What is the consensus on stripe size for ssd?

post #1 of 8
Thread Starter 
Hi all.. Just purchased two more 128gb crucial m4's to add to my other two in a raid 0 array. I will be reinstalling my os this weekend to make it. I currently use a 128k stripe for my two drives in raid 0. Now that more and more people are exploring raid with ssd's has anyone arrived at a best stripe size for a gaming computer? I am not really sure if loading games is consisting or larger files for which 128k would be better or if i should use the intel recommended 16k stripe. I have been reading threads all morning on this topic and each seems to have their own answer. Can you help me out?

I usually use 64k if its available.

Its a good balance between performance and "straining" the array.
But thats for mechanical drives, and the performance differences are pretty slim from what ive seen.

For an SSD I cant say im certain there would be any benefit in RAID 0 to using a smaller stripe size.
0 isnt generally used to increase performance the same way 1 is, so I would probably use 64 or 128.
Plus, SSDs are already so fast that larger stripes probably wouldnt do anything but make it more stable with no real performance impact.

I am kind of unclear on why intel recommends 16k if everyone else seems to like 64k or 128k. Also benchmarks seem to indicate 16k scores lower. Perhaps it is the large seq. reads that influence these scores heavily?

Always found 64k the best all around size.

Would you classify the rules similar for ssd vs hdd?

My personal preference, 32k on the system ssd, 128k on disk based storage. That's what's treated me the best.

Thanks for the reply. I ended up going with 16k stripe but 32k was a close contender. Results aren't too bad for sata II
