Fix 1. Try a Different SATA cable and SATA Port

Applicable to this cause: There is a problem with the SATA port or the SATA-to-USB adapter.

Due to your SATA/USB cable connection, the transfer process may be interrupted during the data migration.

If you encounter the Samsung data migration slow problem, there could be a problem with the defective SATA cable or SATA port you are using.

Step 1. First, you need to verify that the SATA/USB is properly connected.

Step 2. If they are connected correctly and the problem persists, you can easily plug the hard drive SATA cable into another motherboard port, or try another SATA cable. If that still doesn't work, then you'll have to move the USB drive to another port.

Fix 2. Check the Source and Target Samsung SSD

Applicable to this cause: Hard disk failure.

The first thing you need to do is to check if both your new and old drives are working fine. Windows provides you with a command that helps check the health of your disks, and you can run it from the Command Prompt to check both your old and new Samsung SSD drive.

Step 1. Ensure the drive you want to check is plugged-in to your computer.

Step 2. Open the Command Prompt, type the following command, and press Enter. Make sure to replace D: with the letter for your drive.

chkdsk D:

Method 2

Step 3. Command Prompt will tell you if there are any issues with your drive.

Fix 3. Check Your Target Disk Space

Applicable to this cause: Target SSD has too much data.

It is important to make sure that the drive you are copying data to has enough space available on it. If you try to copy data, say worth 100GB to an SSD that only has a capacity of 50GB, your transfer is bound to fail.

Ideally, you should only transfer data up to 75% of the total space on your target disk. This is to ensure there is some buffer space available.

Method 3

That should help fix the Samsung Data Migration slow issue with your transfer task.

Fix 4. Check the Data Capacity of the Files You’re Transferring

Applicable to this cause: Transfer large files or partitions to Samsung SSD.

You have to pay attention to your data file size and partition. If your Samsung Data Migration is slow or not responding during the transfer, make sure that you don’t move multiple large files or partitions at once. Large data transfers can cause bugs and glitches in the program. Try to transfer your files into smaller batches.

Fix 5. Update Samsung Data Migration

Applicable to this cause: The Samsung Data Migration version is not up to date.

Samsung has rolled out a new update for its data migration tool, and you should always make sure you have the latest version of the tool. If you are using an older version of the Samsung data migration software, this may be the reason for the slow Samsung data migration. You can follow the steps below to update the version of the tool to the latest version.

Step 1. Go to the Samsung official website.

Step 2. Under Data Migration, select Samsung Data Migration software for consumer SSD.

Step 3. Click the DOWNLOAD button on the right of the latest Data Migration Software package.
