Why raid 0

The second thing is capacity. So the use of disks with different capacities is uneconomical because of the inability to use their full storage potential. This is what happens when you comment at 2am after a 20 hour coding bender. Very informative and I would love to check out more!

Some systems might stripe 1KB of data from disk 1 to 10 and then start all over again while others could stripe data through the odd numbers first and the even numbers next.

It depends on whether the striping happens at the byte, block, or partition levels. The downside of RAID 0 is that it has no parity and hence no-fault tolerance. This makes RAID 0 completely unsuitable for critical data. Also called mirroring, this RAID level replicates data across two or more disks for better redundancy.

This configuration requires a minimum of two drives, so data can be written to both simultaneously. This makes read operations fast as the data can be read from both the drives at the same time. However, write operations will be slower since the data has to be written to two disks. You have a situation where you want the read and write to be super quick, but the data is not so critical. The best example of this scenario is caching live stream video. Your investment in data safety increases your drive costs since each RAID 1 volume requires two drives.

Your data is spread across all the drives in the RAID along with information that will allow your data to be recovered in case of a single drive failure. At least three drives are required for RAID 5. No matter how many drives are used, an amount equal to one of them will be used for the recovery data and cannot be used for user data. You can lose any one disk and not lose your data. Just replace the disk with a new one. Your investment in data safety increases your drive costs since at least three drives are needed.

Hardware vs Software RAID RAID can be implemented in hardware, in the form of special disk controllers that are typically built into a multi-drive enclosure, or in software, with an operating system module that takes care of the housekeeping required for data to be written properly to the disks used in the RAID configuration.
