The new system Windows 11 has a lot of cool features for users, but there's a problem as well – the SSD is slow. This is even apparent after an upgrade or update. It's important to boost overall performance, including the booting speed. Today, we'll share 7 solutions to fix the Windows 11 NVMe slow problem. Before we get into that, let's learn a bit about NVMe SSDs.

Overview of NVMe SSD

NVMe, or Non-Volatile Memory Host Controller Interface Specification, is a protocol for PCIe bus, creating a direct connection for storage drives. This enhances read-write speeds and reduces program loading times by allowing SSDs to connect directly to the CPU. NVMe is tailored for SSDs, providing faster I/O operations and increased data transfer, making it widely used for personal and business purposes.

With the transition from traditional HDD form factors to 2.5" SSDs and the introduction of M.2 slots, combining NVMe SSDs with M.2 slots (especially setting the M.2 NVMe SSD as a boot drive) can bring a compact, high-speed solution for easy and fast installations, program executions, and loading times.

According to expectations, the NVMe SSD should offer a lightning-fast experience. But why is your Windows 11 NVMe slow? In the next section, we will share the reasons along with corresponding solutions.

Reasons and fixes for Windows 11 NVMe drive slow

Why is your Windows 11 NVMe SSD slow, especially after an upgrade and update? It could be because you haven't taken optimized measures, like downloading the driver or the latest Microsoft updates. Other reasons might attribute to the SSD itself. For instance, the NVMe SSD could be in bad condition, not running 4K Alignment, or being too small or old. Read this part patiently. You can effectively solve the slow NVMe performance issue with abundant solutions.

Reason 1. Not adopt optimized measures to improve the NVMe performance

Fix 1. Download NVMe driver to relieve SSD drive slow performance
NVMe driver usually refers to a program launched by the manufacturers. Samsung as a technology giant, has its own Samsung NVMe driver is a typical program for its SSD performance optimization. Generally, the performance can get a more pronounced enhancement than before. Now, let’s see how to download and install the useful program.

Notice: Please download the driver installation files from the Samsung official website.

Step 1. Decompress the files and then open them.

Note: Please enter BIOS to change the settings before installation. Or the drive may fail to install: BIOS > System Configuration > SATA Configuration > Choose AHCI
※ If you don't know how to enter BIOS in Windows 11, here's a guide.

Fix 2. Update Windows 11 KB5007262
As noticed by Microsoft, a specific update has been launched to address SSD drive slow performance, KB5007262. If your Windows 11 NVMe is slow, trying this method can be helpful.

Step 1. Hit the “Win+I” combination to enter “Settings”, go to “Windows Update” on the left pane, then click it.

Step 2. Click “Check for Updates”. If the KB5007262 update it is available, you can click “Download now’’. Or manually download it on the Microsoft official website if this option is not available.

Step 3. Select “Restart now” after the installation process finishes.

Reason 2. The NVMe SSD is in bad condition

Fix 1. Check Windows 11 NVMe SSD health
If you download the driver or receive the latest update, but the slow NVMe performance still isn't relieved, it's better to check whether the SSD is in a healthy condition or not. AOMEI Partition Assistant Professional is a comprehensive and versatile disk manager designed for Windows 11/10/8/7. It provides numerous options to easily address various computer problems based on your specific situations.

Let's see how to use this all-in-one software to effectively fix slow NVMe performance problem.

Tip:
✍ The 3 different states mean you need to take various measures to address your NVMe SSD. Especially if there is a "Bad" notice, it's advisable to back up important data in advance to avoid unexpected data loss.

Fix 2. Monitor NVMe SSD speed
Besides checking the SSD's health, testing the disk speed is also necessary if your NVMe drive is slow. A full C drive, high CPU usage, or over-consumed memory usage will directly affect the read and write speed of the SSD.

Regularly testing the disk speed via AOMEI Partition Assistant Professional is a good habit for monitoring your SSD condition. This software can offer you a comprehensive analysis of your disk speed data.

Step 1. Enter the main interface and click the SSD, click the "Test" button at the top of the interface, and then “Disk Speed Test”.

Reason 3. The NVMe SSD does not run the 4K Alignment

Fix 1. Use 4K Alignment to improve NVMe performance
4K alignment can align the SSD physical storage space to a hard drive partition, which can process the data quickly and effectively all the more. If you are not run 4K alignment, the read and write time will be prolonged, causing SSD drive slow performance. You can check the SSD partition alignment first, then follow the tutorial to perform the 4K alignment.

Step 1. Open the installed AOMEI Partition Assistant and then choose a partition from the SSD.

Step 2. Right-click it and choose “Advanced” > “ Partition Alignment

Step 3. You can see a mini windows pop-up. Select a partition sector to align (Please choose “4096 Sector” to achieve 4K Alignment, or you can select others in light of your needs).

Step 4. After the operation, click “OK” and back to the main interface to commit the operations with hitting the “Apply” button.apply alignment

Reason 4. The original SSD is small or old

Fix 1. Migrate OS to a faster and larger SSD
Using an SSD for an extended period affects its performance due to accumulated data. This data buildup can significantly slow down Windows 11, especially for users with smaller SSDs, or those involved in tasks like video editing or gaming.

To enhance SSD performance, it's advisable to upgrade to a larger or faster SSD, such as the M.2 NVMe SSD mentioned earlier. While changing to a new SSD usually requires a system reinstallation, AOMEI Partition Assistant Professional offers a convenient solution.

You can use the "Migrate OS to SSD" function to effortlessly transfer the entire operating system and related partitions to the new disk without reinstalling. Alternatively, the Disk Clone Wizard allows you to clone to a larger and faster SSD, efficiently moving all necessary data according to your needs.

Note: Please back up the data on the SSD beforehand. In the process of migrating OS, all the data will be deleted.

Step 1. Launch the installed AOMEI Partition Assistant, click the "Clone" option at the top of the main interface, and choose “Migrate OS”. Then you can see an introduction, read it, and choose “Next”.

Step 2. In the target disk, select an unallocated space as the target location and click “Next”.

Note: If the disk has no unallocated space, you can check “I want to delete all partitions on disk 2 to migrate system to the disk" and then choose "Next".

Please power down your PC and unplug the original SSD. Connect the new SSD to your computer and enter BIOS to change boot settings. Next, boot the computer from the SSD.

Fix 2. Securely erase NVMe SSD to cope with slow NVMe performance
Even if the NVMe SSD is advanced enough, it still belongs to the sort of hard drive. With continuously using, total number of TMB (Terabytes Written) over time, and DWPD (Drive Writes per day), the SSD lifespan and performance will be heavily affected, causing the NVMe drive slow. In usual cases, some users will use an SSD Error Check tool to monitor the drive and then erase data to reset it to the factory default performance if needed.

However, people who pay attention to the secure erasing SSD function of Samsung or Intel will know there is a brand limitation—they only support their own brands. But AOMEI Partition Assistant Professional can break it. It has no brand requirements and can securely erase all the data on no matter SSD, HDD, USB, or SD card.

Note: The SSD Secure Erase feature only works in Windows 7-based systems. If the system is Windows 8 or 10, you should remove the SSD and then insert it into the device running Windows 7 system.

Step 1. Launch the software. Click the SSD, click the "Wipe" option at the top of the interface, and choose  “SSD Secure Erase”.
