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.

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.
Which is more stable raid implemented by windows or raid implemented by hardware?
Raid implemented by Hardware is more stable than RAID implemented by Windows
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.
How do you hook up two disc drives in a raid format?
You hardware has to support RAID technology, read the manual for your motherboard. If you have Linux you can have software RAID which is slower than hardware but still can be used to for mirroring, striping and so on. In the manual should described how to create RIAD (0, 1 and so on). You can have RAID software for windows too, but it's expensive and perfomance is not that great.
What additional hardware will be necessary to implement two identical hard drive?
Hardware will be RAID PCIe / PCIx RAID hardware controller but The hardware RAID is often the motherboard RAID controller or a separate RAID card.
What hardware is needed to implement hardware RAID for fault tolerance?
raid card
What is raid 7 Difference between raid 6 and raid 7?
RAID 7 is triple parity RAID 6 is double parity.
Which version of raid is supported by windows xp does this raid version provide fault tolerance?
Windows XP supports spanned and striped RAID 0 volumes Hardware RAID is considered a better solution for fault tolerance than software RAID RAID 0 does not provide fault tolerance
What form of software can also called firmware?
That'd be software installed directly onto a piece of hardware which is the operating code for that piece of hardware. For example, a hardware RAID controller might have firmware on it that controls its operation.
How can different disks be configured for a RAID in Windows?
The answer depends on whether one is looking to configure RAID via hardware or software. Windows is capable under disk management to run RAID via software. The first step is to convert to a dynamic disk. Then the RAID levels supported, in parentheses are Striped, 2 disks (0) Mirrored, 2 disks (1) Striped with parity, which required 3 disks (5) being the three most popular. That said if RAID is being done at the hardware level, then the operating system is oblivious to the fact that it is being raided at all and simply reads what the RAID controller tells it to. In this scenario all RAID levels are suported. For a deeper discussion on raid levels the following site is excellent. http://www.acnc.com/04_01_00.html
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.
