Hard Drive and Raid Data Recovery


The fastest fault tolerant array configuration but the least storage efficient array, it's probably the most commonly used system today. As other array configurations require three or more drives, it is the only choice in a two-drive system. The two drives in the 'mirrored pair' appear to the operating system as one; they always mirror each other. Should a drive fail the data is available from the other. If you cannot access data from either of the mirrored arrays, you must be having a bad day because this is the most reliable storage array.

As the data is always the same on the two drives, read performance is almost doubled, as consecutive reads can occur on each drive at the same time. Write performance is not improved.

If you have any problem with RAID 1, find out which array is problematic and try to access the data from the other array. If you cannot access data from either of the arrays then at that stage you need professional help for data recovery. Further tries to recover data yourself may lead to more damage to problematic hard drives in the array. This will increase data recovery cost and in some cases, it even makes data recovery impossible. If you had any questions, feel fry to call us for further assistance.
