freefilesync mirror vs update vs two way

With 2-way synchronous mirroring, usable capacity is 25% – ¼ of storage space 3-way synchronous mirroring At the same time, RAID5 and RAID6 configurations can be used for SSD setups due to a high tolerance to physical failures and faster performance of the latter. RAID6 in a HDD setup gives low write performance. In case of RAID5 use in a HDD setup, there arises the risk of disk failure while rebuilding RAID5. * RAID10 use is recommended for a HDD setup. Taking into account that each storage node has only 50% of usable capacity with RAID10, synchronous mirroring makes the further dividing of those 50% by half resulting in the underutilization of storage capacity – only 25% is used. 2-node HA ensures the synchronous mirroring of data between two storage nodes. This configuration requires storage redundancy on the nodes. Cost-efficiency 2-way synchronous mirroring This document suggests taking a look at two-way and three-way synchronous mirroring to better understand the benefits each of them has behind. At the same time, the data is considered written only when the primary storage receives a signal that all secondary copies have been created. One of the techniques includes synchronous mirroring – an approach when a source storage has an exact replica (one or more).

Modern technologies offer a variety of methods how to warrant a highly-available and fault-tolerant storage. The value of business data grows to the extent that companies simply cannot ignore the importance of a safe data storage.
