Some people mistakenly take SSD defragment as the way to optimize SSD. However, it's not a right choice. If you are having this doubts about "should I defrag SSD" in your mind, follow through this page. It covers everything you need to know about SSD defragmentation, and it even includes a more secure method to optimize your SSD.

SSD Defragment - 3 Things You Should Know About

Although most experienced Windows users may have a clear viewpoint about Disk Defragment. However, some new computer users, especially SSD disk owners, may know little about SSD defragment. If it's so, check the three things about defragging SSD.

1. What Is SSD Defragmentation

Defragmentation is a process to reduce the degree of fragmentation on a storage device, re-arranging data to store into the smallest number of the contiguous region and leaving larger regions of free space for further storage. By using compaction, it would impede the return of fragmentation.

As a result, it will maximize the read and write performance on a hard drive, achieving twice or even better performance.

Although, it often happens among hard disk drives (HDDs). Windows still defragments an SSD automatically to prevent the file system from reaching its maximum tolerance of fragments.

2. What Happens If You Defrag SSD

Unlike an HDD, a solid-state drive stores data altogether in one unit, and it accesses memory randomly other than sequentially, which makes SSD faster in reading and writing data.

Due to the unique storage mechanism of SSD, it random access of a file fragment on flash memory without any delay. Therefore, defragmentation on SSD to optimize access speed is unnecessary.

If you repeately deframent SSD, it would only cause unnecessary writes to the SSD drive and shorten its service life.

3. Should You or Should You Not Defrag SSD

Should you or should you not defrag SSD? Here are some tips for you to follow:

  • For a brand new SSD disk, don't defrag it.
  • For a long term used SSD, don't defrag it too frequenlty. One or two times of defragmenation so to maximum its fragment tolerance is fairly enough.

To gain a better SSD performance, you need practical ways to optimize SSD disk. Check the next part, you will uncover SSD defrag alterantive ways for improving SSD formance.

SSD Defrag Alternative - 3 Ways to Optimize SSD

Note that if you have decided not to defrag SSDs but to optimize the disk performance, here are some ways that can help you to make it.

Method 1. 4K Alignment on SSD

4K alignment is regarded as a efficient way to align a physical partition, improving the efficiency of SSD.

SSD uses flash memory as the storage medium, and each sector is 4K bytes. AS the partition always does not start from the starting position of the physical sector, when you save a 4KB file, even the smallest one, the file will be saved in 2 different sectors. This will reduce reading and writing speed and waste disk space on SSD.

In other words, if the SSD is 4K aligned, files can be saved and read in one 4K sector, which will greatly improve the reading and writing speed on SSD. It will also save storage space on the disk.

As a result, 4K alignment is a significant way to get the best performance of SSD.

How to 4K Align SSD

You can do 4K alignment on your SSD by using a free partition manager in Windows 7/8/10. EaseUS Partition Master enables you to align the 4K sectors on your SSD with one-click without affecting the normal use.

 Windows 10 is supported

Step 1. Install and launch EaseUS Partition Master on your Windows computer.

open EaseUS Partition Master

Step 2. Select the SSD disk that you want to align, right-click it and choose "4K Alignment".

Step 3. Identify and select useless files and click "Clean up" to remove those files from your PC or laptop.

Method 3. Use Windows Drive Optimizer

As introduced at the beginning of this page, Windows built-in defragmentation feature can optimize hard drive. However, it doesn't efficiently optimize SSD.

Considering this difference, Microsoft makes a big change in this feature in Windows 8/10, etc., new operating systems. When you open the Drive Optimizer, when you choose to optimize an HDD, this tool will defrag it. When you optimize an SSD, it will send the TRIM command to notify system to erase blocks that are no longer considered for use.

Here is how to optimize SSD with drive optimizer:

Step 1. Type optimize in the Windows search box and the Defragment and Optimize Drives icon to run it.

Step 2. Select your SSD disk and click "Optimize".

Further Questions About SSD Defrag

This page answers the questions of "should you defrag or not defrag SSD" and "how to optimize SSD". However, some of you may have more questions about SSD defrag.

Here are some related questions that you may interest in. If you have the same doubts, check the answers here.

1. Should I defrag SSD before installing Windows 10?

As for a new SSD, there is no need to defrag it before installing Windows 10. No fragments exist on the drive, as a result, you don't need to defrag it. 4K alignment on SSD is more preferable.

As for a used SSD disk, installing Windows will remove everything on the target disk, you should first back up and move all useful data to another secure drive first. After the installation of Windows 10, you can try to defrag the SSD and follow methods on this page to optimize the SSD performance.

2. Should an SSD be defragmented?

For a new SSD, what you should do is to 4K align the drive. It will optimize SSD performance. For a long time used SSD, you may run disk optimize instead of fragmentation on it.

Using Windows built-in drive optimizer can help: Type optimize in Search box > Open Drive Optimize > Select SSD and click Optimize.

3. Does defrag hurt SSD?

Logically, defragmentation is a process of re-organizing disk storage unit, making data saved in contiguous rigons. It won't hurt drive. However, as SSD saves data in a different pattern, merely not many fragments will exist on the drive.

Defrag SSD is more like a re-write process to the disk, causing no good but shorten the life span of SSD.

Frequently Asked Questions

Why Choose EaseUS Partition Master?

"I've used Partition Master Professional many times to create, delete, format, move, rename, and resize partitions."PCWorld

"I love that the changes you make with EaseUS Partition Master Free aren't immediately applied to the disks. It makes it way easier to play out what will happen after you've made all the changes."Lifewire

Will the "Migrate OS" feature transfer the Windows system files only or the whole C drive?

To ensure that the migrated system will boot normally, the Migrate OS feature will transfer all the files in the system and the boot partitions. Generally, the boot partition is the C drive so the transfer will include all the files in C.

Does EaseUS Partition Master license apply to multiple computers?

The license of Partition Master Professional and Server editions can be used on 1 computer only, while that for for the Technician and Unlimited editions can be used on multiple machines.

What is the difference between EaseUS Partition Master Trial version and the Free version?

Free is for home users only, with most basic functions available such as partition resize and clone. While trial can help you understand how this product works and test what a full license can do on a business or server OS machine.

Will it cause any data loss after resizing the partition in EaseUS Partition Master?

Generally, it will not cause any data loss or boot issue by resizing a partition. However, in order to protect your data, we suggest that you backup the partition before resizing, in case of any unexpected situations such as power outages, computer hardware failures, etc. You can use EaseUS Todo Backup to backup the partition and its trial version is fully functioned for 30 days.

What should I prepare before resizing the partition?

On the partition that is going to be operated, there might be some files being occupied by other programs. To ensure a successful operation, we suggest that you close all the unnecessary software before resizing that partition. Otherwise, EaseUS Partition Master will detect the partition being locked by the other software and require a reboot to resize the partition under boot mode.
