Hi!<br />
<br />
It depends on which array are you using:<br />
RAID 0 or striped set - fast, but not reliable.<br />
RAID 1 or mirror set - reliable, but does not improve performance significantly<br />
RAID 5 or striped set with parity - fast(er) and reliable<br />
Use combinations RAID 0+1, 1+0, 5+0, 5+1 for enhanced performance and reliability.<br />
<br />

RAID array for network server question

what vital function does the RAID array provide for network server,  is it connectivity, data protection, fast data sharing, or reliability (leaning towards this one).

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.
