Extra Tips - How Many Partitions Are Best for 1TB

Generally speaking, according to the file types and personal habits, a 1TB hard drive can be partitioned into 2-5 partitions. Here we recommend you to partition it into four partitions: Operating system (C drive), Program File(D drive), Personal Data (E drive), and Entertainment (F drive).

C Drive (100GB - 200GB) is the main disk that contains the operating system and the related system files. Therefore, sufficient capacity is essential for the C Drive. Usually, the operating system and related files take up 70GB space. Thus, allocate the hard drive to add about 100GB-200GB of space to C Drive.

D Drive (About 100GB) is the drive for applications. If you install too many programs on C drive, the efficiency and speed of system operation will be reduced. So it is a nice choice to create a separate partition from a 1TB hard drive to store the programs. Generally, 100GB of space for program disk is enough for most people to use.

E Drive (50GB-100GB) is mainly designed for personal files. You can save vital personal files, including office business files, study material, private videos, or photos separately. It is recommended to create a separate partition for those important individual files. Generally, 50GB-100GB of space is enough.

F Drive (600-700GB) is mainly used for entertainment, such as watching movies and listening to music. These files take up lots of space. You can allocate as much space as possible.
