4 way 120 gb ssd in raid 0 will i get a combined storage of 480gb? or 120?

[walachewaka]

will i get 480gb of storage if i have 4 ssds in raid 0 or will the total storage be 120 gb?

im considering this solution because im building a pc made for speed and compact. wondering if raid 0 is worth it or if i loose space and only get 120gb of space over 480.

Yes, it will be a 480GB drive.
No, it will not be worth it in terms of 'speed'.

Read this all the way through:

Better to just buy a 500GB SSD. Just as fast, and cheaper than 4 x 120.

480GB, but the risk of losing data will be quite high; a single SSD failure and all contents is lost. It's fine for a scratch disk, but I wouldn't recommend it for an OS or valuable data. If you store important data on it, then perform regular backups.

however, i already have 1 ssd and im considering getting another 3 for 4 way raid....

Don't.
You can add other SSD's, but the RAID concept you're thinking of will not add the performance boost you anticipate.

the speed i am getting is quite fine, but adding more ssds in raid 0 will get me a 480 gb drive at 500 mbps read and write? if i am right this to me is fine....

Adding 3 more 120GB SSD's and incorporating that into a RAID 0:
It will not get you any faster speed than what you have now.
It will not get you any more drive space than just adding the drives as individual drives.
It will increase your fail potential.
It will increase the overall complexity.

There is zero reason to RAID 0 small SSD drives, unless you really, really need to...as in a target drive for a large rendering farm. For everyday use? No.

For instance:
I have 2 x 250GB Samsung SSD's
500GB space. 2 drive letters, currently G and K.

If I were to RAID 0 those 2 drives, I would still have 500GB drive space. But with added fail potential, and zero performance benefit.

 

[walachewaka]

how can you have 2 drive letters if they are combined? and you have 500gb ? if you have 2x 250gb

They are not combined. Just different drives.

In my main PC, I have 5 drives:
120GB SSD - "C" boot drive. OS and all applications
2TB HDD - "F"
250GB SSD - "G"
3TB HDD - "H"
250GB SSD - "K"

No RAID needed or wanted.
Theoretically, I could put the two 250GB SSD in a RAID 0 volume, resulting in a single drive letter. Drive "L", maybe. But it would gain zero performance benefit, and increase the fail and complexity. No need for it.

ok, now i see...
thank you for all your support.
