PCIe 2.0 X4 to M.2 Cached NVMe RAID Adapter
The Areca ARC-1203-2N NVMe Native RAID host adapter is a PCIe 2.0 x4 bus to 2 ports PCIe 2.0 X1 M.2 disk array host adapter. When properly configured, the M.2 RAID adapter can provide a high degree of performance and fault tolerance with data mirroring for maximum protection. The ARC-1203-2N NVMe RAID adapter is ideal for NVMe boot applications as it naturally provides operating system and recovery data protection that is physically isolated in the system from volume user data. This isolation is critical for applications that require reliable access to the logs and OS boot programs without any chance of being corrupted by user data.
