Sony Vaio Z2 Possible Raid 0 Failure

After many years of service I have encountered what I believe is a Raid fail on my Sony Vaio Z2
The device BSOD'd twice today, first while watching a movie, second while verifying the raid using Intel RST

0x000000F4 (0x0000000000000003, 0xFFFFFA8009CA7B30, 0XFFFFFA8009CA7E10, 0XFFFFF80023D6F40)
0x0000007A (0xFFFFF8A004616D20, 0xFFFFFFFFC000000E, 0x0000000077A1ABC0, 0x0FFFFF88019590000)

During the Intel RST verification I suddenly got the message saying Disk on Port 0 unplugged and it gave me the BSOD, but not before showing 7772 Blocks with media errors

It appears Disk 0 is too damaged to continue

EDIT:
The original question was if I could swap one Disk in the raid without having to reconfigure

But as it turns out, the Z2 SSD Raid is in fact 2 on one board and can't be separated, I've only ever opened my Z1 and assumed it was 2 separate SSD's

Samsung MZRPA128HMCD-000SO I'll be looking into replacing this one part
Has anyone ever changed the Raid on a Z2 to simply be 2 Disks instead for less fail rate

 

I've already had the 256GB Gen2 SSDs fail on me twice ( http://forum.notebookreview.com/threads/vpc-z2-ssd-dying-or-mybe-virus.742260/ ), both times shortly after 2 years.
I haven't tried setting up the disks as JBOD, and I'm not sure it would help (e.g. if TRIM can be used in that case).
What I think is a good idea though, is to buy a larger SSD and keep it somewhat empty.

Whether that works for the Z2, I don't know.
