hdtune highlights

Read S.M.A.R.T. data and predict potential hard disk failures (such as bad sectors, abnormal temperature, read and write errors).

Performance benchmarks:

Test read and write speed (continuous/random), access time, burst rate, and generate intuitive graphs.

Disk scan:

Quickly detect bad sectors and support quick scan and full scan modes.

File benchmark:

Simulate the read and write performance under different file sizes and evaluate the 4K random speed of SSD.

AAM/APM management:

Adjust the noise and power consumption of mechanical hard drives (requires hard drive support).

hdtune features

Supports Windows XP to Windows 11 operating systems, suitable for mechanical hard disks (HDD) and solid state drives (SSD), including NVMe SSD.

‌Friendly interface‌

It provides an intuitive graphical interface, simplifies the operation process, and allows users to get started quickly.

‌Functional integration‌

Integrate hard disk transfer rate detection, health status detection, temperature detection, disk surface scanning and other functions into one, avoiding the tedious use of multiple tools.

‌Green and portable‌

A green version is provided, which can be used without installation, which is convenient and fast.

hdtune function

Through SMART (Self-Monitoring, Analysis and Reporting Technology), various parameters of the hard drive, such as temperature, remaining life, error rate, etc., are monitored in real time, and the status is marked by color (green normal, yellow warning, red critical).

Provides key indicator data, such as cumulative power-on time, number of bad sectors mapped sectors, etc., to help users predict the risk of hard drive failure.

‌Performance Testing and Analysis‌

‌Read and write speed test‌: Supports sequential read and write, random read and write (IOPS) and cache tests, and generates detailed speed curves.

‌Benchmark Test‌: Users can customize the test range and mode (accurate or fast) to evaluate the performance of the hard drive in different scenarios.

‌Bad sector scanning and data security‌

‌Surface Scan‌: Supports partial or full scan, marks abnormal areas (green normal, red bad sectors), and generates reports.

‌Data erasure‌: Provides a variety of erasure algorithms to ensure that data cannot be recovered and meets data security requirements.

‌Temperature and Noise Monitoring‌

Real-time display of hard drive temperature and generation of temperature curves to help users optimize heat dissipation.

Adjust hard drive noise and performance balance through AAM (Automatic Sound Management), suitable for noise-sensitive environments.

‌Advanced Features‌

‌Folder Space Analysis‌: Scan disk usage, identify large files and folders, and free up storage space.

‌Command line support‌: Can be integrated into scripts, suitable for batch testing or automated operation and maintenance.

hdtune FAQ

Possible reasons:

The test file size is set too small (for example, only 1MB files are tested, which cannot reflect the continuous reading and writing performance of large files).

The hard disk is severely fragmented or background programs occupy resources.

Solution:

Adjust test parameters:

In the "Benchmarks" tab, set the "Test Size" to 1000MB or larger (2000MB recommended for SSDs).

Optimize the test environment:

Close background programs such as anti-virus software and browsers.

Defragment the mechanical hard drive (right-click C drive → "Properties" → "Tools" → "Optimize").
