra-high-performance workloads, but SAS SSDs like the P49742-001 retain advantages for many enterprise environments:

• Compatibility: SAS works with existing HBA/backplane infrastructure and multipath stacks in mature data centers.
• Management: SAS integrates cleanly with legacy monitoring and storage systems without requiring PCIe/NVMe host changes.
• Cost: SAS SSDs often offer better cost-per-GB for enterprise-capacity models at mainstream performance levels.
• Use case fit: For read-heavy, high-capacity tiers, SAS remains a pragmatic choice.

Buying guide: how to select the right SSD variant

Choose based on workload profile (read vs write balance), capacity needs, and integration requirements with your storage controllers and management stack. If you need the lower latency and parallelism of NVMe for certain workloads, evaluate NVMe alongside SAS SSDs; for many enterprise read-heavy tiers, the P49742-001 presents a compelling balance of capacity, compatibility and cost.

Checklist before purchase

• Confirm SAS controller supports 12Gb/s and the required drive feature set.
• Decide desired usable capacity after RAID/protection overhead.
• Plan for firmware and monitoring integration with HPE OneView, iLO or your monitoring stack.
• Validate warranty and RMA options with your procurement channel.
