What are the key performance specs of the HPE 704637-001 SSD?

The HPE 704637-001 delivers sequential reads up to 500 MB/s and writes up to 450 MB/s over SATA 6Gbps. Random 4K performance reaches 80,000 read IOPS and 40,000 write IOPS, with 1 drive-write-per-day (DWPD) endurance for 3 years, making it suitable for sustained enterprise workloads in servers.

Is the 704637-001 compatible with HPE ProLiant servers?

Yes, this 2.5-inch SATA SSD is validated for HPE ProLiant Gen8 and Gen9 servers including DL360, DL380, and ML350 models. It installs directly into standard hot-swap bays without adapters, supporting RAID configurations via Smart Array controllers.

What workloads is this SSD optimized for?

Optimized for mixed read/write workloads like virtualization, databases, and boot volumes. MLC NAND provides balanced endurance and cost, outperforming consumer TLC SSDs in 24/7 datacenter use with power-loss protection.

What is the form factor and interface details?

Standard 2.5-inch/7mm enterprise form factor with SATA 6Gbps (SATA III) interface. Backward compatible with SATA 3Gbps/1.5Gbps, includes self-encrypting drive (SED) readiness and thermal monitoring.

How does power efficiency compare in datacenters?

Consumes 2.5W active and 0.75W idle, significantly lower than HDDs, enabling higher storage density. Supports advanced power states for reduced TCO in large-scale HPE BladeSystem or Synergy deployments.

What reliability features does it include?

Enterprise-grade MLC with ECC, wear-leveling, and over-provisioning. Rated for 1.3 million hours MTBF, includes end-to-end data protection and automatic bad block management for mission-critical reliability.
