Windows 11’s SSD woes
Microsoft’s software encryption for SSDs, BitLocker, has been found to be slowing down SSD performance by up to 45% in Windows 11 Pro. BitLocker is enabled automatically when Windows 11 Pro is installed and set up, and is intended to increase the security of SSD-related processes.
Eager to analyze the issue, TomsHardware tested the feature and found that SSD speeds could be seriously affected when running some applications.
Apparently, this happens because the software-based BitLocker constantly prompts encryption and decryption processes with data on your SSD while your computer carries out read and write processes. So, as your computer extracts and puts away files and data from your SSD as you go about your business, each of these inward and outward actions from the SSD is coupled with an additional encryption or decryption process that kicks off automatically every time.
A pcwelt.de article (translated by PCWorld) points the finger at Windows 11 developers including the encryption software as part of the installation process of Windows 11 Pro. According to pcwelt.de, many modern SSDs have their own built-in hardware-based encryption processes, and that results in all decryption and encryption processes being handled by SSD itself. Regardless, Bitlocker is activated when Windows 11 Pro is set up without giving users the option to opt-out or disable it.What is the heart of the problem and does it affect you?
It’s speculated that Microsoft insists on doing this because if it doesn’t, then it must give up control of encryption to SSD manufacturers. This means that Microsoft would have to depend on these SSD manufacturers to manage such a vital feature for Windows 11 Pro users, and, in recent years, there have been vulnerability issues in the hardware encryption code created by the SSD manufacturers.
