2]确保(Make)TRIM命令正在运行
如果TRIM命令未运行， SSD驱动器将运行缓慢。按照以下步骤确保 TRIM 已启用。
- 单击“开始”(Start’)并键入“ cmd”
- 右键单击“命令提示符”(Command Prompt’)并单击“以管理员身份打开”(Open as Administrator’)
- 复制并粘贴命令——“ fsutil 行为查询 DisableDeleteNotify”(fsutil behavior query DisableDeleteNotify”)
- 按“输入”(Enter’)
- 现在，如果结果为“ 0 ”，则表示TRIM已启用，如果结果为“ 1 ”，则表示已禁用。如果您在结果中得到“ 1(1) ”，请继续下一步。
- 键入fsutil 行为集 DisableDeleteNotify 0(fsutil behavior set DisableDeleteNotify 0)
- 点击输入。
这将在您的系统上启用TRIM命令。
注意(NOTE)：如果您现在在Windows 11中运行该命令，您将看到它显示如下 - 但它的含义相同。
值0已被描述为允许将 TRIM 操作发送到存储设备(Allows TRIM operations to be sent to the storage device)。
3]启用AHCI模式
高级主机控制器接口(Advanced Host Controller Interface)( AHCI ) 指定串行 ATA(Serial ATA) ( SATA ) 主机控制器在其主板芯片组中以非特定于实现方式的操作。该规范描述了一种系统内存结构，供计算机硬件供应商在主机系统内存和附加存储设备之间交换数据。此模式对于您充分利用SSD至关重要；如果未启用，您的SSD将运行缓慢。您可以在 Windows 10中轻松启用 AHCI。
4]选择Power高性能模式
这是一个快速的潜在修复。请按照以下步骤尝试更改为Power高性能模式：
1]在“开始”(Start’)菜单中搜索“电源和睡眠设置”(Power & Sleep settings’)
2]向下滚动(Scroll)右侧选项，然后单击“相关设置(related settings’)”下的“其他电源设置”(Additional power settings’)
3]在“电源选项”(Power Options’)窗口中，单击左侧菜单上的“创建电源计划”(Create a power plan’)

就像其他硬件一样，SSD制造商也会定期为SSD(SSDs)发布补丁和更新。SSD(SSDs)的固件对于平稳高效地运行至关重要，因此请记住不断检查固件更新。要更新您的SSD，请按照下列步骤操作：
- 按‘Win + R ”键打开“运行”(Run’)对话框。
- 在“运行”对话框中，输入“ devmgmt.msc ”
- 点击“输入”
- 在“设备管理器(Device Manager)”窗口中找到“磁盘驱动器(Disk drives)”并单击箭头并展开它。
- 右键单击 SSD，然后单击“更新驱动程序(Update Drivers)”
- 系统将提示您选择“您要如何搜索驱动程序？” (How do you want to search for drivers?’ )点击“自动搜索驱动程序”。(‘Search automatically for drivers’.)
Windows 现在将搜索适用于您的SSD的任何新更新并安装它们。一旦过程完成。检查您的问题是否已解决。
7]配置正确的引导顺序
SSD驱动器速度慢的另一个原因可能是引导顺序配置错误。如果优先考虑硬盘而不是SSD，计算机将运行缓慢。本Windows指南将展示如何启动到Windows 10固件设置 ( UEFI/BIOS )，并轻松更改启动顺序(change the boot order easily)。
8]检查您的SATA端口
如今，大多数主板都包含SATA 3Gbps/ SATA 6Gbps端口。端口的速度在很大程度上取决于 SSD 的性能。SATA 端口(SATA Port)可能很难识别，因此您必须参考主板手册才能正确确定它。通常，在英特尔(Intel)芯片组上制造的主板包含一个英特尔 SATA(Intel SATA)控制器。该控制器特别具有最高速度。因此，引导设备应该只连接到这个设备。
9]检查您的SATA电缆
导致SSD(SSD)性能不佳的另一个原因是质量差或SATA电缆有缺陷。因此，请检查以确认数据线状态是否良好，同时建议您只从知名制造商处购买SATA数据线。(SATA)
除了上述之外，您还可以尝试增加 RAM 或完整格式化SSD -这些技巧还有助于修复Windows 10上缓慢的(Windows 10)SSD读取或写入速度。
由于各种原因，您的SSD可能会变慢，但当这种情况发生时立即采取行动并拯救您的数据，因为SSD随时可能损坏，您可能会丢失所有有价值的数据。

