Raid0 Stroking, how does it work?

post #1 of 12
Thread Starter 
I've read that stroking the raid0 basically finds the optimum 'sector' or 'area' where the speed of the hd is the fastest. Stroke it, and install the os on it. Is this correct?

I'm curious though, after viewing benchmarks, people had a more stable result as opposed to the "high-to-low" results that most mechanical HD's show.

How does stroking produce more stable read/write results.

Also, when you install the os on the stroked partition is there a certain way to set this all up. Will the OS recognize the stroke partition and put the C:/program folder on the non-stroked parition?

blue.

Short-stroking = manually reducing capacity of RAID 0 array.

Instead of allowing your RAID 0 array to use the full capacity of both hdd's, you reduce it. A smaller partition size. For the most part, it improves the access time. Programs/games load faster, and an improvement in Windows loading time.

Short stroking is not worth the loss in disk space imo. Smart partitioning will accomplish the same effects as short stroking.

Short stroking?


Short stroking is pretty hard to explain but the point furthest from the center of the platter is the part that moves the fastest. Therefore it can read / write faster in those sectors then the others closer to the center.

It really is just a illusion.

If you look at a Before / After short stroking benchmark you will see that its actually just the top 1/3 or 1/4 of the before short stroking benchmark.

Do you see where im going here?

Yeah I get what you mean.

Thanks for the other explanations as well.

If you stroke say, 100 gig from your 1TB, do most people just use it for the OS, or do most people use it for the OS + programs/program files and use the rest of their HD for storage space?

If you look at any hdtune graph for a mechanical drive, you'll see that there is a curve in transfer speed the farther inside of the platter you go. By 'short stroking', you limit your OS partition onto the outer edge of the platter to maintain the fastest read/write possible. If you simply used one giant partition, you would have no way of limiting certain operating system files onto the edge of the drive..

that's might be true.

They are similar but not the same. Short stroking is telling the RAID controller to limit the array size. Partitioning is the OS/filesystem limiting the array size.

The onboard Intel RAID controller only allows two arrays on the same drives. Partitioning does not have that limit.

Short stroking is forcing hard drive accesses to be restricted to the outer edges of the platter. Taking about RAID controllers is all well and good, but that does not apply to a single hard drive.

The effect of short stroking can be achieved through partitioning (RAID array or single drive), limiting the array size (RAID array) or both.
