Choosing the appropriate RAID configuration for your computer at work or at home is a relatively straightforward task. In practical terms there are only three commonly used configurations RAID 0, RAID 1 and RAID 5. In order to choose which of these is most appropriate for you you need only ask yourself what it is you require from the RAID. Do you want faster access times, do you want increased protection for the data against hardware failure or are you looking for a balance of the two?RAID 0 offers no additional protection for your data but will optimise the access speed. RAID 1 will work rather more slowly but will write each file twice (usually once to each of the two discrete hard drives which make up most RAID 1 configurations).RAID 5 (probably the most commonly used) offers a combination of increased access speed when compared to storing the data on a single hard drive and data protection requirements (any one of the hard drives within a RAID 5 array may fail without losing any user data).Which ever is selected should you be extremely unlucky and still lose access to your critical data then you need the services of an expert in raid such as Tierra Data Recovery Scotland.
