What is RAID?

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 providing a different

method of sharing or distributing data amongst the drives. The DNS-321 supports RAID levels 0 and 1.

RAID 0

RAID 0 provides

data striping

, which spreads

out blocks of data over both drives, but does not

provide data redundancy.

Although performance is improved, the lack of

fault tolerance means that if one drive fails, all

data in the array will be lost.

RAID 0

RAID 1

RAID 1 provides

mirroring

over both disks, with

the same read/write speed of a single disk.

A

RAID 1 array can only be as large as it’s smallest

member disk.

Because the data is stored on both disks,

RAID 1 provides fault tolerance and protection,

in addition to performance advantages.

purchased (www.whateveryournameis.com) with your dynamically assigned IP address. Most broadband Internet

Service Providers assign dynamic (changing) IP addresses. Using a DDNS service provider, your friends can enter

your domain name to connect to your server regardless your IP address.
