Wtf is Nas an Raid

[NeoSk11zle]

So wut is this wizardry, like raid 0,1,2,3,4... and what is nas?

Oh, and NAS stands for Network Attached Storage. It's a kind of server where you keep a mass storage "vault".

RAID is basically grouping multiple, at least 2, drives for different purposes.

Frequently used RAID modes are 0 and 1. 0 is striping and 1 is mirroring.

For further information check this out : https://en.wikipedia.org/wiki/Standard_RAID_levels

 

NAS is an abbreviated vocabulary of "Network Attached Storage". Its antonym is DAS, which stands for "Direct Attached Storage".

so like splitting the work. It should be like sli. lol

More like speed (RAID 0) and safty for your data (RAID 1)

Do you know what a SAN is?   LOL just kidding, that would be the most useless help ever! 

 

Raid is just a way of combining multiple disks in different configurations to achieve different things, such as mirroring both drives, or putting a stripe on two drives and letting each handle each of the work, etc etc.  If you were good at networking you could imagine it as disk protocols almost.  

 

a Nas is just a storage device that sits on the network, it is a client on the network as opposed to a SAN which is pretty much the whole center of the network. NAS = network attached storage.  SAN = Storage Area Network.

Linus has two techquickie videos about RAID. A NAS is a network-attached storage area.

The two most common types of RAID is RAID 0 and RAID 1. I'll repost a previous post of mine that explains them in a more simpler fashion:

Best analogy I've heard:

 

'RAID-0: 2 or more people sing alternate words in the song. This is faster because they can breathe, turn the page, etc. while they're waiting for their next turn. If one of them quits, the song will be ruined forever, though.

 

RAID-1: 2 or more people sing the song at the same time. If one of them quits, the song will still be sung because everyone else knows all the words, too. You can hire a new singer who will quickly learn the song from everyone else.'

 

Just remember RAID is not a backup.

 

TL;DR - RAID 0 = speed but increased chance of data loss (not increased chance of failure). RAID 1 = redundancy but no gain in performance and halved storage space (meaning that having two 1TB HDDs in RAID 1 will only give you 1TB total).

Hi there

 

The guys gave you excellent explanations and resources. My two cents here:

 

- A NAS stands for Network Attached Storage which is basically any storage device (HDD, Thumb Drive, etc.) that can be accessed over the network from another device. If you have a flash drive or an external drive connected to your router's USB port and configure it to be accessible from any device attached to that network (regardless if it's wireless or not) it can be considered a NAS. NAS devices are generally enclosures that fit one or more HDDs that can be connected to a router via a network cable and can be accessed by other devices on the network. One simple example would be the WD My Cloud. Such devices are often used to distribute and hold data that is accessed from more than one device (either from the internal network or over the internet), backup location of other devices or for media streaming. More advanced NAS devices can even hold specific applications that can serve and perform some tasks such as torrenting or hosting a media server such as PLEX. 

 

- RAID stands for Redundant Array of Independent/Inexpensive Disks and basically enables multiple drives to work as a single one in order to either achieve better performance, better redundancy (data safety) or a combination of both. The speed boost is achieved by splitting the data into multiple parts and writing those parts simultaneously to a number of drives at the same time. The redundancy is achieved by keeping copies of the data or parts of that data across multiple drives so in case one or more of the drives happen to fail for some reason (the number of failures depends on the specific RAID type) you can replace it and then safely rebuild all data and then have full access to it without suffering any data loss. Mind that RAID is by no means a replacement of a backup as it doesn't grant you safety against power failures, user mistakes, malware or physical damage. 

 

- There are two major RAID types: software and hardware and each of them has its own pros and cons. 

 

Let me know if you want more info on any of the RAID types, some specifics around NAS devices or simply more general info I'd be happy to provide it!
