Abstract: Home windows 11 Professional ships with security measures that may critically impact the efficiency of hard-state drives. Thankfully, it’s simple to show it off however some won’t know that it’s grew to become on by means of default. BitLocker encryption in Home windows 11 Professional is designed to offer protection to knowledge and make certain that it’s obtainable simplest to approved customers, but it surely comes with an overly prime penalty. To resolve the level of the affect, Tom’s {Hardware} lately examined beneath 3 situations: unencrypted (no BitLocker), software-supported BitLocker (Home windows 11 Professional default), and hardware-based BitLocker. The workforce used a 4 TB Samsung 990 Professional SSD working Home windows 11 Professional (22H2, with all patches) paired with an Intel Core i9-12900K and 32 GB of DDR4 RAM for trying out.
Within the PCMark 10 garage benchmark, the BitLocker configuration supported by means of the application led to a 20 % lower on other {hardware} varieties and no encryption. A identical drop used to be noticed within the Crystal Disk Mark random studying take a look at, and at the random writing take a look at, Tom noticed a forty five % development. In DiskBench’s 50 GB switch take a look at, the software-supported BitLocker setup used to be 11 % slower. The excellent news is that the hardware-based implementation used to be appropriate with out a encryption working in any respect. If you happen to insist on having encryption, that is the solution to pass. All take a look at effects can also be discovered on Tom’s {Hardware} for individuals who wish to be informed extra. Additionally they give an explanation for tips on how to inform when you have encryption working and tips on how to disable it if it does. In brief, if you are working Home windows 10 Professional, it will no longer paintings; when you have Home windows 11 House, it isn’t activated; when you have Home windows 11 Professional, take a look at as it could be supported. Additionally it is price noting that your mileage will range relying at the automotive and CPU you are working. A chip this is much less tough than the Intel Core i9-12900K Tom’s {hardware} used can do worse.
