I got a Dell R610 where I tried to put some SSD’s in, but the raid controller in it didn’t work that well with them.
Instead I decided to just use two 15k rpm SAS disks, and then have them in raid 0 to give me both some performance and capacity.
The data on the raid 0 is just some temp. data, which is only on the raid0 because it is a bit faster to work with there, compared to the 5400 rpm disk it came from. The worst thing happening if the raid0 loses all its data, is that the server has to copy the data over again from the slow disk, and then it will continue to work as before.
Still I am told raid 0 is stupid to use, and I should use ssd. I can’t get an answer to why I should not use raid 0, when I don’t really care about the data on it. I could understand it if it was important data, but this isnt.
So does anyone here have a reason to why it is bad to use raid 0 to get some more performance and capacity out of two disks, while the data on it can be lost without any issue?
