Areca ARC-1203-2N PCIe 2.0 X4 to M.2 Cached NVMe Hardware 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.

It presents RAID arrays as a single logical drive to the operating system, ensuring broad compatibility with Windows, Linux, or BSD.

Some systems may struggle with software RAID during boot, while hardware RAID offers seamless integration.

Compared to more advanced controllers with cache and battery backups, the ARC-1203-2N is affordable.

• RAID 1 for Boot Drive Redundancy Many users install their operating systems on a RAID 1 array for redundancy .
• If one drive fails, the system can continue running on the mirrored drive, minimizing downtime.
• This is particularly useful for servers or workstations that require high uptime.
