Cloud is “hot”, everyone is talking about it, everyone uses it, everyone keeps data in the “Cloud”. However, do we know what it really means? Let’s look at a cloud without a marketing shell – at the myths and facts. Confusion in the Clouds Where does the Cloud begin, and where does it end? You may say: “Yes, I have access to my data from various locations. I can choose the capacity of services. I [...]

Modern technology – we all know its rules, laws (like Moore’s law), limitations, possibilities and direction of development (well, for the most part). Technology is still evolving… But what if we change the starting point? What if we bet on a revolution, not evolution? What if we stop thinking of computers as silicon-based systems? Let’s discuss the issue of biocomputers and DNA computing. The evolution of a revolution Have you ever heard of artificial DNA? [...]

After RAID 0 and RAID 1 (with RAID 1+0 and RAID 0+1) it is time for RAID 2, 3 and 4. Here we present a small description of the mentioned levels. We hope it will outline a picture of the functionality of these solutions. Although the article is a kind of history lesson – these solutions are no longer used – it is good to be aware of the origins of modern storage technologies. RAID [...]

This is the second article from our RAID series. We hope it shows – in the easiest possible way – what RAID is, the idea of it and how it works.  We wrote about RAID 0. Now is the time for RAID 1, RAID 0+1 and RAID 1+0. What is RAID 1 RAID 1 (mirroring) – the basic idea of such a solution is the replication (mirroring) of two or more discs. It means that [...]

We published an article about RAID 5: “How does RAID 5 work? The Shortest and Easiest explanation ever” – now is the time for the whole series.  We will try to show you, in a few words, the shortest explanation for RAID standard levels – 0, 1, 1+0, 0+1, 2, 3, 4, 6 and Matrix.  Now is the time for RAID 0 – take a look… What is RAID 0 We can describe RAID 0 [...]

A journey of a thousand miles begins with a single step – always. The same applies to technological progress – It begins with the simplest solutions, if you look at it in terms of time. Take a look at the inventions which have become the starting point for present giant data centers. They were only the drop in the bucket, but remember, progress is a continuous process. It has continued, it is still ongoing and [...]

Mass data storage – you think it is boring. Am I right? If you believe so, let me change your point of view. We would like to present a list of ten ideas – or rather prophecies. Some of them have been fulfilled, some not, yet one question will remains unchanged: what will be next? Furthermore, where are the limits of technology evolution – or maybe revolution? Is it simply a limit of human imagination? [...]

We all have limited time to study long and complicated information about RAID theories, but you may be interested as to how RAID 5 works. We made it simple for you by providing the shortest and easiest explanation ever. RAID 5 – how it works? First we need to remind you XOR definition: XOR function result is equal 1 if both arguments are different. XOR (0, 1) = 1 XOR (1, 0) = 1 XOR [...]
