For a better understanding about data disks, you have to take the following key points into consideration:
- Adding more data disks increases the IOPs, and throughput, especially if you are using stripping
- Do not use Full Format because that will fill the disk clusters with OS, which means the disk will appear to be filled with data, and as a result, you will have to pay for the whole disk, whether you use it partially, or completely
- Trimming is supported for at least Windows Server 2012/ Windows 8 for Windows-based VMs
