I have an MSI laptop, GT72s dominator. It has 2 m.2 sata ssd's that are capable of being configured in raid-0. Each is only 128 GB in size. Actually, the PC seller was supposed to do this before shipping it to me a few years ago. They made a mistake and did not do it. I am trying to decide if it is worth setting up now.

Given that the laptop already has a fast NVMe m.2 ssd used as the boot drive, it seems like overkill. The sata m.2 ssd's are pretty fast already for other uses. Anyway, I don't have any experience working with raid setups and so was hoping to get thoughts from people more knowledgable on the subject.
 
Real world? Yes tiniest bit faster to me. Worth the hassle? Would I do it again?
Probably a dedicated storage card with more reliability and raid5 or better. As it is... Wouldn't bother again with software raid 0 ssd. Risk/benefit isn't there.
 
It's useful if you want the sequential performance (writing to/from the NVMe), otherwise you have to hit rather high queue depths where a NVMe drive would be superior.
 
You’ll double your chance of data loss for no appreciable real world benefit in 99% of use cases.
 
Not worth it unless you get off running benchmarks or have heavy io work loads. Normal day to day stuff you won't notice a difference.
 
Laptop?

Unless you mirror them purely for safety reasons.. You are wasting resources. Sure, you got bragging rights, and smidge higher score in some bench mark app.. but real world? You'll never notice the difference. Better off having 2 volumes for your data.
 
Had a customer drop a setup like this in on me. He said it was SSD based and used it for project work. The machine had got corrupted and wouldn't boot.

Okay no problem I can get the mSATA SSD out and read the data off it and then rebuild it. Cool he said.

I open it up and find two mSATA drives in it. Turns out the idiot manufacturers shipped the machine out in RAID0 as standard.

There were tears.

Just not worth it in my experience.
