P440ar Raid
Overview
Product sourcing insights & recommendations
The HPE Smart Array P440ar is a performance-tier 12Gb/s SAS RAID controller primarily used in HPE ProLiant Gen9 servers. As of 2026, the product is officially Retired/Obsolete, with availability limited to refurbished units on the secondary market.
Key findings from the market analysis include:
- Technical Specs: It features a 2GB Flash-Backed Write Cache (FBWC) and supports advanced RAID levels (including 10 ADM) and SSD acceleration via SmartCache.
- Market Trends: The global RAID controller market is growing at a 6.0% CAGR, but demand for the P440ar is strictly tied to legacy Gen9 infrastructure maintenance.
- Pricing: Refurbished units are widely available on B2B platforms, with prices ranging from $10 to $100 depending on the configuration.
- Evolution: Newer models like the P408i-a (Gen10) introduced "Mixed Mode" for simultaneous RAID/HBA operations, while Gen11 has transitioned to "Tri-mode" controllers supporting NVMe.
