Almost any volume can be mirrored, including
the system and boot volumes
Read Speed is Fast & Write Speed is Slow
Fault Tolerance is available

What Is a Mounted Drive?
Is assigned a path rather than a drive letter
Allows you to add more drives without using up
drive letters
Adds volumes to systems without adding
separate drive letters for each new volume

Differences Between the FAT, FAT32, and NTFS
Key differences:
Partition size limits
Sector size limits
Security
Data compression
3
Types of Disks
Basic Disk
Dynamic Disk
You can create volumes that can span multiple disks
There is no requirement for contiguous space when
increasing or extending the size of a volume
4
Types of Disks
Benefits of Basic Disk
Setup and Recovery Console access
Benefits of Dynamic Disk
Spanning multiple disks
Fault-tolerant capability
5
What Is a Partition?
A physical disk is sectioned
into separate partitions
A physical disk can have up to:
Four primary partitions, or
Three primary partitions
and one extended partition
Extended partitions are
subdivided into logical drives

Types of Volumes
Simple Volume
Spanned Volume
Striped Volume (RAID-0)
Mirrored Volume (RAID-1)
RAID-5 Volume (Striped With Parity)

What Is Fault Tolerance?
The ability to survive hardware failure
Fault-tolerant volumes provide data redundancy
Fault-tolerant volumes require dynamic disks
Fault-tolerant volumes are not a replacement for
backup
8
What Is a Simple Volume?
Contains space on a single disk
Can be created only on dynamic disks
Can be extended if formatted with NTFS
Fault Tolerance is not available
Spanning is not available
Read & Write Speed is Normal

What Is a Spanned Volume?
Spanning is available
Minimum - 2 Hard Disks
Maximum - 32 Hard Disks
Includes disk space from two or
more disks, filling the first disk,
then the second, and so on
Fault Tolerance is not available
