Which method of fault tolerance is least expensive per MB of storage disk duplexing or disk striping with parity?

has to be raid 5. raid5 with the parity will consume about 1/3 of the disk space but will give just about the highest level of fault tolerance.
raid0 - disk striping - will give you the full disk space but no fault tolerance
raid1 - disk splitting/ duplexing - will give you full redundancy but will cost 50% of your disk space
raid5 - parity - will do block-level striping with parity data , disk space cost about 30%, redundant

Advantages and disadvantages of Storage area network?
One disadvantage of using a Storage Area Network is that it would be very difficult to keep up your data if it breaks down. The disadvantage is price, with regards to stability, funtionality and speed, it's second to none.
Distinguish between primary storage and secondary storage?
Primary storage, also known as main memory or internal memory, refers to the storage space in a computer that is directly accessible to the processor. Primary storage is typically used to store data and instructions that are currently being used or processed by the computer. Secondary storage, also known as external memory, refers to storage space that is not directly accessible to the processor, but is used to store data and instructions for longer periods of time. Secondary storage is typically used to store data that is not currently being used, but that needs to be kept for future reference. There are several key differences between primary storage and secondary storage: Speed: Primary storage is generally faster than secondary storage, as it is directly accessible to the processor. This means that the processor can access and retrieve data from primary storage more quickly than it can from secondary storage. Capacity: Primary storage is typically smaller in capacity than secondary storage. This is because primary storage is used to store data that is currently being used or processed, while secondary storage is used to store data that is not currently being used. Cost: Primary storage is typically more expensive than secondary storage, as it requires faster and more expensive memory chips. Volatility: Primary storage is generally volatile, meaning that it is lost when the power is turned off. In contrast, secondary storage is non-volatile, meaning that it retains data even when the power is turned off. Location: Primary storage is located inside the computer, while secondary storage is typically external to the computer and is connected to the computer through a port or interface.
Why does raid o not provide fault tolerance?
Different RAID systems have different effects on multiple hard drives. RAID 0 combines storage together. Say you have 2 250GB HDDs combined with RAID 0: that you gives you, essentially, 500GB of storage. The problem with RAID 0 is that if one of the drives were to fail, then the other is to fail too, because of the way RAID 0 works by distributing strands of data over both disks. RAID 0 is sometimes not considered to be a true RAID system because of the lack of fault tolerance. RAID 1 and 5 are more complex to describe, but they generally deal with the same thing: backups. Instead of combining storage, RAID 1 and 5 deal with clones of a particular drive to offer redundancy if one were to fail. Say you have 2 250GB HDDs under RAID 1, essentially giving you 250GB of storage. If one drive were to fail, then the other would serve as a replacement if such were to occur.

Which method of fault tolerance is the least expensive per MB of storage disk duplexing or disk striping with parity?
Disk duplexing requires writing the same data twice and requires an extra controller.Disk striping with parity only writes once and requires only one controller. Although the parity information in disk striping with parity does take up some space, it does not take up as much space as the duplicate data in disk duplexing.therefore,disk duplexing is more expensive.
How many RAIDS are available for fault tolerance methods?
RAID (Redundant Array of Inexpensive Drives) is the technology developed to decrease risk involved with the usage of individual disks for Storage. RAID adds realibility & provides performance in Read methods. Well Known RAID Levels are 1. RAID0 - Striping, 2. RAID1-Mirroring, 3. RAID2 - Striping at Bit levelusing Errorcorrection code on disks, 4. RAID3 - BYTE Level striping with parity disk, 5. RAID4 -Block Level striping with Dedicatedparity disk, 6. RAID5 - Striping at Block level with Distributed Parity, 7. RAID6 - Block level striping with Dual Distributed Parity.All RAID levelsenable Fault Tolerant storage volumes except RAID0.
What RAID implementation provides no fault tolerance?
RAID level 0RAID 0RAID 0 (block-level striping without parity or mirroring) has no (or zero) redundancy. It provides improved performance and additional storage but no fault tolerance. Any drive failure destroys the array, and the likelihood of failure increases with more drives in the array.

Where can someone find information on great storage places for expensive family jewelry?
One can find information on great storage places for expensive family jewellery from: Great Space Storage, Manhattan Mini Storage, House Beautiful, Better Homes & Gardens, Storage etc, Extra Space, Loop Net, Find Storage, Bank Rate, to name a few.
What can be used to provide fault-tolerance to a system?
RAID storage can be used to provide fault-tolerance to a system. With RAID, data is stored redundantly on a set of disks to mitigate against failure of a disk.
What type of RAID volume is used for fault tolerance and only requires two drives?
RAID 1 is mirroring without parity or striping. It requires a minimum number of two drives and has a fault tolerance of one. RAID 1 works by writing data to both drives, thereby producing a mirrored set. When the read is requested, it is serviced by the drive that has the lowest seek time plus rotational latency. An example of this set-up is two 1TB drives in RAID 1 that have a combined total of 2TB of storage, but because they are in RAID 1, the effective storage space is 1TB as data is mirrored on both drives. It is effectively a real-time back-up system. If one drive fails, data is not lost.
Where can you find the least expensive but large storage building?
In order to find a reasonably priced large storage building you should consider a metal storage building or barn. These types of structures are way less expensive than regular wood framed structures and they come in kits andhave ÊDIY insturctions.