Fix Slow SSD Read Or Write Speed On Windows 11/10
Many users arе slowly migrating from using HDDs to SSDs, the reason is simple – SSDs start up a computer quickly. But slow SSD read/wrіte speed problеms are very much real. If your device containѕ a Ѕolid-State Drive (SЅD), уou perhaps noticed that as it fills up, its performance falls dramatically. You would notice that oрening applications and copying files will take longer than usual, and sometimeѕ this will also cause freezing issues making your device toυgher to use.
SSD is the short-form for a solid-state drive; it is a storage device that gained immense popularity in recent times. It adopts integrated circuit assemblies to help people store data for good. Yet, several reasons can be responsible for slow SSD read or write speed on Windows 10 or other operating systems, these include:
- Low Space
- TRIM command is disabled or doesn’t exist
- AHCI mode is disabled
- The Boot sequence is incorrectly configured
- Computer or SSD is infected with viruses
- BIOS/firmware is outdated
- Something is wrong with the SATA port or cable
- Low RAM.
Among others, these were the most common reasons for the declination in the speed and performance of the SSD.
TIP: Test your Read-Write speeds using CrystalDiskMark or Parkdale.
Slow SSD Read or Write Speed on Windows 11/10
It can be hard to pinpoint the exact problem that your system could be facing, we will be listing down some tips that will hopefully get your SSD up and running again.
- Free up space to improve performance
- Make sure the TRIM command is running
- Enable AHCI mode
- Choose high-performance mode
- Optimize your SSD
- Update Firmware of the SSD
- Configure correct Boot order
- Check your SATA port
- Check your SATA cable.
Let us look at these solutions in more detail.
1] Free up space to improve performance
The less space on your SSD, the slower it will perform. If your SSD is at 90 percent capacity or higher, and you notice some performance issues, at this point you should first try and clear up some space. The most obvious thing that you can try is to start deleting unnecessary files and folders from SSD that may be occupying the space.
Another idea that works is to disable hibernation, as this could free up a lot of disk space for you. Follow these steps:
- Open ‘Command Prompt’ from ‘Windows Search’.
- Type ‘cmd’
- Right-click on the top search result and choose command prompt with administrative rights i.e., select the option ‘Run as administrator’
- Type ‘powercfg -h off’
- Hit ‘Enter’
Once you followed the steps mentioned above to clear off some space in your SSD. Check if there have been any improvements in the SSD read/write speed. If it didn’t work, move on to the next solution.

2] Make sure the TRIM command is running
An SSD drive will run slow if the TRIM command is not running. Follow these steps to make sure the TRIM is enabled.
- Click ‘Start’ and type ‘cmd’
- Right-click ‘Command Prompt’ and hit ‘Open as Administrator’
- Copy and paste the command – “fsutil behavior query DisableDeleteNotify”
- Press ‘Enter’
- Now, if you get ‘0’ as the result, it means TRIM is enabled and if you get ‘1’ it means disabled. Move on to the next step if you get ‘1’ in the result.
- Type fsutil behavior set DisableDeleteNotify 0
- Hit Enter.
This will enable TRIM command on your system.
NOTE: If you run the command now in Windows 11, you will see it displayed as follows – but it means the same thing.
The value 0 has been described as Allows TRIM operations to be sent to the storage device.
3] Enable AHCI mode
The Advanced Host Controller Interface (AHCI) specifies the operation of Serial ATA (SATA) host controllers in a non-implementation-specific manner in its motherboard chipsets. The specification describes a system memory structure for computer hardware vendors to exchange data between host system memory and attached storage devices. This mode is very crucial for you to get the best out of the SSD; if it’s not enabled, your SSD will run slow. You can easily enable AHCI in Windows 10.
4] Choose the Power high-performance mode
This is a quick potential fix. Try changing to the Power high-performance mode by following the steps below:
1] Search for ‘Power & Sleep settings’ in the ‘Start’ menu
2] Scroll down the right-side options and click on ‘Additional power settings’ under ‘related settings’
3] In the ‘Power Options’ window click on ‘Create a power plan’ appearing on the left-side menu
4] Now select ‘High Performance’ and click ‘Next’
In Balanced Power Plan, your SSD doesn’t receive the full power it needs to run at its best capacity, on the other hand, the High-performance plan favors performance.

5] Optimize your SSD
After some time of using an SSD, especially after installing many applications, it is recommended to optimize SSD. Follow these steps:
- Search for ‘Defrag’ in the ‘Start menu’
- Select Defragment and Optimize Drive
- Select the SSD drive and click ‘Optimize’
Optimizing it from time to time helps bring it back to its original state.

6] Update Firmware of the SSD
Just like other hardware, SSD manufacturers release patches and updates periodically for SSDs too. The firmware of SSDs is essential for running them smoothly and efficiently, so remember to keep checking for a firmware update. To update your SSD, follow these steps:
- Press ‘Win + R’ keys to open the ‘Run’ dialog box.
- In the ‘Run’ dialog, type ‘devmgmt.msc’
- Hit ‘Enter’
- In the ‘Device Manager’ windows locate ‘Disk drives’ and click on the arrow and expand it.
- Right-click on the SSD and click ‘Update Drivers’
- You will be prompted for options on ‘How do you want to search for drivers?’ Click on ‘Search automatically for drivers’.
Windows will now search for any new updates available for your SSD and install them. Once the process is completed. check if your issue is resolved.
7] Configure correct Boot order
Another reason an SSD drive is slow could be that the boot sequence is wrongly configured. If the first priority is given to the hard drive, instead of SSD, the computer will run slow. This Windows guide will show how you can boot into Windows 10 firmware settings (UEFI/BIOS), and change the boot order easily.
8] Check your SATA port
These days most motherboards contain SATA 3Gbps/ SATA 6Gbps ports. The speed of the port stands heavily on the SSD’s performance. It can be difficult to identify the SATA Port, hence you must refer to the motherboard’s manual to correctly determine it. Typically, motherboards made on Intel chipsets contain an Intel SATA controller. This controller specifically has the highest speed. So, the boot device should be connected to this one only.
9] Check your SATA cable
One more reason contributing to a poor SSD performance is poor quality or defective SATA cable. So, have a check to confirm if the state of the cable is fine, also it is advised you purchase a SATA cable only from a well-known manufacturer.
Along with the above, you could try increasing your RAM or have a complete format of your SSD – these tricks also help in fixing slow SSD read or write speed on Windows 10.
Your SSD can become slow for various reasons, but when that happens act immediately and rescue your data because the SSD may corrupt at any time and you may lose all your valuable data.
