Is RAID 0 Safe?

Go to solution Solved by Senzelian,

I wanted to setup the new WD Blue HDD (1 tb) I got in RAID 0 with my other, identical, drive. While researching, I watched an older video and Linus said that this solution is unreliable. Is it actually going to make me more susceptible to hard drive failure or was he just referring to less reliable than RAID 1? Is it less safe than just sticking with my one drive or will it be no difference?

In a RAID 0 config the data will be written across both drives. So if one of them fails, the data on the second drive will also be lost.

If you use both drives independently from each other and one fails, the data on the other one will still be usable.

That is what makes a RAID 0 twice as insecure as a normal setup. A RAID 1 will make the data twice as secure.

RAID 0 < no RAID < RAID 1

 

I had a RAID 0 with two 1TB Toshiba HDDs. It wasn't worth the trouble, cause I didn't notice any performance increase, even tho I was able to messure it.

It's not very safe i.e. if one drive fails then your in trouble. It trades redundancy for speed.

The problem with RAID 0 is that if one drive fails, all your data is now corrupt.

Oh ok. So is there an alternative to Raid 0 where I can use all 2 tb (separated is fine)? Because when I plugged it all in and booted my computer didn't recognize the other drive in file manager. I went into device manager and the drive was there.

You need to format the drive in order to use it.
