What stripe/block size should I use - RAID 0

post #1 of 15
Thread Starter 
I am setting up a RAID 0 array tonight with my two 250 gb WD (not raptors).
What stripe size should I use?

my primary goal is to speed up boot time and load times on games like BF2142.

Well, when my Raid was working, I used a 64k stripe with default block size.
That was a good combo for BF2/2142.

Go with 128k strip. Thats one of the fastest ones available I think.

From what I gather most people are using 64K, but SUPPOSEDLY 128K is faster...i'm going to go do some research now

ok, research done...

If the sectors accessed are spread evenly between the two drives, the apparent seek time of the array will be half that of a single drive (assuming the disks in the array have identical access time characteristics).
The transfer speed of the array will be the transfer speed of all the disks added together, limited only by the speed of the RAID controller.
So, it appears that the only thing affected by stripe size is seek time. Read/Write is the same no matter what.
I guess I will be going with 64k.

A larger stripe size is also better for gaming. I use 128k.

that is what my research into raid has come up with,
if you are accessing small files a lot then smaller stripe sizes are the way to go, bigger files bigger stripes. thats why gamers tend to go for 128k
if your running vista apparently those hybrid drives are pretty impressive (drives that utilize both hd and flash).
