[SOLVED] Raid 0 or 1 in M.2 NVME requirements

[Hardquery]

My old gigabyte amd phenom III am3 board got dead so I am planning for new build of ryzen 7 3700x and I used to do professional work of data recovery graphic designing vedio editing and website development I used to have multiple OS instance of windows xp 7 9 10 and linux or different work and used to image and clone HDD SSD with acronis disk director and have not worked much in raid of HDD or ssd drives

As I do R & D in system windows registry for learning and many time I get problem in windows crashing and it its tedious time consuming job to install multiple OS and multiple software installations and reconfigure multiple software settings again. So I backup or keep image of bootable drive to recover the system drive within hour.

Now I wanted to get two Samsung 970 evo plus pcie 3 1TB drive as bootable system drive for multiple OS windows and linux .So i wanted to install Raid 0 for parallel writing or. Raid 1 For mirroring and make it work.

For that I want to select a motherboard which is good speed in Raid as all b450 or x470 motherboards and b550 or x570 motherboards to have Raid option. But someone commented in my question that MSI boards use SATA III arrays for raid 0 or raid 1 . Does Gigabyte or Asus to use sataa III arrays for raid 0 or 1. I want that raid works in Pcie3 is 3500MBs or pcie 4 7000 MBps is it possible in any and board of gigabyte or Asus. Which company motheboard will be good for raid arrays speed?


Secondly for motherboard selection Manny b450 x470 boards M.2 1 first socket is pcie3x4 (3500mb PS) and m.2. 2 second socket is pcie 2x4 (1690mbps) only Asus b450 x470 boards have both first and second M.2 socket with pcie3x4 (3500 Mbps)

Many b550 x570 motherboards have M2.1 first socket slot of pcie4x4 (7000MBps) and M2.2.2 second socket with Pcie 3x4 (3500MBPs) whereas x570 generally have both slots have pcie4x4. ( 7000MBps)

I all I mean to say that for raid what is recommended preffered that both M2.1 and M.2.1 have same speed of pcie 3x 4 or pcie4x4 does the speed of slot effects the speed in read and write of motherboard Raid 1 mirroring or Raid0 parallel writing. If I put samsung evo 970 evo pro NVME m.2 gen3 drive in first m2.1 slot socket with pcie3x4 (3500MBps) and second. samsung evo 970 evo pro NVME m.2 gen3 drive in second M2.2 (1690MBps) slot socket then will Raid 0 or Raid 1 perform in 3500mbps or 1790mbps speed.

At last there are many pcie m2 adapter cards are available with multiple m.2 sockets or single m.2 socket as they can be inserted in pciex16 slots will they perform at same speed as motherboard sockets and slots it they gave latency problems. Secondly does these adapter cards good for Raid 0 or Raid 1 configurations. Thirdly can we use one m.2 socket of motherboard and another of adapter card to get good raid speed.
Kindly tell me if Any more requirements seetings configuration of motherboard drives or item should be considered and taken in mind or concern of configuring raid on m2 NVME drives.

Waiting for advice and opinions

Thank you thanx in advance for your precious time and for your precious advice and opnion

a single NVME drive is quite darn snappy; as long as you have working image backups, RAID /mirroring 1 is pointless, and, effectively a waste of an NVME drive.

RAID 0 only sounds 'twice as fast', but, short of a few very select workload instances and sequential read/write benchmarks, most won't notice any perceptible difference anyway. Put that money into a larger NVME drive (2 TB vs. 1 TB, etc)

RAID 1 - mirroring.
Only benefits actual uptime. In the rare event of a physical drive fail, you can limp along until you can schedule downtime to replace the dead drive.
Like a POS system or a webstore, when downtime = lost sales. And any RAID 1 needs a full backup anyway.
Does nothing for actual data loss. Virus, accidental deletion, corruption...RAID 1 does not protect against that.

You need an actual backup routine.

What is your backup situation at home?

