About Basic Disk and Dynamic Disk

Many of us are cooperating with a computer hard drive every day, and it's necessary to know some hard drive basics in order to make full use of it. For example, what does convert to dynamic disk mean? 

There are two storage types of hard drives, namely basic disk and dynamic disk. As you know, dynamic disks come after basic disks, but now both are well supported by prevalent Windows operating systems, like Windows 10,8,7.  If you're interested in the main difference between the two items, here is a full explanation.

1. Number of volumes

  • Basic disk support only primary partitions, extended partitions, and logical drives. The number of primary partitions + extended partitions is not allowed to exceed 4.
  • When you change a basic disk to dynamic, you can create volumes that span multiple disks (spanned and striped volumes). Though the recommended number is 32 or less, you can still create up to 2000 volumes on a system. 

2. Flexibility for volume management

Dynamic disks are able to create fault-torrent volumes like mirrored and RAID-5 volumes, and most importantly, go compatible with all Windows OS from Windows 2000 to Windows 10.
