QNAP TS-431U-US overview

  • 1Description

Equipped with business class features, the TS-431U 4-Bay SMB NAS Server from Qnap is a compact 4-bay NAS with a 1U rackmount form factor that is designed for file sharing, backup, synchronization, remote access, and more within SMB environments. It is compatible with Windows, Mac, Linux, and UNIX and runs the QTS 4.1 operating system. It is also well suited for the creation and use of a personal cloud so you are able to access your data from virtually anywhere. Using services such as DLNA, AirPlay, and more it is possible to stream your multimedia library. The TS-431U is also able to perform on-the-fly and offline video transcoding, including Full HD 1920 x 1080 content.

The TS-431U is powered by a 1.2 GHz ARM Cortex-A9 Dual-Core processor which will allow you to run multiple functions simultaneously. The built-in 1GB of DDR3 RAM will allow quick access to frequently-used files and programs, and network connectivity is achieved via the dual Gigabit Ethernet ports. The dual Gigabit Ethernet ports also support link aggregation to help increase the total data transmission capability, as well as failover and dual IP to help ensure continuous system operations.

The 4-bay enclosure has the ability to natively house both 3.5" or 2.5" SATA III and SATA II hard drives or SSD drives. To support both drive formats, screws are included to accommodate both drive sizes. Read and write speed of the TS-431U can reach up to 148 MB/s and 119 MB/s respectively, and data transfer speeds with AES 256-bit encryption can reach over 33 MB/s.

The TS-431U operates on 100-240 VAC and includes 2x Ethernet cables, 12x 2.5" HDD flat head screws, 16x 3.5" HDD flat head screws, a power cord, and a hard disk tray key.

Equipped with a powerful yet energy efficient 1.2 GHz Freescale ARM Cortex-A9 Dual-Core processor, the TS-431U is a high-performance NAS for small and home offices, providing performance of up to 148 MB/s read and 119 MB/s write throughput. The TS-431U's encryption and decryption performance provide transfer speeds of over 33 MB/s with AES-256 bit full NAS volume encryption, boosting system performance and security while ensuring the safety of sensitive personal data stored in the TS-431
Efficiency and Dual LAN Support
The TS-431U supports multiple port-trunking modes, enabling IT administrators to set up link aggregation to increase total data transmission capability. Failover and dual IP are also supported to ensure continuous system operations.
