Win11默认的Bitlocke让磁盘性能损失45%
Enabling BitLocker in Windows 11 can indeed have a significant negative impact on system performance, particularly when using software-based encryption. According to a recent analysis from Tom\'s Hardware, the performance drop can be as much as 45% for SSDs due to the additional processing required for encryption and decryption tasks performed by the CPU. This is especially evident in random read and write operations, which are critical for overall system responsiveness and performance.
In summary, while BitLocker provides essential security features, its default software implementation in Windows 11 can significantly impair SSD performance, especially in environments where high-speed data access is critical. Users should assess their need for encryption against the potential performance impact and consider switching to hardware-based encryption solutions if available.
