Short Stroking 3 x 1TB Drives

post #1 of 5
Thread Starter 
Hey guys, been reading on the stickies about short stroking drives. My raid array hasn't exactly been performing that optimally, considering looking at benchmarks from everyone else. So ideally i'd like to short stroke the drives. My question is how would you go about short stroking 3 x 1Tb drives?

I was reading that you would usually do 20% of the drive, seeing as each drive is 1Tb would you ideally do 200gb per drive? Setting the active array size as 600Gb? I've also always kept the stripe size at 128k, but was reading that 64k would be better for OS read/write. So what would be optimal for a Raid 0 array? Thanks for the input.

If you do a benchmark with a graph such as HDtune, just short stroke to the capacity where your sequential performance starts to drop off.

Also, you aren't going to gain much as far as random R/W by adding more drives to a RAID0 array. The main benefit is sequential performance. Access time is hardly affected.

Okay that makes sense, so you think that 2 drives would be sufficient?

That depends entirely on what you're doing. If you're doing anything that requires high sequential performance, go crazy and keep adding drives to your RAID-0 array.

I ended up setting the size to 600Gb. As far as performance, it seems very solid now compared to before. Thanks for the input!
