[SOLVED] Is it possible to set up raid in this configuration

[Rick.2013]

When I built my system I got a wd blue 1tb m.2 ssd and a wd blue 1tb 3.5” hdd. If I got another m.2 ssd of the same type and size could I configure them in a raid 0 array and then mirror those to the 3.5” hdd like a raid 1 array? Is that possible? Or would I have to get another hdd and do a raid 10 array? Thank you in advance!

Or you could just get an nvme drive and it would be faster

HDD + SSD in the same RAID array reduces the speed of the SSD down to HDD level. In any RAID configuration.

Why the desire for the RAID?

Just for experimental reasons. No real use for it. Trying to expand my knowledge base

Could you?
Maybe.

Many things to consider, starting with does your motherboard accept 2x M.2 SATA drives?

Ultimately though, this would cripple the SSD performance.
In the consumer space, RAID of any type is rarely the answer to the oft asked question.

 

[Rick.2013]

To change the situation would having the 2 m.2 ssd in raid 0 then another 2.5 ssd mirroring those in raid 1. Is that possible?

Possible? Probably.
Advisable? Not a chance.

You'd need a 2TB 2.5" drive to 'mirror' the 2x 1TB.


SSD + RAID 0 gives pretty much zero user facing performance benefit.
It simply does not stack as it did with HDD's.

My mobo is a gigabyte z390 aorus master. It has 3 m.2 spots. 2 110s and an 80

 

[Rick.2013]

If the 2 m.2s (1tb each) are in raid 0 then they would be only 1tb of space correct?

That can take a M.2 SATA drive in the M2M and M2A ports.

Still doesn't make it a good idea.

No.
1TB + 1TB + RAID 0 = 2TB RAID array.

 

[USAFRet]

RAID 0 (striped) adds the drive space. 1+1 = 2
RAID 1 (mirrored) means the size of a single drive. 1 + 1 = 1.

Sorry got them mixed up in my head. I’m not trying to gain performance just experimenting. But with the 3 ssds would it be easier and basically the same to run a raid 5 array?

1+1+1+RAID 5 = 2TB actual drive space.

Not 'easier' in any definition of the word.
Just have them as individual drives.
1 for the OS and applications, the others for all your personal data, games, other things.

My system has 7x SSD (see below) No RAID in sight.

Right now mine is set up where my os and other read only stuff is on the ssd. Everything else is on the hdd just for longer life of the ssd(so I’ve been told)

SSD lifespan is not really a concern anymore.
After the first gen of consumer grade SSD's, they fixed that real quick.

Current drives have, depending on size and manufacturer, a warranty limit of 150-1000TBW, or some number of years. 5, maybe 10 for expensive pro level dries.
All my SSD's together don't add up to 75TBW. Some of these drives are now 5 years old, been running basically 24/7.

In actual endurance testing, normal consumer SSD's have been tested out to hundreds ot TBW, in a few cases over a petabyte before they died.

These, and yours, will be off warranty long before they 'die' from too many write cycles.

 

[Rick.2013]

Well that is good to know! For what I’m running I’m sure I’ll never see the end of my ssd then. Thank you so much for the help and knowledge!

 

[USAFRet]

For the record, I've not read of anyone in here who went past the warranty TBW on their SSD in normal consumer use.
And especially not anyone whose drive died from too many write cycles.

There have been some that died for other reasons (one of mine included), but none from writing too much.
