Frequently Asked Questions

What is SAS 24Gb/s and what advantage does it provide over SAS 12Gb/s?

SAS 24Gb/s (Gen5 SAS) doubles the per-lane interface bandwidth from 12Gb/s to 24Gb/s compared to SAS 12Gb/s (Gen4 SAS). This provides higher sequential throughput and better queue depth handling for NVMe-class SAS SSD workloads. SAS 24Gb/s drives are backward compatible with SAS 12Gb/s controllers but will operate at SAS 12Gb/s speeds on older controllers.

When should Write Intensive SSD be chosen over Mixed Use SSD?

Choose Write Intensive (WI) SSDs when your workload has a sustained write ratio of 70% or greater — such as OLTP database transaction logs, high-frequency write caches, streaming write applications, or write-ahead logs. WI SSDs provide 3-10x higher DWPD endurance than Mixed Use SSDs at the cost of lower capacity per dollar. For balanced read/write workloads, Mixed Use SSDs provide better value.

Is 400GB sufficient capacity for write-intensive workloads?

For dedicated write-intensive use cases like transaction logs, journal volumes, and write caches, 400GB is typically sufficient — these workloads prioritize endurance over raw capacity. For combined write-intensive workloads requiring higher capacity (database storage combining data and logs), consider larger Write Intensive SSDs or tiered storage combining WI SSDs for logs with higher-capacity Mixed Use or Read Intensive SSDs for data.

The HPE P26299-001 delivers 400GB of SAS 24Gb/s Write Intensive SSD storage with Smart Carrier hot-swap capability — providing the highest write endurance and dual-port SAS 24Gb/s bandwidth for HPE server write-intensive workloads including OLTP transaction logs, high-frequency write caches, and write-dominant applications requiring maximum DWPD endurance in a 2.5-inch SFF form factor.
