can anyone give me a quick guide on how to set up raid 0

don't ... that is my guide... and will ever be. far to much chance to lose all data.

Basically all motherboards support it soooooooo

STEP ONE: Install the drives

STEP TWO: Realize you were stupid and your motherboard doesn't support raid for some reason (If motherboard does skip this step and move to STEP SIX)

STEP THREE: Buy a new one that supports raid either online or at a real store.

STEP FOUR: Remove old motherboard and take all the components installed on it out.

STEP FIVE: Install other components into case/motherboard like it was before.

STEP SIX: Boot into bios go to find the way the drives are connected are set it's connection to RAID.

STEP SEVEN: Different for all motherboard's so I don't know what's next, I would find wherever it says raid and there is probably some kind of on switch somewhere in the bios.

Raid0 was an idea that came up so that data would be written/read to and from a HDD.  Back in the good ole days hard drives could only do the read/write process so fast so Raid came about with the idea that if they wrote the zero's to one drive and the one's to a different drive then basically they could cut the read/write process in half.  That was back in the day when HDD's ran at 5400 or 7200 rpm.  My but how things have changed.

 

With the advent of SSD and NVME, that process no longer applies.  Technology has brought us to the point where certain tasks, no matter what that task was, could be done just so fast and basically no faster.

 

With SSD and NVME drives, there is basically no return on investment when connecting two of the drives in a Raid0.  You really don't save any time to speak of because electricity and current travel only so fast and no faster.  If you want to create a system for data saving and making sure things stay as they should, then Raid1, but not Raid0

 

So, with SSD and NVME there is no advantage so there is no reason to go Raid0.

Yes there is, connection speed is limited so it is much better to write half to one drive and half to the other instead of flooding one drive.

I guess my 45 years of experience and my college degree in electronics was a complete total waste of time and money then.  If it is so much better, then why don't comsumer computers come with two nvme drives in raid0 from the factory?

Because it costs way to much. Raid with nvme drives is for enthusiasts who want the fastest stuff for some reason. You are right though the speed will go up but not as much as with hdds or normal ssds.

And some times after a bios update enthusiasticly get their data flushed down the drain, like happened recently for one person on the forums here and lots of others.

 

Raid 0 is from the calculating point of view the 200% chance to lose all data compared to 1 disk/ssd. Because 2 drives could fail, and if one fails all is gone. With one drive yes could happen too, but the chances are less. 

 

If Raid, do a read one... writing doesn't get faster but reading...

I did not say it could not be done.  I said it was not, and is not, practical.  Electricity travels as 300,000 kilometers per second.  Basically no slower and no faster given all circumstances being the same.  If you are determined to waste money on a SSD or NVME Raid0 setup, go for it but don't forget, in a Raid0 system, if one drive fails, then the system fails.  If you are hard up to use SSD or NVME drives in a Raid setup, then use Raid 1, not Raid 0.

I'm just curious given the conversation here so would someone please enlighten me.  If the speed of electricity is understood to be a given both coming and going, then why would reading data from an electronic device be faster than writing that same data to the same electronic device?  That must have been the day I missed school sometime back in the early 70's.

 

The speed of light, often called "c", in the lower case, commonly refers to the speed of light in a vacuum, which is the fastest it will go. Its about 300 million meters per second.

Not sure I'm allowed to do this but about half an hour ago LTT released a raid 0 setup with four 512 gigabyte Samsung 960 pros on Floatplane. Not going to say numbers but he did do it.

I never said it could not be done, I said it was not practical.  And you didn't answer my question.   If the speed of electricity and light is understood to be a given both coming and going, then why would reading data from an electronic device be faster than writing that same data to the same electronic device?

I don't think I am qualified to answer that.

[Anghammarad]

Yes you can do that, and yes the throughput will be faster... measurable, when copying files around like a mad data shrubber... but else I don't think you will fell much speedup from that.

 

And that for it would be just too unreliable for me... and LTT isn't the first that did that.

 

I would go for, IF, a mobo with 3 m.2 slots and make a raid 5.
