Adaptec RAID 8805 Components 2277500-R - 12Gb/s MD2 RAID Adapter

In this review of the Adaptec RAID 8805 Components 2277500-R the bottom line is simple: this is a focused, enterprise-oriented RAID adapter for builders who need reliable high-throughput storage connectivity. The review finds the card best suited to server and workstation environments that demand fast, low-latency access to multiple SAS or SATA drives. Its primary selling point is the combination of 12Gb/s per port throughput and an 8-lane PCIe Gen3 interface in a compact MD2 low-profile card, which keeps dense storage bays running efficiently without taking a full-height slot.

Key Features

• 12Gb/s per port: Delivers sustained throughput for multi-drive arrays so large datasets and backups complete faster.
• 8-lane PCIe Gen3 interface: Provides a high-bandwidth connection to the host system that reduces transfer bottlenecks under load.
• MD2 low-profile form factor: Fits compact servers and workstations where space is limited while still providing eight internal native ports.
• 1024MB cache memory: On-board cache helps smooth burst transfers and improves write performance for RAID arrays.
• Efficient power characteristics: Documented operating voltages indicate modest power draw for data center deployments and constrained systems.

Who It's For

The RAID 8805 is aimed at IT professionals, system integrators, and advanced home lab users who need an internal RAID controller with eight native ports and high per-port bandwidth. It is a good match for small to medium business servers, multi-drive RAID arrays, and storage-dense towers where a low-profile card is required.

It is less appropriate for casual desktop users who only need one or two drives or who prefer software RAID solutions; likewise, those requiring external SAS ports or broad compatibility guarantees across every OS should verify driver support before purchasing.

Pros & Cons

Pros

• High per-port transfer rate supports demanding storage workloads and multi-drive arrays.
• LP/MD2 form factor allows installation in compact chassis and rack servers with limited slot height.
• Generous 1024MB cache helps maintain write performance and reduces latency for bursts.

Cons

• Designed as an internal adapter with eight native internal ports, so it does not provide external drive connectivity without additional hardware.

Specifications

Our Verdict

The Adaptec RAID 8805 is a practical choice for professionals who need a compact, high-throughput internal RAID controller with eight native ports and meaningful on-board cache. It represents solid value for server and storage builds that require sustained 12Gb/s connectivity per port and an MD2 low-profile footprint, provided drivers and compatibility meet the target platform.
