BIG Raid 0 setup

[Giuseppe96]

Hi everyone, I will setup on my home server a Raid 0 of 4TB (500GB + 500GB + 1 TB + 2 TB and eventually other 80GB) but when I start the setup and enter in the utility i read that the maximum capacity is about 380 GB. 

And booting up the system, because actually I had a Raid 1 500GB and i deleted this raid but now i can't see the other disks running windows, but i can see that in the bios.

Can anyone help me?

Your data is going to die faster than a lemming going off a cliff

also I'm pretty sure you want at least the same capacity drives for RAID 0, better yet the same cards, although there's no reason for you to do RAID 0 I would think

As for the second part, check your disk manager in windows, otherwise use Gparted or something to reformat your hard drives.

why are you even trying to do something like that...

the speeds are going to be bad and the reliability is going to go down the drain

you should just sell those drives on craigslist and buy one good hard drive which will be faster and safer than this ghetto setup

You cannot have a RAID with different sized disks. Not unless you do some multi level raid insanity. Basically you would have to have a RAID 0 for the 2 500GB drives, and then RAID 0 that with the 1x 1TB drive. Then finally RAID 0 the 2 2TB systems.

The RAID 1 is probably just not showing up in explorer, you will probably see the disks in disk-management. You can open disk management like this.

1. open control panel, type "disk" into the search bar. 2. select "create and format hard disk partitions".

I really hope you don't have anything important on that RAID 0 array.

Doing this 3 Raid 0 I should have a 4 TB disk space?

I've founded those HDD in my garage in old computer, but i don't think anyone would buy very old HDD, maybe in the next 3-4 months i'll go to buy other storage maybe a 100TB-NAS

No, it would just not work. I was basically joking, you can only achieve that kind of RAID with some servers, if even at all.

You simply cannot RAID different sized disks period.

EDIT: Multiple level raids can be done AFAIK, but I am certain that the parts that are going to get "merged" need to be identical. Go to the wiki page for RAID, it has pictures that represent what I am talking about.

If you were to try. You would need more drives to be able to do it, 500GB drives in a combined ~1TB RAID, would only work in RAID with another similar setup.

nono, i have only the games that i download and put on this pc, I have all of my important data in other part and have a daily backup on a network HDD :D

Using different size disks, is a Parity JBOD - you can do this in unRAID, but it would not be recommended with such a low ratio of space/disk in an array that small. You're asking for trouble. The raid would have a large chance of failing if the 2TB died.
