hardware offload

Microsoft’s BitLocker is getting a structural overhaul: Windows 11 will now support hardware-accelerated BitLocker, moving bulk encryption off the main CPU and sealing critical keys inside silicon to deliver major I/O and battery improvements—but the change also reshapes management, compliance...

Microsoft’s recent update to BitLocker shifts a long‑standing performance problem away from the CPU and into silicon, promising substantially lower encryption overhead on supported Windows 11 machines — but the gains, the rollout, and the operational consequences require careful examination...

Microsoft’s quietly rolled change to BitLocker — moving disk crypto out of the CPU and into dedicated silicon — promises to erase one of Windows’ longest-standing annoyances: the performance tax paid for always‑on encryption. The operating system now includes the plumbing for...

Microsoft has begun shipping a hardware‑accelerated mode for BitLocker in recent Windows 11 and Windows Server releases, letting supported SoCs and CPUs perform bulk disk encryption in silicon rather than relying entirely on the host CPU — a change Microsoft says will dramatically cut CPU usage...

Microsoft’s recent rollout of a hardware-accelerated BitLocker mode changes the long-standing trade-off between full-disk encryption and storage performance: on supported machines running the latest Windows 11 servicing updates, BitLocker can now offload AES/XTS encryption to a dedicated crypto...

Microsoft’s own documentation and recent independent testing confirm what many enthusiasts suspected: enabling BitLocker on modern NVMe-equipped Windows 11 systems can introduce measurable CPU overhead and reduce small‑block (random 4K) storage performance — but the magnitude and impact vary...
