Dual U.2 NVMe PCIe Gen 3 x4 SSD slots for optimal I/O and low latency
The TS-h973AX has four 2.5-inch SSD slots – with slots 1 & 2 supporting both high-performance U.2 NVMe PCIe Gen 3 x4 SSDs or economical SATA 6Gb/s SSDs. For tackling latency-sensitive applications, you can take advantage of U.2 NVMe PCIe Gen 3 x4 SSDs that supply up to 32Gb/s bandwidth to attain optimized performance and efficiency. You can also use QNAP’s QDA-UMP adapter to replace U.2 NVMe SSDs with cost-efficient M.2 NVMe Gen 3 x4 SSDs to maintain high-level performance while saving more costs.
Note: U.2 SSDs cannot be installed in the SATA drive bays (including the 3.5-inch bays and SSD Slots 3 & 4).
