Quick Navigation :

To boost the overall performance of a computer, aside from a good CPU and memory chip, hard drive also plays an important role.

If your computer hard drive is becoming slow, you may want to test its read and write speed to see if you need to change for a new one. Moreover, when you buy a new hard drive, you can also utilize top free hard drive/SSD speed test software to measure its performance to see if it’s just as the vendor said.

This post will start with a detailed guide on how to easily test hard drive, SSD, external hard drive read/write speed with the best free HDD/SSD speed test software – MiniTool Partition Wizard. You can check the 4 steps below.

How to Do Hard Drive/SSD Speed Test with MiniTool Partition Wizard Free

MiniTool Partition Wizard is a 100% clean and free hard drive speed test tool which is compatible with Windows 10/8/7. You can use it to test read and write performance of almost all storage devices, including computer internal hard drives, external hard disk drives, SSDs, USB drives, and more.

This software has free version, pro version, and several higher versions. To perform the disk benchmark, you can only use its free version.

Click the button below to download and install MiniTool Partition Wizard free version on your Windows 10/8/7 PC. And follow the simple operations to test hard drive/SSD speed.

Free Download

1. Run HDD/SDD Speed Test Software

Open the hard disk/SSD test software for Windows 10/8/7 - MiniTool Partition Wizard. Click Disk Benchmark button on the tool bar of the main interface.

Click Disk Benchmark

2. Set HD/SSD Disk Test Parameters

Next you can select a partition on the hard drive to test its read and write speed, and then freely set the test parameters in the Disk Benchmark window.

Namely, you can set the data transfer size from 1KB to 2048KB at one time; the total amount of transferred data from 100MB to 4096MB; set Queue Number to queue up several read and write tasks on the drive; set Thread Number to use how many threads to do the hard drive speed test.

And choose a disk Test Mode like Sequential, Random, and Sequential & Random.

3. Start to Test Hard Drive Speed

Click Start to begin testing the hard drive or SSD read and write speed with the hard disk/SSD speed test software for Windows 10/8/7. Different test settings may take different time. After the hard disk/SSD speed test process is finished, it will show you an intuitive graphical table.

4. Check and Analyze the Speed Test Result

You can check the hard drive speed test result now, and compare it with standard read/write speed of hard drive to see if they differ too much.

Normally a modern 7200 RPM HDD connected with SATA delivers about 80-160 MB/s, while an SSD can read and write sequential data at about 500MB/s.

Test Hard Disk/SSD Speed and Analyze Test Result

Knowledge base:

Seq refers to sequential read and write speeds, while 4K means random read and write speeds.

Sequential reading and writing: it is mainly for measuring hard drive speed when transferring large files like copying movie videos. A high sequential read speed can also lower the loading time of large files or programs like games. It is more important for mass storage drives like external hard drives.

4K random reading and Writing: this matters more in testing hard drive speed in reading and writing random small files. It is more important for computer system drive since high 4K random read/write speed can deal with multiple tasks efficiently like smoothly running more background programs on computer.

How to Increase Hard Drive Speed in Windows (10)?

If you find your (external) hard drive runs very slow after the hard drive speed test, you may try these ways to improve your hard drive speed.

1. Scan bad sectors

If there are bad sectors on hard disk, then it will slow down the hard drive transfer speed. You can easily check whether your hard drive has bad sectors for free with MiniTool Partition Wizard disk surface test function.

Free Download

Step 1. Launch MiniTool Partition Wizard and right-click the target disk. Choose Surface Test option.

Step 2. In the Surface Test window, you can just click Start Now and this program will scan the hard drive immediately.

Step 3. After the disk testing, it will show if your hard drive has some bad sectors. If so, it will be marked red, if not, it will be marked green.

Scan Hard Drive Bad Sectors

If your hard drive has some bad sectors, you can use some professional software to bypass bad sectors, or send it to professional disk repair stores. If nothing helps, you can change a new drive.

2. Delete unnecessary files

The hard drive is very slow after doing the hard drive or SSD speed test in Windows (10).

In case the hard drive is filled up, you may clean up some unnecessary files to free up some storage space. Check how to easily check which files occupy large amount of space on your hard drive and choose to delete them with MiniTool Partition Wizard space analyzer function below.

Step 1. Double-click MiniTool Partition Wizard software icon on screen to enter into its main interface. Click Space Analyzer function. Then choose a drive and click Scan.

Step 2. When the disk scanning is completed, MiniTool Partition Wizard provides you three ways to check the files: Tree View, File View, and Folder View.

Step 3. The folders are listed in descending order. Check which folders/files occupy large storage space. You can right-click specific folder/file to open, explore it, copy its path, delete it to recycle bin, delete permanently or check its property.

Analyze Hard Drive Space and Delete Unnecessary Files

3. Perform a hard drive defragmentation

A fragmented hard drive may also be slow. Huge amount of fragmented files will slow down the hard drive read and transfer speed a lot. To defragment hard drive in Windows (10) can pull the scattered pieces of a file into single data block. Therefore, it can reduce the data access time on a hard drive.

Click Start -> Control Panel -> System and Security -> Defragment Your Hard Drive -> Click Analyze Disk (if the drive has more than 10% fragmentation, it needs to be defragmented) -> Click Defragment Disk button after the disk analysis -> Click Close button after the disk defragmentation is completed.

Perform Hard Drive Defragmentation

4. Extend C drive on computer

Hard drive speed largely influences computer’s performance. You can also extend the operating system partition on the hard drive to boost the computer speed.

Does High RPM Hard Drive Mean Fast Hard Drive Speed?

When choosing a hard drive, RPM is an important factor. RPM is short for revolutions per minute. This parameter of hard drive indicates the rotational speeds of hard disk platters. When other parameters of hard disk are the same, the faster the RPM is, the faster the hard drive read/write speed will be. You can follow the guide above to test hard drive or SSD speed with different RPMs to verify.

Most desktop computer hard drives equip 7200 RPM. The fastest hard drive RPM can reach to 15000 RPM which can be found in enterprise drives.
