Adaptec ASR-6805E RAID Controller Card PCIe SATA 6Gb

Adaptec ASR-6805E is a hardware RAID controller card that provides 6Gb/s SAS/SATA connectivity for up to eight internal drives over a PCIe 2.0 x4 interface. It includes 128MB of DDR2-800 cache to accelerate I/O and supports multiple RAID configurations, including RAID 0, 1, 1E, 5, 5EE, 6, 10, 50, 60, plus JBOD. This plug‑in card is designed for entry‑level servers and storage enclosures and is compatible with SATA and SAS disks and backplanes rated for 6Gb/s; it ships with a low‑profile bracket suitable for compact systems. Part of Adaptec's Series 6E family, the ASR‑6805E delivers true hardware RAID performance for improved reliability over software RAID, with management via Adaptec MaxView Storage Manager and broad operating‑system support including Linux and FreeBSD through open‑source drivers. The 6805E is commonly used in server closets, home labs, and small business NAS setups to combine multiple drives into resilient arrays without relying on motherboard‑based controllers.
