SSD Slow Write Speed FAQs

With the ten fantastic solutions offered in the article, fixing the SSD’s slow write speed has become simpler and easier.

Hopefully, you can get your SSD functioning properly using the solutions offered. Check the FAQs below if you still have questions about the SSD’s slow write speed.

1. What is a good SSD write speed?

How quickly a file can be written to the drive is measured as write speed. A standard SDD could read and write at 200 — 500 MB/s; some can even get up to thousands of MB/s. So, anything above 300 MB/s is a great speed to be at.

2. Why is my disk writing so slow?

Your disk writing may be slow for several reasons, including low RAM, outdated BIOS firmware, low disk space, a virus-infected disk, and disabled TRIM command. Using a third-party tool like EaseUS Partition Master, you can quickly identify and resolve the SSD writing speed issue.

3. How do I fix slow write speed on SSD?

Check whether the SSD has enough space before fixing the slow write speed issue. Then see if your computer has the TRIM command enabled or not. You can also check the SATA connection or cable and download the latest firmware or drivers for your PC and SSD.

A Solid State Drive (SSD) can greatly slow down due to multiple reasons, as is evident with every mechanical device. However, sometimes the SSD doesn’t really slow down on its own but an issue related to an external factor is causing this to happen. Let’s take a look at the reasons and their solutions that lead to a visible slowdown in the SSD’s performance in Windows 10.

Solution 1: Disable Onboard VGA

Many users have reported that the painfully slow performance of the SSD simply vanished once they disabled the onboard VGA feature of their computer. This resulted in a decrease of the system boot-up time upto 15 seconds. Here is what you need to do.

1. Reboot your computer and open BIOS.
2. Navigate to the Advanced BIOS section.
3. Search for Onboard VGA.
4. Now select the Disable option.

Note: The exact titles for the options and the procedure to navigate as well as disable them will vary from one motherboard to another. However, with a little bit of intelligent exploration, you can easily make your way through and do the trick. Don’t worry nothing wrong will happen so long as you don’t change a value that is critical. And even if you suspect that you’ve made a change which you shouldn’t have, there is always an option to restore BIOS to its default values to bail you out on such occasions.

Solution 2: Configure Boot Sequence

Another reason the SSD drive is slow is that the bootup sequence is incorrectly configured as a hard drive on top priority means it will take a lot longer for it to fetch and loads the operating system.

1. Restart your computer and boot into BIOS.
2. Change the boot sequence of HDD and SSD. (First priority should be given to SSD).

Solution 3: Update BIOS

Another more common reason for the poor performance of a SSD in Windows is due to an outdated BIOS. To fix this issue, simply update BIOS. You can download the latest version of BIOS from the website of your computer’s manufacturer. The updated BIOS will include compatibility for new hardware, improved cache functions and other user-friendly hardware tweaks as well.

Solution 4: Check the SATA Port

Most motherboards these days have SATA 3Gbps/ SATA 6Gbps ports. The speed of the port bears heavily on the SSD’s performance. It isn’t that simple to identify the SATA Port, hence you should refer to the motherboard’s manual in order to correctly determine it. Usually, motherboards built 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. Also note that the first SATA port has the highest speed, as claimed by most technical blogs.

Solution 5: Check the SATA Cable

Another reason the SSD performance is not meeting your expectations is that the SATA cable is either defective or of a poor quality make. Therefore, be sure to always purchase a SATA cable from a well-known manufacturer.

Solution 6: AHCI Mode is Disabled

The AHCI Mode helps bring the best out of the SSD. If this mode is disabled, the computer can encounter crashes or even see the notorious blue screen of death.

To fix it, simply go to BIOS Settings, look for the OnChip SATA Type and set it to AHCI.

Solution 7: Update Firmware of the SSD

Just like any other piece of software that acts as the eyes and the minds of the hardware, the firmware of the SSD is surely not an exception. That’s why manufacturers release patches and updates on a periodic basis. Remember to keep checking for a firmware update, or else you could be toying with an eventuality as extreme as complete performance disaster.

Solution 8: TRIM Command Doesn’t Exist or is Disabled

The TRIM command is absolute for stable performance of SSD. Make sure the SSD supports TRIM and it is enabled on your Windows 10 computer.

