BitLocker could be cutting the performance of SSDs almost in half in Windows 11
A new report goes some way to showing that the BitLocker security feature of Windows 11 could be massively reducing the performance of SSDs.
An investigation found that the data encryption tool, which is enabled by default in Windows 11 Pro, can slow solid state drives by as much as 45 percent. While it would be reasonable to expect a bit of a performance drop overall as the software works away encrypting and decrypting files, few people would expect the hit to be quite so significant.
