In the case of hardware RAID, the type of controller you have matters, too. Servers and NASes in business datacenters. On a crash during a write, the Raid controller cannot guarantee the consistency of Raid stripes or atomic writes. Software RAID is a type of RAID implementation that utilizes operating system-based capabilities to construct and deliver RAID services. Part of that is software raid, but not what you are thinking. With software RAID your data can be split across different enclosures for complete redundancy - one enclosure can completely stop working and your data is still ok. While this causes a hardware RAID solution’s price to increase, it also means that that there is a dedicated RAID controller chip meaning it won’t be a burden on your computer’s CPU. - Talking about RAID is great,…but actually doing RAID is a whole different game.

There are also RAID levels combining two or more of the above RAID levels. Features of the LSI 2108/2208 Controller. 4 kernels, Linux's software-RAID (fakeraid) driver collection is called "ataraid", which has subdrivers for the various manufacturers' different software RAID schemes. RAID-5 is the most popular choice for storage arrays today, as it is relatively simple to implement at the hardware level and is able to continue to operate in the event of failure of a single device. 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. Configuration is still required, but that configuration takes place outside the system. The exception to the rule on software raid is XLV under XFS.
