Synology Ds415+

Powerful 4-bay NAS for compute-intensive applications and encryption. Equipped with an Intel Atom 2.4 GHz quad-core processor, including an AES-NI hardware encryption engine and floating-point unit. 2 GB DDR3 RAM. USB 3.0, USB 2.0, and eSATA ports as well as dual LAN ports. Storage capacity of up to 24 TB.

Conclusion from computerbase.de, 09.2014: "The great strength of the DS415+ is the speed of AES-256 encryption. No other NAS in the test field encrypts data faster while also providing reserves for link aggregation usage. This is precisely the area for which Intel's C2000 processor series is designed, and it excels in this regard.".
