Half the reads and writes... what? I thought that was bad...

And I have a few questions about how to partition my array... I usually do the following on a 1TB (~930GB usable) 4-way array
  1. 130GB partitioned to OS and non-removable apps
  2. 780GB partitioned to user's folder (documents, vids, etc), Program files, desktop, etc
  3. ~15GB partition in case I need to install secondary OS to boot to if my original OS gets corrupted, or if I want to temporarily set up a dual-boot situation which I prob will use for folding (Vista32 cut down to use for night-time folding)

Should I have instead done two separate RAID-0 arrays, one for OS, one for data storage? Since I am reformatting this coming weekend, I have a lot of flexibility to "test" some options if someone can claim such a thing

Performance wise it won't matter much what kind of partitioning you use. Just make sure that the files you want to access the fastest are at the beginning of the drive, and the ones you don't care about are at the end.

Also, you should add in a 16GB partition between #1 and #2 for your page file and hiberfil.sys (for hibernation). Sure with 8GB RAM you won't use it much, but better safe than sorry. And having a separate partition for these files ensures no fragmentation, and positioning it between the OS and the Apps will keep their access time to a minimum, as it can be reached quickly from either end. And the closer hiberfil.sys is to the beginning of the drive, the faster you enter and leave hibernation. Besides, what's 16GB out of 1000?

Okay so why do I need 16GB for this partition again? yeah its only 16GB but I am not one to waste.
The way I see it, I have always run a 1GB PF as to force things into RAM. the 1GB is a safety net for programs that 100% must have it. Ive tested 1,2,4,8 GB sizes and the result was no PF gives fastest boot times and load times in games only, 1GB seems to have the best real-world performance for MS word and FF3 and the like, anything past 2GB made the system feel slow. I gave 10 days between each test to allow superfetch to adjust as it seemed to be reset every time I changed PF size.

I personally think I would do a 2GB partition between the OS and data partition: 1GB for PF and additional space for buffering..


Also, what determines the location of a partition? is it just the order I create them in? I am utterly confused about how that works

Well the reason I said 16GB was 8GB for the pagefile and 8GB for the hibernation file. So if you want just a 1GB pagefile then you should create a 9GB partition (plus a few MB extra as a safety net). You can live without much of a pagefile, but there's no avoiding a big hibernation file. It has to be able to save all your ram weather you like it or not!

And nah its not just the order. Well, if you have a completely blank HD (even a blank MBR) then yeah it will do it in order. But to be safe use GPARTED, not the windows installer. The way you see it in the graphical interface is exactly the way it is positioned on the hard drive.

It still a valid way to avoid a big hibernation file.

I dont bother with hibernation on my desktop man...with my Vista I disable most of the garbage on startup so I can usually get to my desktop in about 30 seconds.. windows loading takes about 15 of that, the other 15 is waiting on BIOS to clear this and that

on my laptop I use hibernation, i might format and partition this way because lately its been taking longer and longer to start up from hibernation and shut-down state
