Disk Redundancy Research
1) RAID stands for redundant array of independent disks, originally redundant array of inexpensive disks.
2) It is a good idea to use RAID to enhance performance and storage.
3) A) RAID 0 - block-level striping without parity or mirroring
B) RAID 1 - mirroring without parity or striping
C) RAID 5 - block-level striping with distributed parity
D) RAID 6 - block-level striping with double distributed parity
4) It is better for increased performance.
5) RAID 1 can be relatively high due to redundant drives. It is very reliable because it uses two drives for backup.
6) I would choose RAID 6, because it is more reliable.
7) Unlike software RAID, Hardware RAID requires specialized hardware to handle the drives.

7) The x64-based versions of Windows 7 do not permit the installation of unsigned drivers under any circumstances. TRUE
8) You cannot convert an MBR disk to a GPT disk without erasing all data on the disk. TRUE
9) You cannot extend a striped volume unless it is on a dynamic disk. FALSE
10) Windows 7 can access VHD’s without the use of a hypervisor. TRUE
