Comparison with Other Storage Tiers

Versus Read-Intensive SSDs

Compared to HPE's Read-Intensive SSDs, the P41547-001 Mixed Use drive offers significantly higher write endurance (3 DWPD vs. 1 DWPD for Read-Intensive models) and better sustained write performance. While Read-Intensive drives are more cost-effective for predominantly read-oriented workloads, the Mixed Use variant maintains consistent performance under write-heavy bursts common in mixed workload environments. The additional endurance comes from higher over-provisioning and more sophisticated wear-leveling algorithms.

Versus Write-Intensive SSDs

While Write-Intensive SSDs offer even higher endurance (typically 10+ DWPD), they command a significant price premium and may provide lower read performance compared to Mixed Use drives. The P41547-001 strikes an optimal balance for the majority of enterprise applications that don't require extreme write endurance but need better performance than Read-Intensive drives can deliver. For most mixed workload scenarios, the Mixed Use category provides the best price-to-performance ratio.

Versus SAS and SATA SSDs

The NVMe interface provides substantial performance advantages over SAS and SATA SSDs, with approximately 6x lower latency and 4x higher IOPS compared to SAS SSDs. The PCIe 3.0 x4 interface offers up to 4GB/s bandwidth compared to 1.2GB/s for 12Gbps SAS and 0.6GB/s for SATA 6Gbps. This performance differential becomes particularly noticeable in mixed workload scenarios where multiple operations occur concurrently, making NVMe the clear choice for performance-sensitive applications.
