Description
QNAP Short depth 1U rackmount 4-bay NAS M.2 NVMe SSD caching with 4GB RAM (QN-TS-435XeU-4G)Â (3 Years Manufacture Local Warranty In Singapore)-EOL
Short depth rackmount 4-bay NAS, supporting 2.5GbE 10GbE connectivity and M.2 NVMe SSD caching
Features
The compact and feature-rich TS-435XeU provides a professional-grade quad-core NAS solution in short depth rackmount form factor. The native 10GbE SFP+ and 2.5GbE connectivity alongside M.2 NVMe SSD slots that enable cache acceleration allows businesses to efficiently tackle everyday tasks like file backup restore and to boost team collaboration with higher productivity. The space-efficient short depth design makes the TS-435XeU easy to install in small media cabinets or places with a lot of cabling. Supporting abundant business applications (including file sharing and sync, 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.

Features
The compact and feature-rich TS-435XeU provides a professional-grade quad-core NAS solution in short depth rackmount form factor. The native 10GbE SFP+ and 2.5GbE connectivity alongside M.2 NVMe SSD slots that enable cache acceleration allows businesses to efficiently tackle everyday tasks like file backup restore and to boost team collaboration with higher productivity. The space-efficient short depth design makes the TS-435XeU easy to install in small media cabinets or places with a lot of cabling. Supporting abundant business applications (including file sharing and sync, 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.

RAID Group
 To ensure data security, system stability, and storage performance, the maximum number of drives for a single RAID group is now 16 (applicable to RAID 5, RAID 6, RAID TP, and subgroups of RAID 50 and RAID 60). Nevertheless, users can combine multiple RAID groups into a large storage pool that contains more than 16 drives, using RAID 50, RAID 60, or RAID 10 as the RAID configuration. This enhancement will only be applied to new RAID groups. All existing RAID groups and storage systems will not be affected.

RAID Group  To ensure data security, system stability, and storage performance, the maximum number of drives for a single RAID group is now 16 (applicable to RAID 5, RAID 6, RAID TP, and subgroups of RAID 50 and RAID 60). Nevertheless, users can combine multiple RAID groups into a large storage pool that contains more than 16 drives, using RAID 50, RAID 60, or RAID 10 as the RAID configuration. This enhancement will only be applied to new RAID groups. All existing RAID groups and storage systems will not be affected.