1. Open Command Prompt as an administrator.
2. Type in fsutil behavior query DisableDeleteNotify and press Enter.
3. If you get 0 as a result, it means TRIM is already enabled, but if you get a 1 it isn’t.
4. Enable TRIM in by executing the following command:
   fsutil behavior set DisableDeleteNotify 0

Solution 9: SSD Needs Optimization

The SSD accumulates junk just like the rest of the computer. You need to optimize it from time to time to restore it to its original spick and span shape. Windows 10 enables you to do so very easily.

1. Search for Disk Cleanup in the Start menu.
2. Perform the Disk Cleanup process for the SSD to rid if of all the junk.
3. Now search for defrag and open Defragment and Optimize Drives.
4. Perform defragmentation for the SSD drive by selecting it and clicking the Optimize button.

Solution 10: The SSD Is Almost Full

As a rule of thumb, the SSD needs to be at least 20 percent empty so as to perform at optimal speeds. Unfortunately, most users do not know about this fact and they keep on piling their personal data (in addition to the OS) on the same SSD, which literally bogs it down big time. So be sure to always create a separate partition for the OS and don’t save anything else on it come what may.

Solution 11: Go For the High Power Plan

Most of us keep our computer/ laptop at Balanced Power. The setting is easy to change and can be adjusted by typing in Power in the Search area of Windows 10 taskbar. Though the SSD doesn’t actually run fast due to the High Power plan, it is strongly suggested to select this plan if there are other devices sharing power such as the GPUs.

Solution 12: Format the SSD

If you’re using a pre-used SSD for installing the OS, it will perform a lot slower than what you’d expect from it. In such a case, format the SSD before you begin the installation.

Right-click the Solid State Drive (SSD) and select Format, or type in format /q in Command Prompt and execute this command.

Solution 13: RAM is Low

Quite possibly, it’s the RAM rather than the SSD which is causing the trouble. The RAM might have ‘fallen’ to a very low level which would have led to a decrease in the cache size and adversely impacted the SSD’s performance.

Remember to add a minimum of 4GB of RAM for decent performance of the system if you plan to use Windows 10. And if you will be using heavy duty software programs, then 8GB is a must have!

Solution 14: Erase the SSD Contents

After excessive usage of the SSD, it will get slow no matter what you try. Therefore secure erase everything saved on it from time to time by backing up your data to another disk. If you do not have ‘secure erase’ feature enabled on the disk then use a third-party software to achieve the same results.
We hope these solutions helped you out with your quest for getting the most out of your SSD. Have a good day!

People choose SSD mostly because it starts up a computer quickly (even in a few seconds). However, problems may occur and slow down the speed of SSD. This MiniTool post will discuss the issue: SSD running slow on Windows 10 and give you several easy methods to speed up your SSD and improve its performance.

SSD, short for solid-state drive, is a storage device that appears and has become popular in recent years. It adopts integrated circuit assemblies (typically flash memory) to help people store data for good. The most important reason that drives people to use SSD is its fast speed (especially fast startup).

Find Your SSD Slow on Windows 10

Nevertheless, it’s easy for you to find SSD slow on Windows 10 or other operating systems. Why does this happen? How to speed up SSD? In the following paragraphs, I will demonstrate the possible solutions to speed up a slow SSD yourself.

SSD Running Slow

By adopting an SSD, your computer should boot up and run quickly. That’s why a large number of Windows users decide to get an SSD. However, problems like SSD drive running slow may arise during usage. An important reason why your SSD drive becomes slow is the improper boot sequence – if the hard drive (not SSD) is set as the first boot device, you’ll experience an obvious decrease in the fetching and loading speed.

There are 2 situations of SSD running slow on Windows:

• SSD runs slow (SSD suddenly slow): the write performance of the solid-state drive will be decreased dramatically if you fill your SSD to near-capacity or something is wrong with the SSD. This happens frequently when the SSD is used as the second storage.
• SSD boots slow: if you’re using the SSD as the main drive, the bootup speed is supposed to be faster than that of a traditional hard drive. However, you may feel an obvious decrease in the PC boot time if the SSD gets into trouble. Besides, sometimes, users may find the computer slow after SSD installation directly.

Why Is My SSD So Slow

In this section, I will mainly focus on the possible causes of the problem – SSD slowing down.

Cause 1: filling the drive. This means the space on your SSD is just about to run out. You can go to check the capacity and used space of your SSD.

Cause 2: the TRIM command doesn’t exist or has been disabled. The TRIM command is necessary for the stable performance of an SSD; if it is disabled, you’ll get a poor-performance SSD.

Cause 3: AHCI mode is disabled. This mode is very essential for you to get the best out of the SSD; if it’s not enabled, your SSD will run slow.

