The TurboNAS TS-1635 is a very large NAS server which under the hood features the Annapurna AL-514 quad-core Cortex-A15 CPU clocked at 1.7GHz along with 4/8GB DDR3L RAM (upgradable to 16GB), 512MB of DOM flash memory, PCIe Gen2 (x2) slot (for an extra NIC), 16 SATA 6Gb/s drive bays (12x2.5/3.5" & 4x2.5"), two 10GbE SFP+ LAN ports, 2 Gigabit RJ45 LAN ports, 3 USB 3.0 ports, built-in speaker and a line out port. You can of course configure all 16 bays of the TurboNAS TS-1635 in single, JBOD and RAID 0/1/5/6/10 + hot spare modes with AES 256-bit data encryption. Just like with other models by QNAP if by any chance the 16 SATA 6Gb/s bays are not enough to cover your needs in the long run you can expand the storage capacity of the unit with one of the available expansion models (UX-500P/UX-800P).
