HP Solid State Drives

HP and HPE solid state drives are classified by endurance as well as by capacity, and the endurance class is the part most often got wrong. Two drives of the same size can be built for very different write loads.

Endurance classes

• Read Intensive - built for workloads that mostly read. The lowest drive-writes-per-day rating and the lowest cost per gigabyte.
• Mixed Use - a middle endurance tier for general virtualisation and database work.
• Write Intensive - the highest endurance tier, for logging, caching and heavy transactional writes.

Older HPE listings use the phrase Mainstream Endurance for a comparable middle tier. Putting a read-intensive drive under a write-heavy workload will not fail immediately; it will simply consume its endurance budget faster than planned.

Interfaces in stock

• SATA 3Gb/s and 6Gb/s - the largest part of our HP SSD inventory
• SAS 12Gb/s - dual-ported, the usual choice where controller failover matters
• NVMe - PCI Express attached, in M.2 2280 and 2.5-inch form factors

Form factor and carrier

Most enterprise HP SSDs are 2.5-inch SFF. Fitting one into a 3.5-inch LFF bay needs an adapter, and hot-plug bays need the carrier that matches your ProLiant generation - carriers changed more than once across generations and are listed separately on our HP drive caddy page.

NVMe is not a drop-in replacement for SAS or SATA. It needs bays and a backplane wired for PCI Express, which not every ProLiant has.

Send us the ProLiant model and the workload and we will match capacity, endurance class and carrier together.
