Key specifications at a glance

Capacity and form factor

Capacity: 7.68 terabytes of usable raw NAND storage in a 2.5-inch small form factor (SFF) drive height (approximately 15 mm typical for SFF enterprise drives). The compact 2.5" format allows high-density server and storage node populating while keeping power and cooling requirements manageable.  

Interface and ports

Interface: SAS 24Gb/s (SAS-24G) dual-port operation for multipath connectivity and high availability in enterprise arrays. The 24Gb/s SAS interface offers backward compatibility with earlier SAS speeds while providing headroom for sequential and random throughput improvements in multi-initiator environments. Dual-port SAS supports redundancy, failover, and active/active or active/passive topologies depending on your storage controller and firmware configuration.  

Workload class and flash type

Workload class: Read-Intensive (RI) — optimized for workloads where read operations dominate, such as analytics, boot volumes, caching layers, content repositories, and large-scale search indexes. Flash type: Typically TLC enterprise NAND in multi-vendor configurations, tuned with enterprise firmware to balance endurance, performance, and cost for RI use cases.  

Power and thermal profile

Power consumption for similar 2.5" SAS enterprise SSDs is often in the single-digit watt range under steady state (example published figures around 8.5 W depending on workload). Thermal management should be planned at the server level—adequate airflow and proper tray mounting are essential to maintain optimal performance and long device life.  

Detailed feature breakdown

Enterprise firmware and digital signing

HPE-branded drives often include digitally signed firmware and are validated for specific HPE generation servers (Gen10, Gen10+, Gen11 and beyond), which helps ensure drive compatibility, boot reliability, and consistent integration with HPE system management tools. OEM validation reduces the risk of firmware mismatches that could otherwise lead to degraded performance or unsupported states. If you run heterogeneous environments, check the exact option/spare part cross-reference (P49041-B21 is an equivalent option part number in some listings). 

Carrier/tray and hot-swap convenience

The "BC" carrier (basic carrier / drive tray) included with the P49741-001 enables hot-plug functionality and tool-less insertion/removal in HPE servers. For large installations this reduces maintenance windows and simplifies drive replacement under fault conditions; the drive can be swapped without powering down the server, preserving uptime for mission-critical systems.  

Data integrity and enterprise reliability

Enterprise SSDs such as the P49741-001 include power-loss protection strategies, end-to-end data path protection, and strong error correction code (ECC) algorithms to protect against data corruption. Although precise implementation details are vendor/firmware specific, these drives are designed for consistent low-latency reads and predictable behavior under mixed I/O, which is critical in SAN and clustered deployments. Check manufacturer documentation for details about power-loss protection capacitors and write caching behavior.

Use cases and ideal deployments

Virtualization and VDI

Read-intensive volumes in virtualized environments (boot storms, linked-clone pools, desktop images) benefit from the P49741-001's high read throughput and large capacity. Use it for capacity-optimized VM datastores where reads dominate and write amplification is limited by snapshot policies. Combined with server RAM and caching layers, the drive reduces read latency while enabling high VM density per host. 

Database indexing and analytics

Analytical databases and search indexes that perform heavy reads over large datasets will find the balance of capacity and sustained read performance useful. The SAS 24Gbps interface helps sustain consistent sequential throughput for large scanning operations and report generation jobs. For write-heavy transactional workloads, consider mixed-use or write-optimized drive classes instead. 

Content distribution and caching

CDN edge nodes, media asset storage, and read cache layers are typical placements for high-capacity read-optimized SSDs. When paired with replication and multi-path configurations, drives like the P49741-001 enable stable content delivery with minimal latency for end users.  

Compatibility and server integration

Validated platforms

This HPE spare part has published compatibility with HPE ProLiant Gen10+ and later families as a factory-approved SSD option; however, compatibility lists can vary by firmware and server BIOS versions. Always verify the drive's compatibility matrix for the exact server model and firmware revision before large rollouts. OEM-equivalent option numbers (for example, P49041-B21) may appear in procurement or inventory systems.  

Controller/RAID considerations

When using RAID controllers, choose a RAID level that matches your availability and performance needs. RAID 10 or RAID 6 are common for mixed reliability and usable capacity tradeoffs; performance characteristics of SSD arrays differ from HDD arrays—especially with random I/O—so re-tune queue depths and stripe sizes for SSD workflows. SAS dual-port enables controllers to present multipath paths for failover, which is especially valuable for clustered file systems and shared-storage arrays.  

Comparisons and alternatives

How this drive compares to NVMe options

SAS 24G SSDs prioritize compatibility with existing SAS infrastructure, dual-port redundancy, and ease of integration in enterprise backplanes. NVMe drives typically provide higher per-device throughput and lower latency but in many server designs require different backplanes, cabling, or U.2/M.2 form factors and sometimes lack the same dual-port redundancy. Choose SAS 24G when you need proven HPE server compatibility and dual-path resilience; choose NVMe when single-device latency and maximum throughput per lane are paramount. 

Alternative capacities and workload classes

If your environment has heavier writes, review mixed-use (MU) or write-intensive (WI) classes, or reduce logical writes through caching and tiering strategies. HPE and other OEMs offer a range of capacities and endurance classes; matching drive class to workload preserves endurance headroom and minimizes replacement churn.
