Secure NAS 2R5

The Secure NAS is a family of storage appliance from Addonics that combines the benefits of RAID storage, Network Attached Storage (NAS), Direct Attached Storage (DAS) and hardware AES 256-bit encryption all in a box. It is an ideal solution for storing a large volume of sensitive data, for securely transporting a large volume of data between different locations or for any application that requires protection against data theft.

The Secure NAS can be directly attached to any system via high-speed eSATA connection, this allows transferring a large volume of data quickly. The same data in the Secure NAS can be shared over a 1 Gigabit network. The entire RAID volume, including the boot sector and partition table, is encrypted. Data written onto or retrieved from the RAID is encrypted and decrypted on the fly by a high-performance FIPS certified AES 256-bit crypto engine.

The Secure NAS has also added new powerful features beginning 6/16/2014 via a new firmware release. There are now full disk sharing and existing folder sharing from drives created by other systems. Shares can be applied to both FTP and SMB for different users and with different READ/WRITE privileges. These new features allow quick set up of sharing information on existing drives through LAN and WAN, making it an ideal tool for setting up a private Cloud storage. It is also a great tool for sharing information on existing drive on a private network such as at home or a temporary LAN without any elaborate administrative setup.

The encryption is simple to operate. There is no software to run or password to enter. Simply insert a correct cipher key into the unit during the system start up, just like starting a car. Once the unit is powered up, the Cipher key can be removed. If the Secure NAS storage unit is stolen, the RAID volume will not be visible on the network or to any system. If the drives are taken out from the Secure NAS storage and directly attached to any system, the drives will appear as blank. There will be no trace of any recoverable data even examined by recovery software or surface scanning of the drive platter.


About this model

The Secure NAS 2R5, model SN1035E1G-S, accommodates up to ten (10) 3.5" SATA hard drives. The ten drives are set up as two RAID volumes for high performance and reliability. By using RAID 5 configuration, each RAID volume up to 16 TB can be created by using five 4TB hard drives. The entire RAID volume, encrypted by a FIPS certified AES 256-bit crypto engine, can be directly attached to any system via eSATA or used as a Network Attached Storage appliance on any 10/100/1000 network.

Additional USB drives, up to maximum fifteen (15) drive volumes when combines with USB hubs, can be shared over the network by attaching to the USB port on the back of the unit.

NetworkAttached Storage

  • Built-In SMB / Samba server for file sharing over LAN
  • Built-in FTP server for file access over the internet
  • Great for setting up a private Cloud storage or quick drive sharing
    • Support full disk sharing of drive with existing data in SMB and FTP
    • Support selecting existing folders1 that are already on the drive for sharing in SMB and FTP

  • Support 10/100/1000 Mbps network
  • Maximum data transfer over Gigabit LAN:

      RAID storage USB storage
    read write read write
    XFS up to 85 MB/sec up to 45 MB/sec up to 30 MB/sec up to 30 MB/sec
    EXT3 or EXT4 up to 50 MB/sec up to 35 MB/sec up to 30 MB/sec Up to 30 MB/sec
    NTFS up to 16 MB/sec up to 5 MB/sec up to 16 MB/sec up to 5 MB/sec
    FAT32 up to 18 MB/sec up to 8 MB/sec up to 18 MB/sec up to 8 MB/sec

  • Maximum partition size or drive volume capacity:
    • XFS - 16 TB
    • EXT3 - 16 TB
    • EXT4 - 16 TB

  • Maximum user accounts:
    • Samba server - 64,0000*
  • Maximum # of concurrent connections:

  • OS independent - can be used on any system
  • Cipher key

    There is no backdoor for the Secure NAS if the Cipher key is lost or stolen. To ensure there is a spare key, every Secure NAS comes with one pair of Cipher keys. One of these keys should be kept in a safe, secure location and, if needed, can be sent back to Addonics for duplicating additional keys. If one of the two keys is lost, be sure to make a back up of all the data stored inside the Secure NAS prior to sending your last Cipher key to Addonics. Addonics is not responsible for keys lost in the mail or the retrieval of the data inside the Secure NAS. Customers may also order additional Cipher keys with the same key code when ordering the Secure NAS.

    The AES 256-bit Cipher key used for the Secure NAS is the same Cipher key used in the Addonics Diamond Cipher drive kit, Ruby Cipher drive kit or the CipherChain. As a result, the same Cipher key can operate the storage device that has been encrypted by either the CipherChain, Diamond Cipher, or Ruby Cipher drive kit. The Cipher keys can also be reprogrammed with other codes by using the optional Cipher key programming system (model: ASWRNGSYS) or by sending the keys to Addonics for the reprogramming service (at no charge).

    There are two pairs of Cipher keys in this model. By default, these Cipher keys are all coded the same. You may request to two different codes at the time of purchase or leave a note in the instruction box at the final check on our online store
