Describe the differences between a hardware RAID and a software RAID?
Brief introduction about Hardware RAIDThe hardware-based system manages the RAID subsystem independently from the host and presents to the host only a single disk per RAID array.An example of a Hardware RAID device would be one that connects to a SCSI controller and presents the RAID arrays as a single SCSI drive. An external RAID system moves all RAID handling "intelligence" into a controller located in the external disk subsystem. The whole subsystem is connected to the host via a normal SCSI controller and appears to the host as a single disk.RAID controllers also come in the form of cards that act like a SCSI controller to the operating system but handle all of the actual drive communications themselves. In these cases, you plug the drives into the RAID controller just like you would a SCSI controller, but then you add them to the RAID controller's configuration, and the operating system never knows the difference.Brief introduction about Software RAIDSoftware RAID implements the various RAID levels in the kernel disk (block device) code. It offers the cheapest possible solution, as expensive disk controller cards or hot-swap chassis are not required. Software RAID also works with cheaper IDE disks as well as SCSI disks. With today's fast CPUs, Software RAID performance can excel against Hardware RAID.Difference between hardware raid and software raidObviously, hardware RAID is pricier compared to software RAID, due to the extra hardware that you need to purchase. The hardware is typically expensive, and adds a substantial amount to the cost of the whole system.On the flip side, the cheap software RAID can impair the host computer, which may result in poor performance. This is because it needs to process the data before it is written to disk, to determine where each piece of data should go.The controller in a hardware RAID handles these operations, so that the host processor does not have to. The host processor will simply write the data, just like in a normal hard drive.Tips: The performance hit taken by the system can vary a lot, depending on what type of RAID array you have in use. It could be very minimal, as with the case of a JBOD array. Or it can be quite substantial, especially with stripping and mirroring on multiple disks.Hardware RAID offers better reliability compared to software RAID. A software RAID can be prone to data corruption, due to the fault of the RAID software or driver that is being used. A software RAID can also be affected if the host computer is heavily loaded. Heavy processing can cause some pieces of data to be delayed by a small amount of time. These delays can add up, and negate the benefits of the RAID array to some degree.
Who led the raid the raid on tripoli?

How can you put air raid in English?
Air Raid.......
When did Chaseabout Raid happen?
Chaseabout Raid happened in 1565.
What does ARP stand for?
Air Raid Precautions
How do you configure the raid?
It depends on which RAID you mean: software or hardware. For hardware RAID read manual for your motherboard, for software RAID read software help.
What are differences between software raids and hardware raids?
Hardware raid is supported by hardware and usually more stable and achieve better performance. Software raid does not need raid hardware support and can be used on machines without raid options. In the same time stability and performance of software raid is not as high as hardware. Software raid is usually recommended for low budget machines (it's a part of many linux-based system, and it's free of charge) if you are not able to afford a good hardware raid.
What kind of software is available for RAID recovery?
There are multiple software’s available for recovering data from RAID but as RAID is a complex structure and recovering data from Corrupted RAID is a complex and time-consuming task so you should rely on a software tested and recommended by Data Recovery Specialists. One of such software is Stellar Data Recovery Technician that recovers lost or inaccessible data from RAID 0, RAID 5 and RAID 6 drives. This software is a complete solution with advanced features to recover files, photos, videos, emails etc. from Windows-based hard drives, external media and RAID array. You can try this tool for free and the tool can also be used in scenarios if probable RAID construction fails.
What is the difference between hardware raid and software raid?
Name says major difference between both. by the way Software RAID is created using feature provided by Operating System or any special software, but Hardware RAID is created using Hardware RAID controller Card. When you create RAID you are adding overheads to read and write operations. If you create software RAID and your server is too busy or you have many read and write operations you will see there is impact on performance. When you create HARDWARE RAID you will use dedicated controller with processor and some cache. This will not create overhead for your OS and you will find better performance. Software RAID will save some money for you but Hardware RAID will provide you value addition.
Which operating system has built-in software for RAID-5?
"The most common software implementation of RAID is the built-in RAID software that comes with Windows 2000, 2003, and 2008 Server." ~Mike Myers CompTIA A+ Guide to Managing and Troubleshooting PC's Third Edition~
What does the term raid server recovery mean?
The term "RAID server recovery" means just that: recovery of the RAID server. A RAID server is a computer that runs RAID software to act as a secondary storage.
Will there a season of Full Metal Panic based after the Second Raid?
There are side stories but another season based after the second raid will not be created.
Where can one buy Raid data recovery software?
RAID data recovery software can be bought and downloaded from many different online websites. The most reliable download can be found on the official RAID website but other websites such as Run-time are also reputable.
How can you recover your data after a raid?
There is software available, such as Runtime that can recover any information you have lost to a Raid. There are also companies such as RAID, and Data Tech Labs that can provide help in a situation where data has been lost to a raid.

You can install an OS on a spanned or stripe volume that uses software RAID?
no
Where can one shop for RAID array recovery software?
RAID array recovery software is best purchased directly from the companies that create each program, to avoid a bad download. Some places to try include Runtime Software and Disk Internals.
