[SOLVED] What is a RAID Setup?

[Iver Hicarte]

Good day,

As the title says, what is a RAID setup when it comes to storage configuration, I have been reading a lot of about this online but I just can't seem to understand the techy gobbledygook, can someone please provide an answer in "English"? An answer that can be easily understood and at the same time can help me understand the concepts related to this topic?

Most people don't need RAID, and it depends on what sort of drives you are using as to if you see any benefits. HDD might be faster, NVME not at all.

I use dummies guides, not as an insult to you, but as they use simple terms for most part.

OMG. search for Beginners guide to raid and all you get are guides for that dumb mobile "game"

Redundant Array of Independent (or Inexpensive) Disks.

A means of 'combining' 2 or more physical drives to serve some function.

There are various types of RAID arrays.

For 99% of consumers, none of them are any use, and often make things worse.

Thanks for this, I read the 2 articles, I get the concept but still not the whole picture, lol. But I did get a bit of knowledge out of it and have more of an understanding.

Its not really needed for most of us. Why are you looking? Just to know what it is or use it?

2 main types used , one is for backups and the other is for capacity/speed (there are more types but 2 mainly used, I don't use it so I am not going to try to explain the others, and get them wrong.).

I keep it simple and only use 2 drives in example
One type of RAID duplicates the information onto both drivers, so you lose capacity but have a backup - If 1 drive dies, you can still recreate array based on 1 drive so you don't lose anything.
Other type of RAID combines both drives to make PC think its one big drive, and means if you use HDD the write speed is more than if you use 1 drive, same applies to read speed. - Gain speed but if one drive dies, you lose everything

if you use nvme, you don't gain any speed using RAID, as PCIe already running as fast as it can. There is really no use to RAID being on consumer motherboards, its just an extra thing mb makers can charge people for.
