I have an Asus Z87 motherboard and two Samsung 850 EVO 1TB SSDs. I want to set up a non-booting RAID 0 drive and have a couple questions. 1) Should I use the motherboard or Windows (I'm using 8.1) for RAID, what are the (dis)advantages of each. 2) I know SSDs write data in specific chunk sizes, is there an optimal stripe size I should use for SSD RAID 0?

That will benefit exactly zero with a 2 x 1TB SSD RAID 0.

As much as we'd all like the RAID 0 + SSD concept to scale up as it did with HDD's, the difference is not there, except for a very few limited use cases.
All you gain is complexity and fail mode.

Many people do this and then boast about their benchmark numbers.
Yes, the benchmarks are seen to be great. But unless you are selling something, or are very weird...no one actually uses 'benchmarks'.

What is the actual speed difference between RAID 0 and no RAID 0, when writing a file of 75MB to that drive or array?
Interestingly, no one ever comes back to show a documented benefit. All I ever see in here is "MY BENCHES!"

I'd LOVE for it to be the case that regular real world use benefits from a RAID 0 SSD.
So far, I haven't seen it.

I have a couple of 840 EVO 250GB, ready to use with this. I am not sufficiently convinced it is worth the effort.
