NAS 4.0 Adapter
 
Share as many as 16 hard drives over the LAN      As large as one exbibyte per drive volume
75MB/sec transfer speed over 1G network       Enterprise NAS at a fraction of the cost
 
The NAS 4.0 is Addonics' 4th generation NAS adapter with several major enhancements. Comes with two eSATAp ports that allows attaching either two eSATA or two USB 2.0 storage devices onto the LAN, as many as 16 storages devices (or drive volume) can be attached to the new NAS 4.0 using USB hubs. With these many drives, you can easily share multi-Terabyte storage over LAN or build your own private cloud storage that can be accessed via the built-in FTP server.
 
Performance of the NAS 4.0 is quadrupled from the previous NAS adapter to 75 MB/sec over 1G network.Both the maximum number of SMB and FTP accounts as well as the concurrent users supported by the NAS 4.0 are vastly expanded to support over thousands and hundreds respectively.
 
The NAS 4.0 also support storage devices with multiple partitions, with each partition appearing as a share folder on the network. The supported file system now includes XFS, EXT2, EXT3, EXT4. NTFS and FAT32. A very large storage in excess of hundreds or thousands of Terabytes storage capacity can be easily built by attaching multiple units of Addonics RAID Towers or RAID Racks. A storage farm with capacity exceeding many commercial data center can be easily put together at just a fraction of the cost of an enterprise storage system. Storage capacity can be added to the NAS 4.0 in many many years to come without ever reaching the capacity limitation.
 
Constructed in a rugged metallic housing in the size of a cigarette pack, the NAS 4.0 adapter is built to last and can be deployed in home, general office, factory or mobile environment.
