There are many factors involved in the speed at which your drive is initialized. Here are some recommendations that can help improve the functionality of the SSD in this type of situation:
- Make sure you have the most recent firmware for you Intel SSD:
- Verify that you are using the most recent drivers for your motherboard and storage controller.
- Update the BIOS of your motherboard.
- Check for Windows updates, since diskpart and dynamic disks are a feature of Microsoft Windows*.
Keep in mind that when you do a Secure Erase, a value of "0" is written to all the cells of the SSD, and all data on the drive is wiped out. The behavior of Diskpart and dynamic disk creation may be different for "new" and previously initialized drives.
Dynamic disks are different than basic disks, since they can be used by Windows to do Software RAID, and other configurations. Creation of dynamic disks may take longer than creating a basic disk, depending on the configuration you plan to use.
Diskpart and Dynamic Disks are Microsoft Windows* features, so the best source for details about this tool and the way it works is Microsoft Support.
Please review the following document from Microsoft for additional details about dynamic disks:
