Raid Question

[mosh1e]

Hi,

 

I have a rig with 3 hard drives 

- Intel SSD (240 GB)

- Kingston (240 GB)

- Samsung SSD (2 TB)

 

I am looking to setup raid after watching a few videos raid 0 sounds like it could be the one. (not sure open to suggestion..)

 

I am not to fussed about redundancy just that juicy performance, plus I back up my data regularly anyways.

 

My question is since the data is striped across the smallest amount in this case 240GB what happens with my 2TB drive will I still have access to the 1.86TB?

 

If not is there a way I can have raid0 but still keep the whole 2TB?

 

Do I need to have all drives in raid0 or can the 2 TB one be separate?

 

Thanks,

Why do you want to RAID 0 SSDs? What exactly are you transferring across 240GB of storage that 500MB/s or so doesn't do in a timely manner?

 

This is tons of risk with almost no benefit.

If you put the 2 SSD in a stripe (Raid 0) your volume will be 480GB 

your 2tb will still be 2tb, since you are not putting that into a stripe.

most times 2 ssd in a raid 0 is not any better that one larger ssd by itself

 

If you somehow wanted to put all of your drives in a stripe, normally you do it with drives of all the same type, not mix and match mechanical and ssd, you would run into issues immediately. But if somehow you wanted to try it , though i do not recommend under any circumstance , you would need a raid 5 , not a raid 0.

Even as your build is with the intel ssd and kingston, i wouldnt put them in a Raid 0 together, like i said before, usually drives of exactly the same model and spec

Thanks, I am kinda new to this stuff.

This was very helpful!

 

With the 2TB drive if I didn't put it in a stripe could I still access it?
 

You mentioned not mixing the type of drive can I mix the make of drive? - Sorry Just noticed your comment

When you put 2 drives (or more)  into a raid, they become one. So 2 x SSD Raid 0 , would become one larger Raid 0 SSD. As long as you dont put the 2tb in a raid then it would just a regular old disk.

 

Even inside of the same make, they would have different read and write speeds, i suppose you could attempt it if they had identical speeds, but usually you want to keep the exact make and model so they are both capable of exactly the same speeds etc

Also it makes a big difference if say you had a 240 and a 480 ssd that you wanted to stipe (raid 0), in that case you would only get the most of the smallest denominator, so those stripe would only be max 240GB.

 

Raid takes a while to wrap anyones head around, but once you got it down pat , it comes easier.

 

This is a good explanation of what each raid level does, its sort of alot to digest, but its worth a read

Thanks, I will give that a read!

Keep in mind if you add the 2 drives into RAID, the data on them will be destroyed. Make sure you backup before you do!!!!

IIRC you need to have 2 of the same drive. Also, you're adding multiple points of potential failure. Considering the size you're going for, I don't see the benefit.

Just get an NVME drive.
