Dynamic disk introduction - Management of Dynamic disk

We may manage disk through Disk Management of Computer Management. Disk Management supports not only basic disk, but also dynamic disk. We may use upgrading guide to transform basic disk to dynamic disk. And we can simultaneously use basic disk, dynamic disk and different file systems (FAT16, FAT32, NTFS on the same computer system. To transform dynamic disk to basic disk, all volumes in disk must be deleted and all data will be lost by doing so. However, you may copy the volume to backup data in advance.

Microsoft Windows doesn't support dynamic disk on notebook computer, removable storage, USB or disk with FireWire interface. Basic disk and dynamic disk can not be mixed in the same disk.

For dynamic disk, Windows supports following operating system:

SCSI Short for small computer system interface, a parallel interface standard used by Apple Macintosh computers, PCs, and many UNIX systems for attaching peripheral devices to computers. Nearly all Apple Macintosh computers, excluding only the earliest Macs and the recent iMac, come with a SCSI port for attaching devices such as disk drives and printers. SCSI interfaces provide for faster data transmission rates (up to 80 megabytes per second) than standard serial and parallel ports. In addition, you can attach many devices to a single SCSI port, so that SCSI is really an I/O bus rather than simply an interface.

Hardware realization

RAID card It can realize RAID function. It has a RAID control chip and manages data alone. It is fast and has certain fault-tolerance.

Hard disk In order to make the best of RAID, the speed request for hard disk is generally high. We may choose interfaces like SCSI, SATA and so on to guarantee the visit speed.
Solution scenario based on hardware is better than that on software in technical and service performance. Specifically, in abilities to detect and recover multi-bit errors, RAID protected bootable array, error disk automatic detect, leaving space replace, array reconstruction, common or appointed leaving space and colorful code alarm etc. the former is better than the latter. Moreover, it has abilities to erect multi-RAID, remotely detect and manage for multi-operating system. RAID based on hardware has high security and low CPU occupancy rate.
