What should you check?
For Windows and games, responsiveness matters most, so an SSD should now be the primary drive. HDDs still make sense for large archives and backups.
How should you test it?
Compare capacity, price per gigabyte, interface and the free slots in your motherboard. For NVMe, verify the supported M.2 generation and lane configuration.
How should you read the result?
SSDs offer much lower access latency and faster application loading. HDDs provide more capacity for the money but are slower and contain moving parts.
What should you do next?
A practical setup is an SSD for the operating system and active apps plus a second drive for bulk storage. Keep important files in an independent backup as well.
Frequently asked questions
Do I need to install anything?
No. The guide and compatible ACC64 tests run in your browser.
Does one bad result always mean broken hardware?
Not always. Repeat the test, check the connection and settings, and if possible compare the result on another computer.
