Short Stroking: Am I doing it right?

post #1 of 17
Thread Starter 
My RAID 0 drives were set as unallocated space, I created an 80GB partition for the OS and formatted the rest for storage. (80GB = 40GB each drive, 466/40 = 11.65% of the platter, on the outside edge going in).

Here's some speed results:

Each drive separately:

RAID 0:

Well if you're getting a speed increase isn't it pretty obvious that you're doing it right?

Haha yeah I guess so. I just wasn't sure if I made the OS partition too big or not.

Short stroking is about access time.
test it with HDtune.

You're not going to see a difference if you run HDTune on the whole drive, but the important fact is that your OS is on the left side of that graph, where the read speeds are highest, and access time is lowest.

looking at the second pic, you only tested the entire raid setup, which gives you the same access time.
Looking at this thread, you can select a raid volume, the 80gb you crated and test that one. Can you do that?

I don't think you can select just one partition. I'm sure it's working just fine, as long as the OS partition is the first on the disk.

Doing it wrong. If you have the rest of the volume formatted for storage you haven't short stroked. Anytime the OS does anything with that second partition your access times will get hit.

To really short stroke you should have set the array to around 25% or less of the size of the discs and not used anything else.

I used to have a short stroked 2 disc array, looked like this:

My SSD is waaaaaay faster.
