Some customer noticed that the system seems to behave slowly. What can we do to improve the system performance?

Root Cause:

In one instance, we have seen customers that have not fully optimized their disk to cater for high volume processing. This article is to demonstrate one tested method of making use of the striped disk to achieve better I/O processing time.


Step 1: In the following example, we will add 2 physical disks in Windows 2012 R2 operating system. We will configure them using diskmgmt.msc. It will first ask you to initialize the new disks and give a choice of MBR or GPT. Make sure that MBR is selected and click OK.

Step 2:

Right click on one of the mounted disks and click ‘New Striped Volume’

Step 3:

A wizard will pop up, click Next

Step 4:

The first drive that you right clicked on will show up in the right box. Select a drive on the left that you want to add to the striped disk and click add. You can then click add for each highlighted that you want to add to the striped disk. Click Next.

Step 5:

Select a drive letter and click Next.

Step 6:

Select ‘Format this volume with the following settings:, enter your Volume Label of choice, use the file system NTFS, and the Default Allocation unit size. Select Perform a quick format, click Next.

Step 7:

Click Finish.

Step 8:

You will be prompt to convert the disk from normal to dynamic. Click Yes to continue


It will normally take less than a minute and they will be ready to use and will appear as a single drive in Windows Explorer.

Once the drive becomes available, you can start using it as your network shared folder location.

Please note that there is a 2 terabytes disk limitation using NTFS. For more information, kindly refer to this Microsoft Article (
