Raid 0 info

[LorenzoBrizzi]

Hello everyone I've a pc and I wanna know how to make it raid 0. I already know how to do it but only starting with new hard drives and not with a new and one with all my stuff over it. And I also wanna ask if I need same memory then the other ssd and the same model. thanks everyone!!

I have no idea whet you mean, can you try to be more explicit as to what it is that you want us to help you with?

raid 0 is a system where two or more identical drives are used in tandem to increase speed, and to add up their size.

 

writes are spread over the drives equally, for ex. if you write 5 sectors worth of data to a 3-drive raid 0 it'll write the first sector worth to the first drive, the 2nd to the 2nd drive, the 3rd to the third drive, then the 4th back to the first drive, and the 5th to the second.

 

then the next write will happen to the 3rd drive so load is spread equally.

 

 

theres one obvious issue with raid0: since all data is spread over all drives, if one drive dies, all the data is gone.

why is this worse than having one drive you may ask?

i'll explain:

 

imagine every drive you get has 1% chance of dying. (this is a BAD way of putting it, but it makes explaining easy, so hang on)

 

one drive: 1% chance of RIP data.

two drives: 1% chance the first drive dies, 1% chance the second drive dies -> 2% chance of RIP data.

three drives: we continue this, meaning 3% chance of RIP data.

and so on...

 

EDIT: i should also mention making a RAID also requires you to reformat the drives, meaning you'll lose the data already on the drive.
