Windows 10 Disk Performance Review

The newly released Windows 10 operating system provides a large number of interesting features making it one of the most anticipated versions of the world's most popular family of operating systems. Besides new features and a refreshed user interface, the newly released operating system promises more performance on older hardware platforms allowing users to upgrade to Windows 10 without purchasing new computers.

Windows 10 Normalized Disk Performance Index

One of the most important performance aspects of an operating system is the disk performance, which impacts almost all computer operations including the computer boot time, programs start times, documents load times, etc. The purpose of this performance review is to compare the performance of Windows 10 disk I/O operations with a number of older operating systems including Windows 8, Windows 7 and Windows Vista.

Test Server Configuration
  • 4-Core Intel CPU
  • 16 GB of system memory
  • SSD disk for the operating system
  • SSD disk for disk performance tests
  • Intel Gigabit Ethernet network card
Tested Operating Systems
  • Windows 10 64-Bit
  • Windows 8 64-Bit
  • Windows 7 64-Bit
  • Windows Vista 64-Bit

In order to measure the disk performance of Windows 10 and compare it to the performance of Windows 8, Windows 7 and Windows Vista, we have tested all the four operating systems on the same hardware platform and performed the following tests:

  • Small Files Copy Performance Test
  • Medium-Sized Files Copy Performance Test
  • Large Files Copy Performance Test
  • Disk Space Analysis Performance Test
  • File Classification Performance Test
  • Duplicate Files Search Performance Test
  • File Search Performance Test
  • File Delete Performance Test

All tests were performed using DiskBoss v5.9.18 (64-Bit), which is capable of performing different types of file copy, file synchronization, disk space analysis, file classification, duplicate files search, file search and file delete operations. All the tested operating systems were benchmarked using exactly the same set of files, in the same order and on the same hardware platform.

Windows 10 vs. Windows 8 Disk Performance

In order to easily compare different types of disk performance results, all results were normalized and an averaged, normalized disk performance index has been calculated for each tested operating system. As it is clear from the disk performance results, Windows 10 provides significantly better disk performance results in almost all types of tests.

Windows 10 vs. Windows 7 Disk Performance

For example, in our specific test configuration, Windows 10 disk I/O operations are 13.14% faster than Windows 8, 21.76% faster than Windows 7 and 40.96% faster than Windows Vista. Windows 10 managed to improve the disk performance in almost all types of disk I/O operations, but unfortunately there is a slight performance degradation in disk space analysis and file search operations.

Windows 10 vs. Windows Vista Disk Performance

In all types of file copy operations, Windows 10 delivers significantly better performance results. On average, Windows 10 is capable of copying files 25.55% faster than Windows 8, 46.59% faster than Windows 7 and 58.97% faster than Windows Vista.

Windows 10 Average File Copy Performance

On the other hand, in disk space analysis and file search operations, Windows 10 delivers slightly degraded performance results, which are approximately 10% slower than the Windows 8, Windows 7 and Windows Vista operating systems.

Windows 10 File Search Performance

In file delete operations, Windows 10 again manages to significantly improve the performance results and delivers a 40.05% improvement over Windows 8, 44.95% improvement over Windows 7 and a 46.14% improvement over Windows Vista.
