Volume or Partition?

post #1 of 6
Thread Starter 
I have a RAID 0 setup with 1200gb total with 2 physical HDD's

Should i create 2 Volumes in the RAID config utility and set two different strip sizes like 64k for Apps and 128k for Data?

Or just go with one big Volume and create 2 Partitions in Windows, Since ill create the Apps partition first it will be for faster performance so like 300gb and the rest is for Data.

Or is the same doing both these methods.

If I remember correctly...you can't setup separate/different arrays in the same RAID configuration as you're automatically choosing your RAID size upon creation.

Example: You have your two 640GB drives that you decide to setup in RAID-0 but you decide to use only 300GB out of the 1280GB because you think you can use the other 980GB for a separate array volume. Fact of the matter is that you can't as the RAID array you created is its own array and you'd have to use different drives to create another RAID setup.

Note: Someone may need to confirm this as I always use the full volume for all my RAID arrays.

EDIT: Seems LiNERROR has confirmed me wrong so you should listen to him.

You benefit from creating a small sized RAID-0 array aka short-stroke with faster seek and a high constant read/write speed.

Feel free to do your second option if you want to...but I personally hate setting up separate partitions when you're still dealing with the same drive(s). I always tell people to have a separate storage drive aside from their main operating system drive...so my opinion would be to keep your current RAID-0 setup and get another separate drive for your personal data.

you can have different raid volumes in a raid set...

i have 2 500gb drives in a simple i5 machine with the onboard intel matrix raid... setup with 310gb Stripe and a 310GB mirror...

use 64kb for stripes, 128kb for mirrors

short stroke for performance... ie your first 300gb will perform faster than your last 300gb...

Already edited my first post...but I'd have to say that setting up different type of RAID volumes would seem a little awkward but I'll keep that in mind in case I might set that up as well.

bear in mind that by creating separate partitions OR arrays, you force your data to be further apart on the disks, meaning any seeks between your OS & apps partitions will take longer.

As a result (depending on your usage) you may be better off using 2 separate drives (one for OS, one for Apps) rather than running 2 partitions/arrays on the same RAID0 drives.

Well i have an SSD for my OS, my plan was to use half of this RAID 0 for Applications so using the first 300gb hence making the first Volume 300gb and the rest what's left over for personal Data.

So like this


------------RAID 0 1200gb------------
1st Volume______________2nd Volume
Apps (300gb) 64k_________Data (Ramaining) 128k


The Data Volume won't be accessed frequently at all, mostly the Apps will be accessed on a regular basis. or should i just use only 300gb and after that fills up use the 2nd volume or just setup 2 partitions on one volume.
