Perc H310 Raid Controller

The Dell PERC H310 (Series 8) is a 6Gbps SAS/SATA RAID controller that has evolved from a basic entry-level enterprise component into the "budget king" of the software-defined storage market. Its value in 2026 is primarily driven by its unique hardware versatility and its role in "homelabbing" and secondary market applications DellProdisknetwork.

1. Key Product Insights

* Hardware Profile: It features the LSI SAS2008 chipset and PCIe 2.0 x8 interface Dell. Unlike higher-tier models (H710/H810), it lacks an onboard cache and battery backup (BBU), which makes it less suitable for performance-heavy hardware RAID (like RAID 5/6) but highly reliable for long-term use without maintenance ProdisknetworkDell.

* The "IT Mode" Factor: The most significant market driver for this card is its ability to be "flashed" to LSI IT Mode (Initiator Target). This converts it into a pure Host Bus Adapter (HBA), allowing operating systems like TrueNAS, Unraid, and Proxmox to have direct access to drives for ZFS or software RAID ProdisknetworkFohdeesha.

* Capacity Support: While originally designed for earlier server generations, it supports modern high-capacity drives (tested up to 18TB+) when flashed to IT mode, bypassing the older 2TB limits of legacy firmware SuperuserReddit.

2. Market Trends & Pricing

* Secondary Market Dominance: The H310 is widely available on the secondary market as a "pull" from retired enterprise servers (e.g., Dell R620/R720). Prices typically range from $15 to $45 depending on the form factor (Adapter card vs. Mini Mono) EbayEbayItcreations.

* B2B/Wholesale Stability: Wholesale pricing for refurbished units in bulk (50+ units) can drop to $10–$15 per piece, making it a cost-effective choice for system integrators building budget storage arrays or white-box servers.

* Market Growth (RAID Controllers): The broader RAID controller market is projected to reach $12.18 billion by 2031 Mordorintelligence. While new systems use PCIe Gen5 (H755/H965), the H310 remains a stable sub-niche for legacy support and low-cost DIY infrastructure.
