Is the disk > 2 TB or on a UEFI system? → GPT Basic Disk (better than both MBR and dynamic) Systems Engineering / IT Infrastructure Document version: 1.0 Date: [Current date]
Do you need software RAID, spanning, or online expansion? → Yes → Dynamic Disk (only if Windows-only environment) mbr or dynamic disk
For modern systems, (not covered in depth here) are recommended over both MBR and dynamic disks for drives >2 TB or UEFI systems. Dynamic disks are legacy technology; software RAID and volume management are now better handled by Storage Spaces (Windows 8+/Server 2012+) or hardware RAID controllers.
