RAID-0 Questions

[CerealToys]

So this is what I know so far about RAID-0. Two SSDs, data is split between the two. When one SSD dies then the other is rendered useless because 1/2 the files were on the dead drive. Right?

 

Now if I were to run RAID-0 on my computer with brand new SSDs, what factors can make my SSD unusable other then aging? How long is the lifespan of an SSD that is in RAID-0 setup? Overall is it worth risking your storage for the extra speed? I've seen some setups with all kinds of SSDs but I was wondering which one is the go-to-setup when it comes to RAID-0?

The real question is: Why do you need something faster than very fast - rather than more storage space?

 

Power surges, manufacture flaws, usage amount, etc will determine how fast something dies. Many will last for years. But really, just back it up to another drive every night, and then it doesnt matter.

Well, most people won't notice the speed improvement with RAID 0 on SSDs. 

The SSDs being too full is one problem that kills them faster than normal (re-writing to the same cells over and over). 

 

Too long. Like really. They can usually survive Petabytes being written to them, which having them in RAID 0 halves their normal write-rate because half the data goes on another SSD.

 

You aren't really risking your storage because SSDs are so reliable, and you aren't really getting extra speed because 90% of consumers can't use the extra bandwidth. You might be the exception, but even then, it's rarely noticeable.

Not sure what you mean by "go-to-setup". What other options are there?

I personally have Four SSDs in RAID 0 because it's easier to have them as one giant volume than Four 120GB volumes for managing my storage. I did it for convenience more than anything. I'm not worried and I don't notice the extra speed.

YMMV, I am not a medical doctor, lawyer, or accountant.

RAID 0 seems like a neat idea, but for most people it makes no tangible real world differences.

 

by most people I mean anyone not building a computer for heavy RAW video editing.

 

for gamers you will literally not be able to see any difference

 

and since drives in higher capacities tend to perform better in random read/writes, you will be better off buying a higher capacity ssd rather than raid two lower capacity ssds

 

the average user should only use RAID for back up purposes. 

 

But, to answer your question, SSD life span is mainly dependent on write volumes, most ssds have around 70 tb of lifetime writes.

Go-to-setup as in which SSDs do people commonly use when they doing it in RAID-0

But after reading your response I'm curious why people would consider running RAID-0 on SSDs if we can't notice the improvement? It seems to me one of those things where people just do to get the maximum amount of performance even if that performance is ever so slightly increased.

I think its a combination of:

1. I know raid0 is faster right, so, therefore I must RAID0 my SSd's for powa!

2. e-peen

3. I edit RAW all day or transfer 20GB files all the time.

Well no I am much more informed about this topic than before. I will definitely look into buying a higher capacity SSD rather than the RAID setup. Thank you all for helping me out!

there are no such thing for go-to setups for SSDs IMO, RAID 0 doesnt really affect the way your ssds age. so if you want longer endurance go for a samsung 850 pro but that same logic applies with a single ssd config.

I think Spyware scans seem faster on raid 0 SSDs. that's a noticeable improvment for normal or real world use. A scan on a system with a single ssd seems slower on than our other system with raid 0 ssds.
