Using RAID-5 for data storage offers a primary benefit of providing redundant storage along with parity information. This configuration allows data to be distributed across multiple disks, which not only enhances read speeds but also adds a layer of fault tolerance. In the event that one disk fails, the data can still be recovered using the parity information stored on the remaining disks.

Parity data in RAID-5 is calculated through an algorithm that combines data from the available disks, allowing for data recovery without the loss of information. This means that while there is a trade-off in terms of write performance due to the overhead of calculating and writing parity information, the overall benefit of improved reliability and protection against data loss is significant.

In contrast, increased speed without redundancy disregards the safety aspect and may lead to data loss. Lower cost compared to single-disk storage isn’t inherently a characteristic of RAID-5, as it generally requires a minimum of three disks and one disk’s worth of space for parity. Additionally, space requirements do not necessarily decrease with RAID-5, as the need for multiple disks means physical space considerations depend on the number of drives used. Thus, the core strength of RAID-5 lies in its ability to deliver both redundancy and data integrity through the use
