It's necessary to know how to partition a new hard drive, external HDD, or SSD in Windows 10 into several volumes. For many of us using Windows computers, typically, we have two to four hard drive partitions, such as C, D, E & F drive. We use each of them for different purposes. C drive, also known as the system drive, is for Windows OS installation and system files. The rest partitions are usually data partitions, which we may use them to store a specified type of data. The number of partitions doesn't really matter, just depends on how many you want on your computer. Partitioning 1TB hard drive in Windows 10 can be done in two ways, either with third-party disk and partition software or Disk Management.