Cause 4: Onboard VGA is enabled. The VGA feature will greatly affect the boot speed of your computer.

Cause 5: the boot sequence is incorrectly configured. If your computer boots from a hard drive instead of an SSD, it will run slowly.

Cause 6: the computer or SSD is infected with a virus. It is well known that a virus can make your drive and computer very slow.

Cause 7: the BIOS/firmware is outdated. If the BIOS or firmware is outdated, it will also lead to the poor performance of an SSD.

Cause 8: SATA port or cable is in trouble. If there’s something wrong with the connection port and cable, the speed will naturally be affected.

Cause 9: RAM is low. If your RAM is at a very low level, the cache size will be decreased; then, it will cause the SSD to slow down.

Cause 10: PC settings are improper. There are also chances that your SSD is in good condition but it runs slow on Windows 10 since the computer is not set to the best for SSD.

If AHCI is disabled and you want to enable it on Windows 10, here is what you need to do:

1. Go to these keys and set the value named Start to 0: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAVC\StartOverride HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride
2. Restart your computer and go to UEFI/BIOS firmware settings to enable AHCI mode. After you save and exit, restart your computer once more.

4. Disable onboard VGA

1. Restart your computer and open BIOS.
2. Navigate to the Advanced BIOS section.
3. Search for Onboard VGA.
4. Select the Disable option.

Many users have reported that once they disabled the Onboard VGA feature, they managed to solve their problem. 

5. Configure Boot order

1. Restart your computer and boot into BIOS.
2. Change the boot sequence of HDD and SSD by giving first to SSD.

Another reason why the SSD drive is slow could be that the boot sequence is incorrectly configured. If the top priority to boot up is set to hard drive, the fetch and load time for the operating system from an external source will take more time than usual.

6. Check the SATA port

Many motherboards come with two different SATA controllers: some are SATA 3Gbps, and some are SATA 6Gbps. Make sure you use SATA 6Gbps for connecting your SSD.

In this respect, you should refer to the motherboard’s manual to determine it correctly. Moreover, motherboards built on Intel chipsets come with the Intel SATA controller.

Make sure you use the Intel controller to connect your SSD, as most of the low-speed issues occur from using a non-Intel controller on a motherboard built on an Intel chipset.

Also, note that the first SATA port has the highest speed, as most tech-savvy users claim.

7. Verify the SATA cable

For better SSD performance, ensure that the cables are not defective or of poor quality and that it is well hooked up to the SATA port. Thus, a good tip is always to purchase a SATA cable from a well-known manufacturer.

8. Update your firmware

Just like every other computer hardware you own, updating the firmware on your SSD is vital as new bugs and problems get identified and resolved. If you’re using a Samsung SSD, you can find firmware updates on the Samsung Magician software.

This may also improve your SSD’s performance, drive stability, or improve compatibility with your system.

To check if you need to update the firmware, you must first identify the exact firmware on your SSD and then go on the manufacturer’s website to check if newer firmware exists for your SSD. If so, you will have to follow the instructions for updating.

9. Optimize your SSD

1. In the Start menu, search for Disk Cleanup.
2. Select the SSD drive and click OK to launch the process.
3. Delete the detected junk files.
4. In the Start menu, search for defrag and open Defragment and Optimize Drives.
5. Select the SSD drive and click the Optimize button.

The SSD accumulates junk just like the rest of your computer over time. Thus, you need to optimize it from time to time to bring it to its original shape.

In Windows 10, you can do that easily by yourself by following the instructions below or using third-party software in this respect.

10. Choose the High Power Plan

1. In the Start menu, search for power and click on Power & Sleep settings.
2. Select Additional power settings on the right side.

When you choose the Balanced Power Plan, your SSD will not receive the full power it needs to run at its best capacity, leading to slow transfer, read, and write speed.

How can I fix a slow SSD on Windows 11?

Fixing a slow SSD on Windows 11 is pretty simple. Foremost, you can try to optimize your drivers with the built-in feature.

Also, you can change your power plan to high performance to release full power for your SSD. You can also try all other fixes in this guide, as they work for Windows 10 and 11.

Do SSDs get slower as they age?

SSDs do not get slower because of age. Instead, other factors make the memory run slow.

One of them is filling your SSD to the maximum or near-maximum capacity. This reduces its write time, thereby affecting its overall performance.

Some other known factors are wrong PC settings and lack of optimization. So, you don’t have anything to worry about when your SSD age.
