Network Storage Enclosure enables you to add disk storage on the network to share documents, files, and digital media such as music, videos and photos. With 4 bays, this storage enclosure is ideal for server deployment in office settings, allowing businesses to flexibly add up to four internal SATA drives on a per- need basis to fulfil storage requirements as they grow. Remote access to files from the Internet is also possible with the built-in FTP server. With this FTP feature, company employees can access work files via the Internet while outside the office.

Raid Configuration RAID, short for Redundant Array of Independent Disks, is a combination of two or more disks with the aim of providing fault tolerance and improving performance. There are several different levels of RAID, with each one providing a different method of sharing or distributing data among the drives. JBOD RAID 0 RAID 1 RAID 5

Raid 0 - Striping "Striped set without parity" or "Striping". Provides improved performance and additional storage but no redundancy or fault tolerance. Any disk failure destroys the array, which becomes more likely with more disks in the array. A single disk failure destroys the entire array because when data is written to a RAID 0 drive, the data is broken into fragments. The number of fragments is dictated by the number of disks in the array. The fragments are written to their respective disks simultaneously on the same sector. This allows smaller sections of the entire chunk of data to be read off the drive in parallel, increasing bandwidth. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss.

Raid 1 - Mirror A RAID 1 creates an exact copy (or mirror) of a set of data on two or more disks. This is useful when read performance or reliability are more important than data storage capacity. Such an array can only be as big as the smallest member disk. A classic RAID 1 mirrored pair contains two disks (see diagram), which increases reliability geometrically over a single disk. Since each member contains a complete copy of the data, and can be addressed independently, ordinary wear-and-tear reliability is raised by the power of the number of self-contained copies

RAID 5 provides data striping with distributed parity, which stores information that can be used to reconstruct data. A RAID 5 array will be the size of all the combined disks capacity less the capacity of one disk, e.g. If there are 4x 80GB disks in the array, the arrays capacity will be 240GB (3x80GB). Implementing RAID 5 on the DNS-343 allows it to continue operating even if one of the disks fails. The diagram below indicates the operation of RAID 5. Raid 5 - data striping with distributed parity

BOD (for "just a bunch of disks," or sometimes "just a bunch of drives") is a derogatory term - the official term is "spanning" - used to refer to a computer's hard disks that haven't been configured according to the RAID (for "redundant array of independent disks") system to increase fault tolerance and improve data access performance.
