HP 632630-001-R 2.5" 400GB SAS 6Gb/s SLC enterprise SSD

HP 400GB SAS SLC Enterprise SSD

This HP 632630-001-R is a refurbished 2.5-inch enterprise solid-state drive with 400GB capacity. It uses single-level cell NAND and a SAS 6Gb/s interface for server workloads. The drive suits administrators who need consistent write endurance in a compact form factor. It is not intended for consumer desktop upgrades or high-capacity archival storage.

Fits 2.5-inch SAS drive bays and controllers

The 2.5-inch form factor slides into standard hot-swap trays and backplanes that accept SAS devices. A compatible SAS host bus adapter or RAID controller with 6Gb/s support is required for operation. The drive frees up 3.5-inch bays for other uses while delivering enterprise-grade connectivity. Builders without SAS infrastructure cannot use this drive.

SLC NAND sustains write performance under load

Single-level cell memory maintains steady throughput during prolonged write-heavy operations such as database logging or virtualisation workloads. The SAS 6Gb/s link provides deterministic latency without the variability seen in consumer-grade alternatives. Performance does not degrade sharply after the drive fills, unlike drives that rely on dynamic cache folding. Workloads needing multi-terabyte capacity will exceed this drive's 400GB limit.
