Microsoft’s BitLocker software program encryption of for SSDs, which is activated by default in Home windows 11 Professional, causes an enormous discount within the efficiency of storage drives. TomsHardware performed intensive exams of the function and found that the velocity of SSDs might be diminished by as much as 45 %, relying on the appliance.
That’s as a result of with software-based BitLocker encryption, the processor is continually busy encrypting and decrypting the information on the SSD throughout all write and skim processes, which has an impression on the efficiency of the system.
Many SSDs now assist hardware-based encryption, by which all decryption and encryption processes are dealt with instantly by the SSDs. Home windows 11 Professional nonetheless prompts BitLocker’s software-based encryption throughout set up with out providing you with the power to forestall it.
Microsoft in all probability determined to do that as a result of it doesn’t have full management over the code for hardware-based encryption, as that’s managed by the SSD producers. Some time again, there have been incidents the place vulnerabilities have been found in SSD {hardware} encryption code that needed to be mounted by the producers. So Microsoft appears to choose to rely by itself resolution right here.
Home windows 11 Residence just isn’t affected as a result of it doesn’t assist BitLocker encryption. That’s a disgrace, as a result of Home windows 11 gained’t be absolutely safe till everybody has BitLocker encryption — although as this “drawback” exhibits, the specifics matter.
