Microsoft may be rolling out a new feature as part of the latest Windows 11 update that will boost security measures but slow down SSD execution . We ’re talking about BitLocker , of class , a gadget encoding feature that will be plough on by default as part of theupcoming 24H2 update .

In the past times , BitLocker encoding was available only onWindows Proeditions , but the new update lower the eligibility criteria , extending encryption capabilities to a broad range of devices .

In theory , this sounds great . Who would n’t want some extra surety for their information ? Well , a key business concern with feature BitLocker on by nonpayment is its potential impact on SSD execution . Tom ’s Hardwaretested BitLocker onvarious SSDslast class and found that it can significantly sham performance . The tests shew that when BitLocker encoding is enabled , sequential read speeds could drop by up to 45 % and pen speeds by up to 40 % . Random study and pen speeds were also feign , though to a less extent .

The execution reach wide-ranging depend on the drive and workload , but overall , the results highlighted a noticeable retardation , specially for task involve enceinte information transfer .

Because BitLocker will be turn on by nonremittal , that could mean that tidy sum of mass will set up the update without realizing they ’re pick out a smash in SSD execution . Notably , Microsoft has only confirmedits plan to enable BitLocker by default option through support documents , which do not mention any potential performance drawbacks .

This could either mean that Microsoft has get hold a way to winnow out likely carrying into action emergence or does n’t deem this job to be big enough . As BitLocker becomes a nonremittal feature , users with SSDs , particularly those with elderly or slower models , should be aware of possible carrying out hits .

It ’s also worth note that BitLocker will only be on by nonpayment for new PCs , such as the presently availableCopilot+PCs , or if you execute aclean install of Windows . promote an existing Windows 11 system to 24H2 will not enable this feature mechanically . Similarly , if you are using a local account instead of logging in to a Microsoft story , reflexive encryption will not be enabled by default and can be manually activated via the BitLocker selection under configurations or Control Panel .

There are upsides to having it on by nonpayment , of course . By enabling encryption by default , you ’ll benefit from enhanced surety without needing to manually trip or configure the options . This initiative is expected to have a pregnant impact , specially for non - techy folk who might not otherwise enable such feature .

There are a dyad of other security changes rolling out with the upcoming Windows 11 update , too . first off , the update is expected to simplify encoding by remove the need for certain hardware lineament that were antecedently necessary . Notably , devices no longer involve Hardware Security Test Interface ( HSTI ) or Modern Standby to enable automatic encryption . The update also eliminates the need to check for untrusted Direct Memory Access ( DMA ) port , streamline compliance with Hardware Lab Kit ( HLK ) standards for manufacturing business .