What is your backup situation at home? And if you don't do that, why not? Every single day, I read multiple threads here of "How do I get my stuff back?" or "That drive had 5 years of photos of my kids!!" Be it a dead drive, dropped phone, virus, accidental deletion, formatting the wrong...

RAID 0 - striped.
In certain use cases, this was sort of a good idea with HDD.
With SATA III SSD, useless. With NVMe, worse than useless.
It sounds like a great idea. In practice, not so much.

One SSD Vs. Two In RAID: Which Is Better?

One SSD is good, right? So, two SSDs in RAID 0 must be better. That’s certainly the case when you're benchmarking sequential performance. But we're finding that, except in extreme examples, one SSD that's twice as large is often better.

@USAFRet bro happy new year 2021 and lots of wishes. thanks a lot again to clarify my doubts for Raid..too great for you to guide and clarify the concept In detail.

@USAFRet bro yes it's truth advice that RAID 1 is mirroring and mirroring protects downtime and not from virus or data loss....I knew and had a bad experience of ransomeware virus in one day factory IT office I we worked on 2019 in which mirror HDD. Failed corrupted encrypted data and was nearly impossible to recover data.....I forget it thanx for reminding. I used to use Acronis or Norton or eaaeus or Windows shadow....for image backup which was secure but scheduling used to make pc slow.

Actually I use desktop not only at home but also i had a computer center where I
have computer lab of 20 desktop Am3 PC for teaching and do professional job work like designing flex marriage cards publication books printing website designing development programming hardware assembling formating data recovery formating and many more it related works. So as multiple students people access the pc and use flash drives it's high risk of virus changes of setting and corruption of windows so I used to handle it with disk images but scheduling it in official hours make pc slow and unusable many time . For me to downtime means loss or delay of work to customers.


So I was thing to give A try to Raid 1 but thanx for your advice make me member my past experience with Raid .mirroring may I have to drop the idea. I was thinking that in NVME it may be fast and not make pc slow.

As u suggested for routine backup or scheduling is there any software or way to take routine schedule backup of windows shadow copy and save it on online drive and recover from there or type of snapshot backup so that CPU memory or system resources are less usable and make backup fast...as windows shadows copy are small files and snapshots to are small.

Secondly I want to start and give a try and install linnux OS like Ubuntu or my new build will image backup like Acronis take backup of Ubuntu files as Linus file system ext is different then windows fat. will routine scheduled imaging work for Linux....and as windows shadows will also not work for Linux...what will be alternative to backup Linux ext from Windows....

RAID 0 - striped.
In certain use cases, this was sort of a good idea with HDD.
With SATA III SSD, useless. With NVMe, worse than useless.

@USAFRet bro thanx again a lot for sharing info and links for Raid 0 benchmarks. For ssd. It cleared my knowledge and concept of raid 0. Actually I have not tried raid 0 ever but some artical I have readed that raid 0 in m.2 Nvme make parallel or strip writing. and doubles the speed in pcie 4 and pcie3 as dual Ram concept...but as u shared the benchmark link which clearly shows it's not beneficial for ssd or Nvme to thanx and grateful to share knowledge hence I drops the option of Raid.

Last question as for image sector to sector backup or cloning we would need 2 m.2 Nvme or it can work from M.2 Nvme to ssd. If we use cloning then do M.2 second Nvme
should be same speed as first slot lanes pcie3x4. what will practical effect in cloning if first slot is pcie3x4 (3500mbps) and another slot is pcie2x4 (1690 MBps) as I think Samsung 970 evo pro in synthetic crystal benchmarks gives speed of 1500-1700 MBps will pcie2x4 sufficient for backup or real time work it or it will effect much on practical work speeds or the speed only reflects in synthetic benchmark

@USAFRet bro happy new year and lots of wishes to you.thanx again in advance for your precious time advice opinions knowledge shares and apologies for long replies as I try to explain in detail my situation and queries and their reasoning

So have an Image. Overnight, when no one is using the systems, reimage them, wiping out whatever virus things the students did to it.
