What are the key specifications of the HP 636458-001 SSD?

The HP 636458-001 features 100GB MLC NAND capacity, SATA 3Gb/s interface, and 2.5-inch SFF form factor. It supports sequential reads up to 250MB/s and random 4K read IOPS exceeding 20,000, optimized for enterprise servers like ProLiant Gen8/Gen9 with hot-swap bays.

Is the 636458-001 suitable for virtualization workloads?

Yes, its MLC technology and high endurance make it ideal for VMware ESXi or Hyper-V hosts. The 100GB capacity handles multiple VMs efficiently, with low latency for boot storms and consistent performance under sustained loads in data centers.

What form factor and interface does it use?

2.5-inch Small Form Factor (SFF) with standard SATA 3Gb/s connector. Compatible with 2.5-inch drive bays in HP servers; some listings note LFF 3.5-inch variants, but primary is SFF for density.

How does MLC flash benefit enterprise use?

MLC provides higher density and cost-effectiveness than SLC, with endurance rated for 3-5 DWPD in read-heavy scenarios. It outperforms HDDs in random access, crucial for databases and caching, while maintaining reliability over 2+ million hours MTBF.

What servers is it compatible with?

Designed for HP ProLiant DL/ML Gen8 and Gen9 servers including DL360, DL380, ML350. Supports smart carrier (SC) hot-swap; verify firmware for full integration in RAID controllers like Smart Array P420i.

Does it support power-loss protection?

Yes, enterprise SSD features include power-loss protection capacitors, ensuring data integrity during outages. Combined with wear-leveling and ECC, it safeguards against corruption in mission-critical applications.
