Hey all and squeaks to you.

 

I've been out of the tech loop for a long time (built last pc when I was working at EVGA in the 200 series days) now toying with my rog advantage edition g15 laptop

 

Anyway...

 

With the advent of m.2 integration my little mouse brain has been working on ideas to break my pc in new and hilarious ways and I've settled on something fun. 

 

I have 2 nvme drives. If I partition each in half can I run raid 0 on the primary partitions of each and mirror to the secondary partitions? 

 

I haven't tried it yet, just having thoughts. 

 

Back in the pre solid state days, latency would be an immediate road block to doing so with any hope of stability.  

 

Maybe I'm talking absolute nonsense maybe it has already been done . "Just google it" now brings sadness for all things that aren't buying sponsored garbage and hot lists . So I turn to the mighty ltt community in my timid return to forum culture.

Can I ask what your hoping to achieve with this arrangement?

I might be experienced, but I'm human and I do make mistakes. Trust but Verify! I edit my messages after sending them alot, please refresh before posting your reply. Please try to be clear and specific, you'll get a better answer. Please remember to mark solutions once you have the information you need. Expand this signature for common PC building advice, a short bio and a list of my components.

 

Common build advice:

1) Buy the cheapest (well reviewed) motherboard that has the features you need. Paying more typically only gets you features you won’t use. 2) only get as much RAM as you need, getting more won’t (typically) make your PC faster. 3) While I recommend getting an NVMe drive, you don’t need to splurge for an expensive drive with DRam cache, DRamless drives are fine for gamers. 4) paying for looks is fine, just don’t break the bank. 5) Tower coolers are usually good enough, unless you go top tier Intel or plan on OCing. 6) OCing is a dead meme, you probably shouldn’t bother. 7) "Bottlenecks" rarely matter and "Future-proofing" is a myth. 8) AIOs don't noticeably improve performance past 240mm and don't improve at all past 360mm. 9) RTFM.

He/Him - I'm a PhD student working in the fields of reinforcement learning and traffic control. PCs are one of my hobbies and I've built many PCs and performed upgrades on a few laptops (for myself, friends and family).

Honestly, experience.  I expect that there will be complications. Alot can be learned in how it would function first hand and if there is any appreciable boost in performance and what the trade offs will actually be. It's not a primary machine so data loss if it's unstable isn't an issue.

I suggest you change title to something more descriptive. This is hardly newbie question as it taps to limitations of technology.

 

I'm not quite sure how you have thought this through. Partition each drive to 2, have Vol0s in RAID0 for performance and Vol1s mirror of each other? Or each mirror for the RAID0? Latter AFAIK shouldn't work. Mirroring would need to have equal sized partitions on earth side, and in RAID0 it's seen as total capacity of the two. I guess you could have 2xRAID0s across two drives with software backup. But when the backup writing is in progress, that will have effect on performance. You are still limited to each drives max r/w speeds, regardless of how the setup is done.

 

Someone else will correct me if that's not correctly thought.

My apologies.  I'm a newbie in the sense that I dropped pc building well over 15 years ago and haven't followed tech closely so honestly I am basically a newbie. I do see how hat can be misleading,  it was not my intention. 

 

 

To the design, it's unconventional yes but I can apply what I learn to new ideas. I'd like to do the following 

 

1. Split 2 m.2 drives into 4 total equal volumes (both 970 Evo 1tb drives)

 

2. Set up raid 0+1 

  - raid 0 would be split between the two separate drives onto their respective primary partitions 

- raid 1 would mirror the data within the drive to it's partition on that same drive. Only that drives  half of the data would be copied onto the partition 

 

2a. (Secondary experiment)Mirror the complete data to each partition.  Creating 2 redundant copies. 

 

Currently I want to see how it affects performance but mostly I want to see if it can work and what if anything is the weakest link as applied. 

 

Software raid is undeniably unstable.  But I'd really like to play with the result. 

 

I really loved messing with possibilities but work got in my way 🙂

This will not work. Any drive can only have one raid set up at the time. So since partition 1 already has raid0, it can't have raid1 also. Meaning that it would need to have software backup to secure data.
