The QNAP TDS-h2489FU is a 2U rackmount 24-bay NAS powered by dual Intel 3rd Gen Xeon Silver 4300 processors with up to 1TB of DDR4 ECC RDIMM. The TDS-h2489FU is best described as a quick NAS for SMB and edge locations. Built with the idea in mind that people need quick random read and write, and although it isn't the fastest NAS in QNAP's portfolio, it does offer a great solution for modern data centers, virtualization, and backup/restore tasks with up to 64Gb/s bandwidth.
