Do SSDs Slow Down When Full?

Do SSDs get slower when full? Yes, indeed. You'll observe a slowdown in your SSD's performance as it fills up. According to Reddit and other forum users, the speed of an SSD can decrease significantly once the storage utilization exceeds 75%.

This issue does occur when you continue to write files on it or launch apps, and you'll save more time than ever. Unfortunately, your PC might freeze while you're gaming, clipping videos, writing essays, and so on.

SSD is faster than HDD. However, the optimal performance is maintained when the disk space is not fully occupied. If you're using an SSD and the existing data takes up 70% of the space, the drive will start to slow down. This is because SSDs can only write and store data in empty blocks. If a block is not available, the solid-state drive needs to erase data marked as deleted before filling it with new data. This erasure and rewriting process is one of the reasons for the drive's decreased speed.

How much slower when SSDs get full? As we test, the read speed remains as fast as ever, but the write speed becomes 40%-50% slower.

How do I fix a slow SSD issue?

1. SSD Optimization - Boost SSD Speed

One way to address SSD slowdowns is to optimize your SSD storage. Since storage capacity influences SSD performance, managing your drive space is crucial. Traditionally, a reliable third-party partition manager tool can assist in extending the space size, but it typically requires unallocated space adjacent to the target drive.

What should we do? Download the tool Partition Master. You can utilize this free disk manager to resize, shrink, delete, format, merge, and create partitions without data loss.

**1. Extend SSD Space**

< strong > Step 1. Shrink partition to free up space for extending partition. < /strong >

If the hard drive has sufficient unallocated space to extend the target partition, proceed to Step 2. If not, free up space first:

< li >In the Partition Manager section, right-click on a partition adjacent to the target partition and select "Resize/Move".< /li > < li >Drag the partition ends to free up space, ensuring there is sufficient unallocated space behind the target partition. Click "OK".< /li >

< strong >Step 2. Extend the target partition.

Right-click on the target partition you wish to extend and select "Resize/Move."

Drag the target partition handle into the unallocated space to extend the partition.

Step 3. Keep all changes.

Click the "Execute Task" button and select "Apply" to save all modifications.

When your SSD runs out of space, you can also use the Extend Second Disk feature in AOMEI Partition Assistant to expand the SSD across a second disk. If you need this, please follow this link: Extend SSD across Disk.

Step 1. DOWNLOAD and install AOMEI Partition Assistant for free, then launch it on your Windows PC.

On the suite, hover your mouse over "PC Cleaner", click the Download icon to install and launch CleanGenius.

Step 2. On CleanGenius, select "Cleanup" on the main screen, and click "Scan" to initiate scanning.

Step 3. When the scan is complete, select the unnecessary large files and click "Clean" to get rid of them.

Step 4. After CleanGenius finishes cleaning the selected files, click "Done" to complete the process.

2. Ensure AHCI Mode Is Enabled

AHCI mode is crucial for the optimal performance of an SSD. If it's disabled, your device might encounter unexpected boot errors. Hence, please ensure that AHCI is enabled.

Step 1. Right-click the Start icon and select Device Manager from the menu.

Step 2. Expand IDE ATA/ATAPI controllers.

If it says "Enabled," click it to change it. Disable - Leave it as it is.

If you're unable to locate the controller, refer to the resolved issue on Dell's community forum - Dev. manager missing "IDE ATA/ATAPI controller."

3. Check if TRIM is Enabled

Solid-state drives store data differently from HDDs. To write new data to the device, the drive must first clear the existing data. This cleaning process can take a lot of time and potentially slow down your SSD's speed. Don't worry, though; the TRIM function comes into play to automatically zero out the deleted data cells before re-writing data.

Follow the detailed tutorial to ensure that TRIM is enabled:

Step 1. Open the Windows search bar and look for "cmd." Select "Run as administrator."

Step 2. Type the command line and press Enter: fsutil behavior query disabledeletenotify.

Step 3. Next, check the command prompt to determine if TRIM is enabled on your SSD.

NTFS DisableDeleteNotify = 0 - This means "TRIM is enabled."

NTFS DisableDeleteNotify = 1 - this means "TRIM is disabled."

If your TRIM technology is not enabled, proceed to enter the command line.

Input the command: fsutil behavior set disabledeletenotify 0

Then press Enter to activate it.

4. Verify That Write Caching Is Enabled

Write Caching is essential for boosting SSD performance. However, it makes your PC susceptible to data loss in case of power failures. If you opt to proceed with enabling TRIM, follow these steps:

Step 1. Right-click the Start icon and select "Device Manager."

Step 2. Expand "Disk drives" and click on the "Properties" button.

Step 3. Select the Policies tab, then check "Enable write caching on the device."

Step 4. Click on "OK."

5. Enter BIOS and Enable AHCI Mode

Step 1. Press "Windows + R" to open the Run box, then type "msconfig" and click Enter.

Step 2. Go to the Boot tab and enable "Safe boot" under the Boot options.

Step 3. Save the changes and restart your PC.

Step 4. Enter BIOS:

Turn on the computer > Press F12, F2, or DEL to enter BIOS settings > Change the SATA mode from IDE to AHCI > Save the changes and exit.

Step 5. Restart your PC > Repeat Step 1 > Deselect "Safe Boot" under the Boot tab.
