About TerraMaster F4-423
The TerraMaster F4-423 operates on an Intel Celeron N5105/N5095 quad-core processor built on Jasper Lake architecture with x86 64-bit support. The processor runs at 2.0 GHz base frequency and reaches 2.9 GHz turbo speed, delivering 50% improvement in high-load workflows, 37% faster file retrieval, 35% better database response time, and 40% faster PHP webpage responses compared to previous generation models.
The device ships with 4 GB DDR4 dual-channel memory operating at 2133 MHz supplied as a single SODIMM module. Two SO-DIMM slots allow memory expansion up to 32 GB maximum capacity, though Intel specifications for the N5105/N5095 processor officially support 16 GB across two channels.
Storage architecture includes four SATA drive bays accommodating both 3.5-inch and 2.5-inch SATA hard drives plus 2.5-inch SATA SSDs. Maximum internal raw capacity reaches 80 TB using four 20 TB drives. The system incorporates two M.2 2280 NVMe SSD slots for cache acceleration or primary storage.
Key advantages include:
- Intel UHD Graphics with hardware transcoding for H.264, H.265, MPEG-4, VC-1 codecs at 4K 60 FPS
- Dual 2.5 GbE Ethernet ports with Link Aggregation reaching 5 Gbps combined bandwidth
- Comprehensive RAID support (0, 1, 5, 6, 10, JBOD, single disk, TRAID)
- AES-NI hardware encryption engine
- Two USB 3.2 Gen 2 ports and HDMI output
The F4-423 measures 227 x 225 x 136 mm and weighs 3.6 kg. The aluminum-alloy chassis with plastic panels houses an intelligent temperature control system featuring a silent fan. The compact design supports both vertical and horizontal placement configurations.
TOS operating system provides Linux-based functionality supporting file storage, mail servers, web servers, FTP servers, MySQL databases, CRM systems, Node.js, and Java virtual machines. The system handles 4K video decoding with uPnP/DLNA protocol compatibility and offers multiple backup solutions including Centralized Backup, Duple Backup, Snapshot, and CloudSync.
