The ReadyNAS also has some additional features such as being able to function as a print server, host USB external drives, and stream media files directly to other devices without going through a computer. With 4 500 GB disks, the ReadyNAS now gives 1.5 TB of disk space, again with one disk failure.With 3 500 GB disks, the ReadyNAS switches to RAID 5 leaving you with 1000GB or 1TB of available space and the ability to tolerate one disk failure.With 2 500 GB disks, the total space available is still only 500GB, but the data is now mirrored so that one drive can fail without affecting operations.With 1 500 GB disk, the total space available is 500GB but there is no redundancy so if your disk fails all data is lost.As the name suggests, with X-RAID you can start the NAS with just a single drive and add additional disks at a later time to increase capacity. The ReadyNAS NV comes with a proprietary implementation of RAID that Infrant calls X-RAID for expandable raid. The ReadyNAS has four removable disk trays for SATA drives and on the back of the device there is a large fan. ![]() It comes in a steel gray finish with a perforated front grill. Physically, the ReadyNAS is compact unit and measures 8″H x 5″W x 9″D. Generally, most RAID setups allow at least one disk failure without affecting the original data. ![]() In a RAID setup, the data is spread across multiple drives along with some extra information to provide fault tolerance. The ReadyNAS is also a RAID device, which stands for Redundant Array of Inexpensive Disks. ![]() Basically, the ReadyNAS is a small box with several hard-drives that you can access through the network without needing a dedicated computer to serve the files. The ReadyNAS NV is a network attached storage (NAS) device produced by Infrant.
