Question Help for a noob ref M.2 RAID 0

[Wizerbwski]

Hi guys,

Just a quick question.

I have x2 1TB M.2 drives (Kingston KC300)

I havent built my system yet. My question is, is it worth putting these drives in RAID 0 on this motherboard:
https://www.overclockers.co.uk/msi-mpg-z790-carbon-wifi-lga-1700-ddr5-atx-motherboard-mb-36v-ms.html
CPU will be a 13900K when released.

I dont want to loose x8 lanes on my GPU, will adding these two drives to the CPU bus cause this? Is it better to add them onto the chipset lanes (will that array be then bootable?)

Im at a loss as to weather to stick to 2 separate drives or try and RAID them and not really understanding the consequences.

Thanks in advance.

KC300 or KC3000 ?

Anyway - not worth to raid them. 2 separate drives is better.

Sorry, KC3000

Or do I just go with AMD's newer AM5 architecture?

I don't think you'll get much, if any, love for RAID 0 here.....particularly with SSDs.

The best way to do RAID 0 with SSDs is to not do it at all.

What do you hope to get out of this config?

You will get:
great benchmark numbers
zero user facing difference
greater fail potential

Short answer... don't do it.

Ok, thats why I came to the experts here. I wont do it, I simply thought it would yield faster read and write speeds thats all.

Longer answer:
Raid-0 has been over hyped as a performance enhancer.
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 we 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.

Here is a older study using ssd devices in raid-0.

Spoiler... no benefit at all.
