Shall I Partition My SSD or Not? Help!

SSD is short for "solid-state drive." It uses flash memory to deliver vastly superior performance and durability. SSDs are faster and more durable than HDDs. Thus many people are using SSDs. Nowadays, the capacity of SSD is much larger and many users want to know whether they should partition their SSDs. Here's an example:

"Recently, I bought a Kingston 1TB SSD. And I want to replace the old HDD with it. I was thinking about partitioning it into two partitions, one with about 250GB (250GB with windows boot partition and all) and then use the rest for gaming. Shall I partition my SSD? How to do it?"

SSD partitioning has many advantages, so I recommend you to do it especially when you want to make additional partitions:

  • SSD partitioning allows you to have multiple operating systems on one computer.

It is helpful if you want to run two versions of Windows, or Windows and Linux.

  • SSD partitioning enables you to separate system and data.

You can install Windows and your various programs on the system partition and store your data such as games, documents, pictures, music, and video files to a new partition. It is the best way to avoid unexpected data loss disaster caused by system problems. 

For most users, SSD partitioning is not an easy task. It’s not like making folders. You know, creating and resizing partitions is a hassle. Here are two ways to partition SSD - using partition software or using Disk Management.

Method 1: Partition SSD with EaseUS Partition Tool 

The easiest way to partition SSD is by using third-party software. EaseUS partition tool is my suggestion. This software can create disk partitions and manage data storage space easily. In addition to disk partitioning, it has many other useful features:

  • Migrate OS to SSD/HDD
  • Convert Disk/Partitions
  • Format a Hard Drive/Partition
  • Merge partitions
  • Recover lost partitions


With this tool, you can format SSD to the various file system. Partition SSD to multiple partitions with 4K alignment, clone SSD, merge SSD partitions, etc.  Now you can directly download EaseUS Partition Master and follow the steps to partition it.

Step 2. Create a partition.

Once you have got unallocated space, you can create a partition. On the main window, right-click on the unallocated space on your hard drive, SSD or external storage device and select "Create". Set the partition size, partition label, drive letter, file system, etc. for the new partition and click "OK" to continue.

Method 2: Partition SSD with Disk Management 

This method is used to shrink the existing partition and then use the unallocated space to create a partition. If the SSD hasn’t been partitioned, you can create partitions on it directly. 

Step 1: At the start, type Disk Management and you will see a list of connected hard drives.

Step 2: Right-click one SSD partition and select "Shrink Volume". Enter the amount of space you want to shrink then click on the "Shrink" button. (This would create unallocated space.)

On the partition that is going to be operated, there might be some files being occupied by other programs.
