However, RAID 5 will not offer you the same speed as RAID 1 or the same capacity as RAID 0. So if one drive fails, you can easily replace it with a new one, and the array will automatically recreate your RAID configuration. Just like with Disk Mirroring, the drives in this array are also hot-swappable. These bits of data can also serve as redundancies. A parity bit is an additional binary digit that helps your array check if there’s any error or missing segments. But, aside from striping the data, it also stores parity bits on the drives. Now, when you write data in this array, just like in RAID 0, your data is broken down into units and spread over the hard drives in your array. If you have at least three hard drives, using RAID 5 will break your data into segments and save those segments across your drives. RAID 0 is best used for storing temporary files or files that you have backed up elsewhere.Īlso known as “disk striping with parity,” RAID 5 is about speed and redundancy. Plus, since you are using multiple disks, the chance that one of them will fail is increased. And, since your data is stored and processed across multiple drives, losing the data on one drive means you lose all of the data on all of your drives. That means if one of your drives fails, you lose all the data on that drive.

However, RAID 0 does not include any redundancy (or backups).

Using RAID 0 is faster than getting a large hard drive with the same capacity because you would only have one hard drive processing data instead of multiple drives in an array. This is called striping, and it helps you access data faster because you have multiple drives working together to read, write, and store data. Then it spreads that data across all of the drives in your array. When you save a file, RAID 0 breaks the data into segments called striped units. However, if one drive fails, you will lose all of your data. This will help with read and write speeds. If you have at least two drives, using RAID 0 will combine them and write data on both of them simultaneously or sequentially, depending on your system. Also called “disk striping,” RAID 0 is all about optimizing the speed of your hard drives.
