TS-435XeU
4-bay, short-depth rackmount NAS supporting 2.5GbE/10GbE connectivity and M.2 NVMe SSD caching

The compact and feature-rich TS-435XeU offers a professional quad-core NAS solution in a short-depth rackmount form factor. Native 10GbE SFP+ and 2.5GbE connectivity, along with M.2 NVMe SSD slots enabling cache acceleration, allows businesses to efficiently handle everyday tasks such as file backup/restore and promote team collaboration through increased productivity. The space-saving, short-depth design makes the TS-435XeU easy to install in small media cabinets or locations with heavy cabling. Supporting numerous business applications (including file sharing and synchronization, snapshot protection, containerization, cloud storage gateways, and video streaming), expandable storage capacity, and install-on-demand apps, the TS-435XeU is an ideal, cost-effective entry-level rackmount NAS.

Less space required for greater possibilities
Compared to a traditional 4-bay rackmount NAS, the compact TS-435XeU has a depth of just 292 mm. This makes the TS-435XeU an excellent choice for smaller racks, and the unused space can be reserved for cabling or ventilation. The TS-435XeU is space-saving for flexible deployment and is particularly suitable for multiple locations and applications such as offices, audiovisual environments, and security surveillance recordings.
