This is software RAID. All you need to do is connect the drives and configure the RAID level you want. Software RAID does its processing on the server motherboard. This adds to the processing load and could slow down the RAID calculations and other operations carried out on that device. RAID 0 and RAID 1 place the lowest overhead on software RAID, but adding the parity calculations present in other RAID levels is likely to create a bigger impact on performance. Numerous server OSes support RAID configuration, including those from Apple, Microsoft, various Linux flavors as well as OpenBSD, FreeBSD, NetBSD and Solaris Unix. Herein lies another difference: with software RAID you'll be restricted to the RAID levels your OS can support. Software RAID is often specific to the OS being used, so it can't generally be used for partitions that are shared between operating systems. Hardware RAID With hardware RAID, because the processing work is done on a discrete controller card in the server or at the level of the storage subsystem, there's no added load to the server processor and buses. There will likely be more advanced features, such as drives being hot-swappable in case of failure. Hardware RAID is more expensive than software RAID, but offers better performance and interoperability. Whether software RAID vs hardware RAID is the one for you depends on what you need to do and how much you want to pay. Hardware RAID will cost more, but it will also be free of software RAID's performance limitations. Powerful Modern CPU The performance of a software-based array is dependent on the server CPU performance and load. With today’s faster CPUs, software RAID outperforms hardware RAID. Can RAID Array Fail? Yes. The entire RAID array can fail taking down all your data (yes hardware RAID card do dies). Use tapes and other servers that can hold copies of the data, but don’t allow much interaction with it. Move your data offsite. Another option is to use two or three RAID cards. Combine them together to protect your data. This make sure you gets back your data when one of your RAID card dies out. Hardware vs Software Recovery My personal experience – recovering from software RAID is easy. However, sometime finding out exact hardware RAID requirements can be a nightmare. A good backup can save from RAID hardware incompatibility problems. Software RAID allows you to mix different drive and sizes. You can not do something like this with hardware RAID cards. With software RAID you can swap the drives to a different server and read the data. There is no vendor lock in with software RAID solution. You Can Not Go Wrong With Hardware RAID There is an old saying in IT – no one ever got fired for picking RAID controllers. Use Both Hardware and Software RAID Sometime you need to use both hardware and software RAID to get the best of both worlds. For e.g. set up 4 mirror pairs, 2 on each hardware RAID controller, and use software RAID0 to put it all together. This will give the best performance for database server. Here is another example from one of our DR site server (this box mirrors our 30+ production server files and database):

1. BHai ... Windows me RAID 1 ka status kaise pata karte hai hai... ki ye sahi kaam kar raha hai ki nhi.... koi harddisk fail to nhi kar gayi hai... any CMD to check jaise linux me bahut sare cmd hote hai
2. bahi jaan aap sirf hardware he btain gay ,,ya kbe sofware example c++..data base
3. Brother once raid0 been created & u start saving data in the drive. will there be security issue ?
4. Nice video very use ful.
   Sir mera laprop asus model k84hr.
   mene bois level pay RAID create try kiya but nehi hotahe.
   humhra jo sata mode only two options (IDE/AHCI) RAID nehi mila.
   please help.
