Will creating a basic disk partition with the remainder of my Raid 0 2TB disk slow the raid 0 down?

Rafael Mestdag · Jan 22, 2018

This is a picture of my Raid 0 disk in Disk Management which I made by joining a 500GB disk with a 2TB one(I know it's stupid!), the resulting disk is a 1TB Raid 0.

I would like to know if I can create a volume with the remaining space(1.4TB) and not slow my Raid 0 disk down.

Any help appreciated!

Can you?
Probably.

Will it slow the RAID down?
Maybe.

Try it and see. If it does, and the resulting performance is unacceptable, undo it.

But why would you do a RAID 0 with those 2 drives in the first place?

I did it because of the two 2TB disks I have one is starting to fail, so I decided to use it with the 500GB one to create a Raid 0 disk for my games. But I do back them all up onto my other new 2TB disk regularly.

With 2 drives in raid-0, you have doubled your opportunity for failure.

If you are worried about failure, using the two 1tb drives in raid-1 would give you redundancy in case of a hard drive failure.

How important is the data that you have on your PC?
If you were to be hit with a fire that destroyed your pc could you recover whatever was essential/
What would you do if you were hit with ransomware encryption?

Best to have EXTERNAL backup for what you value .

From a performance point of view, raid-0 is a loser.
You only win synthetic benchmarks.
Sequential benchmarks do look wonderful, but the real world does not seem to deliver the indicated performance benefits for most
desktop users. The reason is, that sequential benchmarks are coded for maximum overlapped I/O rates.
It depends on reading a stripe of data simultaneously from each raid-0 member, and that is rarely what apps do.
The OS does mostly small random reads and writes, so raid-0 is of little use there.
In fact, if your block of data were to be spanned on two drives, random times would be greater.
There are some apps that will benefit. They are characterized by reading large files in a sequential overlapped manner.

I've noticed a significant performance improvement in games loading times, I don't really understand the theory behing Raid in general but I do know what I can notice in the real world, and I've noticed a real decrease in most of my games loading times.

As for backup, I am constantly backing up the 1TB Raid 0 disk onto my 2TB Seagate internal disk. I know it would be best to have an external 2TB drive for that, but the chances of a fire or even a really bad virus that would take out all of my data are almost zero.

I've never had either of those catastrophes happen to me. The only time I've lost all of my data was once(recently actually) I accidentally deleted all my disks while installing Windows 10.

Besides, all I'm actually keeping on the Raid 0 disk are my games, which like I said, I am constantly backing up onto my new 2TB disk.
