Webb6 aug. 2024 · RAID 4 has such similar to RAID 0 features as fast reading operations and large storage capacity, at the same time, this level incorporates its own feature of extended internal error correction. If some stripe becomes unreadable, the controller is capable of reconstructing it based on the information from other stripes and parity.

Webb16 feb. 2012 · RAID-1: This type is also known as disk mirroring and consists of at least two drives that duplicate the storage of data. There is no striping. Read performance is improved since either disk can be read at the same time, meaning if one disk is busy the other is accessed. Write performance is the same as for single disk storage. WebbRAID-3 provides a similar level of reliability to RAID-4 and RAID-5, but offers much greater I/O bandwidth on small requests. In addition, there is no performance impact when writing. Unfortunately, it is not possible to have multiple operations being performed on the array at the same time, due to the fact that all drives are involved in every operation.
