Have I set this RAID 0 array up correctly?

I got my second Seagate 250Gb drive (single platter) this week and have just setup the two of them in a RAID 0 array, using a 32k stripe. This is my first time of setting up a RAID 0 array and took advice from here and it looks to be running fine.

I was quite surprised when I saw that Windows detects the array as one drive, but twice the size - is this normal? I was expecting it to show a 250Gb drive not a 500Gb one!

Also, is this HDTach large run correct? I guess this means I've set it up fine, and that it was a lot easier to do then I thought it would be

raid 1 (mirroring) shows up as one disc with the capacity of half the component discs, raid 0 (striping) shows up as one big disc with the capacity equal to the components.
assuming you wanted the performance boost, and not the protection against one of the discs failing, i think you set it up fine.

Yes I did want the performance boost

All my data is on a separate drive.

So I essentially have a 500Gb drive that is twice as fast? I guess I didn't read up properly

Thanks.

Always thought that was a pretty good discription

Yes.

Pretty good speeds there. I get 130mb/s with my two WD 2500AAKS drives (don't think they're single platter) on a 16k stripe.

Here are a couple of benches of mine, using 2 x 250GB 7200.10's (single platter) in RAID0, no difference really...
