ECC RAM Supported
ECC (Error-Correcting Code) can detect and correct memory errors, enhancing system stability and reliability. It reduces the risk of data errors, ensuring data integrity in enterprise environments. For businesses that require high reliability, consider upgrading your Flashstor Gen2 to the maximum of 64 GB of memory for enterprise servers and workstations.

USB4 – Unmatched Flexibility
The Flashstor Gen2 is equipped with two high-speed USB4 ports, offering ultra-fast speeds of up to 40 Gbps. The USB4 ports are compatible with Thunderbolt 3/4 devices, allowing you to transfer, store, archive, and back up faster than ever. When connecting two ASUSTOR NAS units using the USB4 ports, fast data transfers, synchronizations, and backups can be achieved without using the network ports. Paired with features like DataSync Center and SMB Backup, this can help significantly reduce back up time.

The Flashstor Gen2 series now incorporate an improved thermal dissipation design that includes strategically placed fans that are efficient and silent to cool every high performance component in the Flashstor Gen2 series. This optimized cooling efficiency ensures sustained high performance while maintaining low noise levels.
