. QNAP TS-464 4-Bay NAS Enclosure The QNAP TS-464 4-Bay NAS device is a compact NAS with superior performance. Supporting up to 66TB storage and 4TB M.2 SSD caching the TS-464 fulfils your multitasking challenges for file management backup collaboration and video conversion.Key Features . CapacityUn-populated four (4) bay network attached NAS storage device. 2.5GbE connectivityThe TS-464 is as fast as a single-port 10GbE NAS with up to 589 MB/s transfer speeds by setting port trunking with the two (2) built-in 2.5GbE (2.5G/1G/100M) ports. Quad-core for multitaskingPerform additional tasks stream more media and have more services running with an Intel quad-core processor optimised for multitasking. Smooth video conversionBuilt-in GPU for enhanced video conversion allowing videos to be smoothly streamed from the NAS to mobile devices. Encryption EngineFeatures Intel AES-NI 256 hardware-accelerated encryption to boost system performance while securing sensitive data. Upgrade to dual-port 10GbEFuture-proof your network connection by installing a PCIe dual-port 10GbE network card (sold separately) that delivers up to 1647 MB/s transfer speed. Faster USB transferTwo (2) USB 3.2 Gen 2 (10Gbps) ports allow faster backup to/from USB devices. More M.2 NVMe SSDsIf two (2) M.2 slots aren’t enough install a QM2 PCIe expansion card for more M.2 SSD slots. 2.5GbE NAS is a mustWith increasing availability on switches motherboards and laptops 2023 is the year of 2.5GbE. The 2.5GbE TS-464 NAS is as fast as a single-port 10GbE NAS. By setting port trunking with the two (2) built-in 2.5GbE (2.5G/1G/100M) ports to unleash network potential and increase fault tolerance TS-464 delivers up to 589 MB/s transfer speeds.Upgrade to dual-port 10GbE with a PCIe network cardWith a superior hardware design you can install a dual-port 10GbE network card QXG-10G2TB (sold separately) in the TS-464. Combining 10GbE networking quad-core processor and M.2 SSD caching the TS-464 unleashes its full performance potential.Expand storage capacity up to 16 hard drivesThe TS-464 supports a storage capacity of up to 66TB by installing four (4) 3.5-inch 22TB hard drives (sold separately) in RAID 5. By connecting a TL-D1600S QNAP storage expansion unit (sold separately) you can add an additional twelve (12) hard drives to the TS-464 to achieve up to 280TB storage space to meet growing storage requirements.Accelerate AI–powered image recognition and caching with TPU and PCIe expansionThe TS-464 has two (2) M.2 PCIe Gen 3 slots for installing NVMe SSD (including Apacer Micron Seagate WD and more) or Edge TPU.Install M.2 NVMe SSDs for cache acceleration or efficient tiered storageIf you have a huge number of small files requiring read/write operations you can easily boost IOPS of the TS-464 by configuring its two M.2 SSDs as a cache disk. When transmitting bigger files you can create a storage pool with two M.2 SSDs. With Qtier automatically moving hot data to SSD and cold data to hard drives the TS-464 allows you to enjoy exceptional application performance.Accelerate AI–powered image recognition with TPUBy leveraging a Edge TPU to QNAP AI Core (the AI-powered engine for image recognition) the TS-464 can perform high-speed face and object recognition. Edge TPU enables QuMagie to quickly process thousands of photos with high-speed AI Image recognition and classification and QVR Face to analyse real-time video for instant facial recognition.Abundant I/O capabilities with PCIe expansionQNAP offers a wide range of expansion cards (sold separately) to add versatile functions to your NAS. The TS-464 has one (1) PCIe Gen 3 x2 slot that supports various expansion cards for expanding application potentialQM2 card (QM2-2P10G1TB) .  Add
