Intel® quad-core CPU with built-in GPU
2x M.2 NVMe slots for SSD caching
2x 2.5GbE, 1x PCIe slot for 10GbE expansion
TS-664 is a compact 6-bay NAS with superior performance. Supporting up to 110 TB storage and 4 TB M.2 SSD caching* at an affordable price, the TS-664 fulfills your multitasking challenges for file management, backup, collaboration, and video conversion.
The TS-664 uses the QTS operating system by default. You will be able to switch to using the QuTS hero operating system. QuTS hero provides benefits such as ZFS data integrity and WORM technology to prevent data tampering. (Switching to QuTS hero is supported starting from QTS 5.2.2.)
Using six 3.5-inch 22 TB hard drives in RAID 5 and two 2 TB M.2 SSDs. Hard drives and SSD sold separately.
-
2.5GbE is a must!
TS-664 is as fast as a single-port 10GbE NAS with up to 589 MB/s transfer speeds by setting port trunking with the two built-in 2.5GbE (2.5G/1G/100M) ports.
-
Quad-core for multitasking
Perform additional tasks, stream more media, and have more services running with an Intel® quad-core processor optimized for multitasking.
-
Smooth video conversion
Built-in GPU for enhanced video conversion, allowing videos to be smoothly streamed from the NAS to mobile devices.
-
Upgrade to dual-port 10GbE
Futureproof your network connection by installing a PCIe dual-port 10GbE network card that delivers up to 1,644 MB/s transfer speed.
-
Faster USB transfer
Two USB 3.2 Gen 2 (10Gbps) ports allow faster backup to/from USB devices.
-
More M.2 NVMe SSDs
If two M.2 slots aren’t enough, install a QM2 PCIe expansion card for more M.2 SSD slots.
