Recovering Data from RAID

In today's world, everyone has long understood the value of information and the enormous potential inherent in the development of IT technology. Since servers and computers can fail, the question of how to ensure data security arose automatically, since the loss of important information can bankrupt entire companies, and losses can reach many millions. This in turn led to the emergence of RAID arrays, a technology that is designed to prevent data loss by combining several drives into one array. However, as the practice has shown, RAID arrays can also fail.

In this article we will look at the main causes of RAID failure.

Data integrity and security is a very important issue for anyone who uses a computer. Mac users are no exception. In this article we will explain how to create a software RAID in Mac OS, why you should do it and what RAID type is the best to use.

Multi-drive arrays in RAID5 configuration provide an excellent balance of performance, security, and price, so they are often the user's choice. What are the features of this RAID level? What problems are specific to RAID5? How to deal with unexpected situations? How to recover data from RAID 5 or the entire array if it is damaged?

Each year, the performance of computer hardware is increasing at a high rate. Processors are equipped with a large number of cores and streams, and graphics cards with a higher chip frequency. However, as for hard drives, it seems that their limit has been reached a long time ago and has been frozen since then. HDD specifications have recently been changing only in capacity, but not speed. SSD drives can correct this situation, but as a rule, they are much more expensive and have relatively low resource potential. Even before the advent of SSDs, so-called RAID arrays were invented in 1987. Below we will tell you what these arrays are, what kinds of arrays exist, and why a typical user needs them.
