Before we get started, let's understand the factors that make Seagate external hard drive slow.

Why Is My Seagate External Hard Drive Slow?

A Seagate external hard drive is slow in two ways: First, the Seagate external hard drive becomes slow to respond or unresponsive in transferring files. Second, the Seagate External Hard Drive has a slow read/write speed. Various reasons can cause both conditions, but most of these have some commonalities. The following are some of the main causes of slow write speeds or slow transfer speeds on Seagate external hard drives:

• There is a lot of fragmentation on the Seagate external drive, so it takes longer to retrieve the scattered files.
• There are a lot of bad sectors on Seagate external drives, which can cause the drive to slow down in transfer speeds or stop working altogether.
• Faulty cables or outdated drivers can break the connection between the computer and the external hard drive.
• The Seagate external hard drive is too slow and has no free space.

If there is no problem with the cable, please continue to try other fixes.

Solution 2. Test External Hard Drive Speed

By checking the drive's speed, you can identify the problem more precisely. You can compare it with its normal speed to see if it is getting slower, and EaseUS Partition Master can help you test the hard drive's read and write speed. The tool provides a user-friendly interface to help you manage the drive.

Download this hard drive benchmark tool and run the speed test on Windows:

Step 1. Launch EaseUS Partition Master. And click the download button to activate the "DiskMark" feature under the "Discovery" section.

Step 2. Click on the drop-down box to choose the target drive, test data, and block size.

Step 3. Once everything is configured, click "Start" to begin the disk test. Then, you can see the Sequential or Random read/write speed, I/O, and Delay data.

The Seagate external drive should be close to its advertised speed. If it does slow down, let's explore the possible causes and try to fix it.

Write caching improves performance by using writes collected by volatile memory. Caching these commands allows the computer to temporarily save them until they are written to an external storage device.

Step 1. Open Device Manager and expand Disk Drives.

Step 2. Right-click on the target drive and click Properties.

Step 3. Under the Policies tab, check the Better Performance box.

Step 4. Check Enable write caching on the device.

Solution 7. Free Up Space on External Hard Drive

Running out of disk space can slow down the transfer rate of your hard drive. You can free up disk space in various ways, such as deleting extra files and applications, cleaning up large files, extending partitions, etc. For more details on how to free up space on external drives, you can click on the following link:

If the hard drive is connected to some insecure machine, viruses may infect it. This may also cause it to slow down its response time. So you'd better have a tool to protect your device from virus attacks.

Step 1. Open an anti-virus tool. (e.g., AVG)

Step 2. Scan for viruses.

Once the scan is complete, you can deal with these viruses with the help of an anti-virus tool.
