Best Stripe size for SSD Raid 0

post #1 of 5
Thread Starter 
Hi,

I am raiding two Crucial C300's 256g.
Wanted to know best stripe size.
In searching the internet, I find recommendations from 4k to 128k.
Is there that much difference? what is recommended?

I use the system primarily for gaming.

I am getting 934 is AS SSD right now

I would just leave it as it is mine is 128kb I think. Raid is more of a thing for HDDs, even tho we've done it on the ssd. Changeing the strip size wont affect game play at all, It might get better results in benchmarks.

Normally larger stripe sizes improve positional performance on HDDs, but since positional performance is nearly irrelevant on SSDs all it will do is lower controller overhead.

You would likely get optimal read/write speeds with a smaller stripe size, at the cost of some CPU utilization.

16-32k might be a good compromise.

Really though, I'd probably keep those drives separate and go for redunancy/backup over raw speed. Just having a decent SSD is going to put 99% of real world access performance back on the shoulders of the CPU.

Thanks.
I run windows home server, so I am fine in the backup/redundancy department.

I guess, I am just looking for the best performance (technically speaking) although I may not notice it in actual gaming experience (this is overclock.net after all!).

If you can, test a few different stripes. If you can't, go with a middle setting.
