Is hardware RAID worth it?

What is the difference between hardware raid and software raid?

Answer:

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.
