SSD, also known as Solid-State Drive, uses flash memory to deliver vastly superior performance and durability. It's faster and more durable than normal HDDs. With these advantages, SSDs are excessing traditional HDDs, becoming computer manufacturers' love.

Thus, with more PCs shipped with SSD coming on the market, how to partition SSD, making full use of an SSD, becomes a new issue. And you can address it here with the complete guide below. 

Should I Partition SSD for Windows 10 or Gaming? Help!

"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?"

Should I partition my SSD for windows 10? I want to use my SSD for gaming, is it a good idea to partition SSD? The answer is Yes.

Advantages of Partitioning SSD:

By partitioning SSD, you'll enjoy all the advantages listed below. So I recommend you to do it especially when you want to make additional partitions:

  • Easier to Back Up and Restore System
  • Better to Manage System and Personal Data
  • Protect Data from System Crash or Failure Issue
  • More Efficient to Use OS, Files
EaseUS SSD Partition Tips:
1. If you have only one disk, create at least two partitions: one is for OS, the one is for data.
2. If you have 2 or more disks, partition SSD as the OS disk and use HDD as a data disk.

In a word, the best way to protect your OS and personal data is to 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. 

For most users, SSD partitioning is not an easy task. To help you start with this task, follow the next two parts to make partitions on SSD now.

Part 1. Check The State of Your SSD

The ways to partition SSD may be different based on the state of your SSD disk. Let's check the state of your SSD first in Disk Management:

Step 1. Install SSD to your computer correctly via the connection cable.

Step 2. Restart PC, right-click "This PC/My Computer" > "Manage".

Step 3.  Click Disk Management and check the state of your SSD:

Check SSD State

  • Not Initialized: It means that you need to initialize SSD first before creating partitions on it.
  • Unallocated: It means your SSD is initialized and you can directly create partitions on it.
  • Partitioned: It means you have partitions on SSD, and you need to resize and repartition SSD.

And you can follow the complete guide in the next part to start partitioning your SSD now.

Part 2. How to Partition SSD Safely & Easily

It's not like making folders. You know, creating and resizing partitions is a hassle. Here you can follow the respective guide to partition SSD by using partition software or using Disk Management easily:

  1. #Guide 1. SSD Shows Not Initialized - Initialize SSD
  2. #Guide 2. SSD Shows Unallocated - Partition SSD & Create New Volumes
  3. #Guide 3. SSD Shows Partitioned - Resize and Partition SSD

#Guide 1. SSD Shows Not Initialized - Initialize SSD

If your SSD shows Not Initialized in Disk Management, you'll need to initialize the disk first. And then follow #Guide 2 to create new partitions on it.

Here are the steps to initialize SSD in Disk Management:

Step 1. Right-click"This PC/My Computer", click "Manage" and click "Disk Management".

Step 2. Right-click the not initialized SSD and select "Initialize SSD".

Initialize SSD

Step 3. Set "MBR" or "GPT" for SSD, and click "OK" to confirm.

What partition style should I use for SSD? Basically, if you only want to create 1 or 2 partitions, MBR is good. But if you want to create multiple partitions or install the latest Windows 10 on SSD, choose GPT. For more information, learn MBR vs GPT

After initializing the SSD, you can follow #Guide 2 to create partitions on your SSD.

#Guide 2. SSD Shows Unallocated - One-Click to Partition SSD & Create New Volumes

If your SSD currently displays as unallocated in Disk Management, the computer will regard it as a brand new disk. To make use of it, you need to create partitions on the drive.
