# Helios64 Introduction.
Helios64 is a powerful ARM board specially designed for Network Attached Storage (NAS). It harnesses its processing capabilities from the **Rockchip RK3399 SoC**.
Helios64 is our latest design for the ultimate ARM powered NAS. Compared to the [Helios4](/helios4/intro/), it offers improvement on every single key aspect :
* More storage capacity with 5x SATA ports,
* Greater network throughput with Multi-Gigabit Ethernet (2.5 GbE),
* Faster and Larger Memory with 4GB LPDDR4,
* More functionalities with Display Port and DAS modes support,
* Reinforced reliability with Built-in UPS.
