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, it need delete all volumes in disk.

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:

Windows NT 4.0
Windows 2000
Windows XP Professional
Windows Server 2003

Doesn’t support

Windows 9X/Me, DOS
Windows XP Home Edition

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.
