Can i RAID M.2?

https://www.amazon.com/Samsung-950-P...p_89%3ASamsung

https://www.amazon.com/TUF-Z370-PRO-...700k+processor

ok so my question is can I take two of these 950 M.2 SSD's, connect them to this motherboard, and create a performance 0 array between them?

I assume you talking about a hardware array. Just check if the motherboard supports raid for NVME it either says it does or not.

If not you can use software array. But you will need to use a different drive to boot if that is the case,

Also keep in mind that all the RAID 0 in the world will not increase your random I/O. The only benefit is sequential reads and writes.

https://www.asus.com/us/Motherboards...pecifications/

https://www.amazon.com/Asus-Hyper-M-.../dp/B0753JTJTG

now the motherboard says that it supports one of these cards.

is this how you get the full benefit of the M.2 in a performance array?

it looks like I will need intel M.2 SSD's on this card for it to work, but I can't seem to find a list of compatible drives?

https://www.amazon.com/Intel-Optane-...m.2%2Bssd&th=1

than do I use this type of M.2 memory, on the motherboard itself?

sorry for all the strange questions, I am just trying to get a grasp of the new hardware, and how it functions. so that I don't buy a bunch of stuff that does not actually work, or that is not needed.

First you should ask yourself what sort of performance you want:

High Sequential Reads/Writes for OS (boot drive): Hardware RAID 0

High Sequential Reads/Writes NON BOOT DRIVE: Software or Hardware RAID 0. Software recommended for universal compatibility.

High random I/O performance NON BOOT DRIVE: Drive Pool (Note that random i/o performance benefits are achieved at the file level and not the block level)

If you want both high sq RW and random I/O you need to build a Drive Pool of 2 drive RAID 0 arrays. (Thus minimum 4 drives required).



The sq reads of most high end NVME drives will saturate a 10gbe connection. So generally your not going to get much improvement using raid 0. This is why it is so uncommon with NVME drives. Most people would like improved random I/O but they do not understand that RAID has no impact on this other than usually a negative impact and that it is for this reason many businesses are using pools vs raid for high performance random I/O mix.

well realistically, all I use my computers for, is to play games. so, I have a 3930K system at 4.6Ghz, and a FX9590 system at 5Ghz, currently. I am looking to build a 8086K at 5.1 to 5.3Ghz, for my new gaming system. this time around I would like to use some of the new hardware available today, if it will create a faster system. on my last gaming system I got 2 X intel 3700 200gig SSD's in a performance array for my O/S drive, I still have those drives, and they work fine. I was planning to build a performance array out of them, to use as extra storage for the new system. so what I am after is understanding of how to build a great O/S drive for this system. what hardware I should be using, and how should I configure that hardware?

if I am understanding the post above, I would need two compatible intel M.2 drives in that expansion card, the only thing it does RAID 0, and it seems like, the expansion card allows for the higher transfer rates. does this sound correct?

Negligible difference in gaming, more potential headache and you have to spend an extra $67 for that expansion card. This is one of those things that sounds cool but isn't worth it.

so just a single M.2 connected straight to the motherboard?

or stay with the SSD's in a RAID 0?

I second that, no point in bothering with raid 0 for gaming. These high end NVME drives are already plenty fast.

If you don't already own those 256GB 950's, I'd suggest just getting a 512GB 970 instead.

I am no expert, but I have read that the new V-NAND 2-bit MLC controller has issues?

this is why I was looking at the 950's, because of the V-NAND UBX Controller has had a lot of compatibility issues resolved, was hoping this would allow me to avoid adding instability in the system?

true, not true, thoughts?

The initialization time on boot for the RAID array is likely to be more noticeable than the load time decrease in games going from a single NVME drive to two in RAID 0.

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
