Redundant Array of Inexpensive Disks or RAID is a set of techniques in stringing 2 or more hard disks together to enhance overall drive performance and/or ensure data survivability in the event of hard disk catastrophe.

The term “Redundancy” can generate mixed feelings among computer users. On one hand, it conjures an impression of wastage, yet in mission critical applications, it is a necessity and a savior in times of crisis. RAID is a specialized solution to a specific problem. It does not address system stability problems associated with operating system vulnerabilities, viruses, human error and software issues. RAID Redundancy was designed to improve data survivability and system uptime in the event of hard disk catastrophes. Is RAID Redundancy for you? Is your data worth more than the cost of another hard disk?

 

If there is one thing that can break EVERYTHING in your computer, it is the power supply unit.

Computers can usually last for a long time if proper care is taken and it starts at the Power Supply Unit (PSU). The power supply or common wall-adapters are the most under-appreciated component – not very interesting and usually out of sight. Unlike the central processing unit (CPU), Graphic Processing Unit (GPU), memory or hard disks, upgrading it does not improve the overall performance of your computer. If so, why do we need to worry about it?

Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T. or SMART) is a hard disk technology that keeps track of the operational state of the drives in your computer.

Hard disk failure is one of the most common computer hardware problems other than motherboards and power supply. For many who have experienced the excruciating pain of losing months or years worth of data, having an early warning system would have been a god-sent. Here are a few important things to know about Hard Disk S.M.A.R.T. technology.

The modern disk drives are generally fairly reliable. However, unbeknownst to many people, the chance of failure can often be higher in the first few months of operation.
