RAID 0 Storage Size Increase

This has probably been answered multiple times but I have a question regarding RAID 0 in general.

Gigabyte 970a-ud3p
FX-4300
Two 60 GB Samsung SSD RAID 0 (Windows 10 Only)
Seagate Barracuda 1TB and WD 500GB Blue RAID 0 (Storage Only)

Looking to upgrade the WD 500GB to a Seagate Barracuda 1TB but keep the RAID functional and retain all data present within ongoing RAID.

How should I go about upgrading the old drive to the new drive and retain the data and RAID?

Can I just make a backup of the Storage RAID to a single drive, set up the new 2TB storage RAID, and then copy the data over somehow?

Thanks for the help everyone!! -Dane

You can't do that in place, with a RAID 0.

Copy the entirety of the data off to something else.
Swap the drives.
Rebuild the RAID 0.
Copy the data back.


And a RAID 0 should never be run without a strong backup routine.

How would I go transferring the data back? Cloning? I thought about turning the WD 500GB into a parity drive but I'm not familiar with storage size requirements required for the parity drive nor which RAID # to choose. I chose RAID 0 for the slight performance boost; can you get a performance boost and have a parity drive?

No, NOT cloning. That would probably carry aspects of the original RAID info.
Copy JUST the data to something else.

Parity drive? That has nothing to do with a RAID 0.
Perhaps you're thinking of a RAID 5. That won't work either.
1TB + 1TB + 500GB + RAID 5 does not work.

IMHO, RAID 0 has little use in the consumer space.
Especially with SSD's...your OS drive.

Yeah that seems to be what I'm finding out reading around...I know that RAID 0 is a bit dangerous in terms of data retention/redundancy it was suggested for a bit of a boost in read and write times.
RAID is new to me and just experimenting....how would you get two storage drives together into a RAID and then make them easily swappable if one dies?

IN a RAID 0, there is no "swapping". If one dies or is removed, that's it.
All data in the entire RAID array is gone. There is zero redundancy in a RAID 0.

RAID 0 can boost the speed of HDD's.
But not SSD's. http://www.tomshardware.com/reviews/ssd-raid-benchmark,3485.html

In most consumer level uses, RAID 0 is not really beneficial at all. Certainly not enough to warrant the maintenance hassle and risk of data loss.

My main system has 5 drives. No RAID in existence.
My NAS box is a RAID 5 (4 x 4TB HDD), but that's dedicated hardware and software.
