Partition Raid - 0 or not?

edamski · Dec 23, 2006, 07:38 PM

Hi,
I'm planing to make my windows Xp on 2x 73gb 10000 rpm seagate drive k7 ST373207LC.
I need some advice.
Total available space will exceed my need for windows.140gb a little to much.
Can I do a partition after creating raid0 and get same performance as a raid or simple I will loose raid performance dividing the drive by partition.
Second question: Swap file where should be and how to make it best and what should be the size?
Thanks in advance for your help!
Adam

1) After creating a RAID 0 setup, you can partition the 140GB drive any way you like. It will still perform the same.

2) If you only have the single RAID 0 setup in your system, it doesn't matter where you'll put the swap file, only if you had two different RAID 0 configurations or more. You can set the size to auto or manually to 3 times your RAM size.

SCSI RAID0? 10000RPM?

You're looking at your CPU being the bottleneck now, that's some serious speed son. Paging file can go anywhere and it won't really matter

The swap file should be a "static" file, that is make the lower and upper size the same. This reduces fragmentation of the file. How big depends on how much RAM you have. I set mine to be the same as the system RAM. but I have 2 GB. With less system RAM you might want the swapfile to be bigger than your RAM size. Some people set the swapfile size to 0 to save diskspace, but that is not recommended because some programs like to see the file even if they do not need to use it.

In your RAID 0 setup, it does not matter where you put the swapfile. It only matters if there are two independent disks. Thats because with two disks, one can be reading/writing to the swapfile while the other one is reading/writing to the OS/apps drive.
