Large storage arrays are much needed in today's world of computing largely due to the ever increasing need to save up every bits and pieces of information downloaded from the internet. In the past, the growth of storage was largely dominated by the capacity of a single hard drive. However, capacity growth has been slow and the growth of internet data has far exceeded storage capacities. With multimedia being the main key driver for internet traffic growth, personal storage capacities will have to grow with it.
This is where large storage arrays come into the picture. Storage arrays are not new and its concept is based on the combination of two or more hard drives to create a large storage volume, often for the purpose of performance and capacity. However, if your data's sole survival have to depend on two or more hard drives, the chances of a catastrophe is much higher.
This led to the introduction of four drive arrays based on a simple RAID 5 setup. In the past, such RAID arrays were only available to data servers and usually far from the reach of home users. The reason was because of the high requirements of processing needed to read/write data from/to the array. Thankfully, today's chip manufacturing technology has advanced so far that it's now an inexpensive hardware for most consumers. In fact, RAID 5 can even be emulated on your PC via software, although performance can be greatly affected if it's placed under heavy usage.
Today, we'll look at one such device that gives you the ability to configure high-end RAID 5 and 6 arrays for use in a home or small office environment. It's a self contained system, so you'll need only worry about installing the hard drives while software and configuration are all included for your convenience. Before we look at the product which we're reviewing here, let's find out more about RAID 5 and 6.
