We call this container a partition. You can have one partition that contains all the storage space on the drive or divide the space into twenty different partitions. You must first create at least one container with a file system.

Partitions are necessary because you can’t just start writing files to a blank drive. On many storage devices, a single partition will often take up the entire drive.

For Veracryt, Boot is UEFI with SecureBoot disabled.Īlso, I used the following procedure to obtain the results: 1) configure BIOS of laptop for UEFI and Secure Boot, fresh install windows 10Pro, update it, reboot and run CD to get the 'no encryption' results 2) turn on bitlocker, wait until bitlocker completes system encryption, reboot, run CD to get bitlocker results 3) turn off bitlocker, reboot, go in laptop BIOS and turn of secure boot, once booted, install VeraCrypt v1.22-Beta3, system encrypt with veracrypt using defaults, once veracrypt encryption completes, reboot, run CD to get veracrypt results.The partition can contain all of the storage space on the drive or just some of it. If it matters, booting is UEFI with Secure Boot enabled for results with no encryption and for encryption with Bitlocker. Here are my before and after CrystalDisk (CD) Mark results on the same laptop (HDD, not SDD) with a fresh install and updated version of Windows 10Pro v1703. I'm seeing the same issue as Savin in my testing to compare Bitlocker vs. I have added the volumes to system favorites.Īny idea what is the cause of this problem and how to fix it? System level encryption PIM is not stored and is not used for the other volumes, which are mounted successfully after system boot as the boot password is the same for all volumes. I'm testing the second SSD, which is also encrypted at partition level and will post results later.īoth partition level encryptions are with default PIMs. Slow speeds are confirmed also on normal copy operations, it's not some testing program problem. The original drive letter is unassociated with the hard drive and the same letter is mounted by VC. The problematic HDD is encrypted on partition level. Here is the problematic disk before VC encryption: Here is the system SSD performance, full disk encryption with PIM: Only the system SSD performance is ok after encryption. I have tree drives on my system, two SSD drives and one HDD. I'm having strange problem with two of my drives.
