2.5GbE ConnectivityConnect the dual 2.5G RJ45 Ethernet ports to compatible devices for bandwidth-intensive tasks such as large backups, data restoration, and media transfers.
Optimized Data SpeedsInstalling up to two M.2 NVMe solid-state drives reduces latency for storage volumes to help improve the overall performance for data-intensive applications such as databases and virtualization.
Qtier TechnologyWith Qtier 2.0, the TS-873A-8G uses auto tiering to continually optimize storage efficiency by automatically moving data between the M.2 SSDs and the installed 2.5″/3.5″ drives based on how frequently the files are accessed. Qtier 2.0 features IO-awareness that maximizes SSD-tiered storage performance with a cache-like reserved space to handle burst I/O in real-time.
USB ConnectivityThree 10 Gb/s USB 3.2 Gen 2 Type-A ports are available alongside one 5 Gb/s USB 3.2 Gen 1 Type-C port, allowing you to connect compatible devices such as storage drives and other peripherals.
