Then I was prompted to choose the partition settings, allocation unit size, volume label, quick/normal formatting and whether to enable file and folder compression (the essentials to any disk configuration, Windows RAID or not.) To choose which allocation unit size to use for your needs, consider your use of the striped volume: will you be using small files (such as allocating your disk to store temporary Internet files, as done in the proxy servers) or will you be using large files (such as video files). For small files, use small unit size (e.g. 8 KB) and for large files use large unit size (e.g. 64 KB). I left the default option unchanged and named the array creatively as “Striped Volume" (Step 5).
The wizard warns me that I am about to convert basic disks to dynamic disks (the image on the right), and I will not be able to install an operating system from any volume on the disk except the current boot volume. Aha! Let’s go back to Step 2. If you have noticed, the wizard did not list my current C: drive in the disk choosing window. This is because I could not change the running basic disk with primary partition to a dynamic disk with striped volume. If you are using software RAID, like the one we are doing, you cannot install the operating system. Or, you will have to make RAID configurations before installing the operating system (creating RAID systems before operating system installation is far beyond the purpose of this article, therefore I am skipping the subject). I click OK to continue.
When the wizard finishes, the Disk Management console shows us that the disks are online, utilized, healthy, formatted with NT File system (NTFS) and they are dynamic volumes.
