I have a hard drive setup currently on my computer is setup in raid 4. I was wondering can it be changed from raid 4 to a non raid setup or is it permanently in this configuration. The computer I have is a gt73vr sli212. I was just curious because I would like better drive performace. According to a few threads I've seen raid 4 has poor write speeds. Thanks for the help in advance. If you have any recommendations please feel free to add them.
Also it the raid 4 setup I belive is on a ssd setup. Does this make it fast?
I honestly know very little about hard drives so I may be missing a simple answer

RAID 4 has comparitively low write speeds as the parity data is all on one drive. RAID 5 is better as it spreads the load across all drives in the array. RAID 5 would also be a better for SSD's as the endurance on all drives will be hit equally, rather than hitting one drive constantly with parity.

It is still a relative term though - are you writing a large amount of data and noticing the slow writes?

The ability to change without wiping the drives and starting again will depend on the controller capabilities and how full the array is. Please remember that a RAID is not the same as a backup - you should have both if possible. In that case, there would be nothing to stop you flattening your RAID 4, creating a RAID 5 array and...
