RAID – what a matrix for the home user?, Part2
RAID 1 – high security 
To use RAID 1 we need a minimum of two drives. During the description matrix that often goes back to the phrase, because all RAID 1 writes data on two disks, which can be stated that the drive is a mirror reflection of another. This solution makes data security is at a very high level. In the event of failure of one of them, absolutely not lose any information.
This is why RAID 1 is recommended for people with a matrix that, above all, put the safety of information stored on your computer. If they are extremely valuable files, you can consider an investment in RAID 1. And what will be considered, as RAID 1 to the financial interest is not – available to the user capacity of the matrix is really bad, it might take up to 50 percent. complete subsystem. Yes, yes, our results are only half the total capacity, so – for example – the combination of the two drives totaling 640 GB of capacity, we can only use 320 GB of space.
While RAID 0 mode might be interested, the RAID 1 is not – by far – for the home user. The average holder of a computer does not store the relevant data so that the investment in this matrix. For completeness it is sufficient to perform regular backup (backup), which may be out on an external hard drive or even a portable USB flash drive – depending on how much data you need to copy. It is also a secure solution, and has certainly a lot cheaper. Let look Houston laptop repair company.
And finally, an information: RAID 1 provides high security data, but performance is not as great as in RAID 0. Compared to a single drive, only the reading of data is clearly better. For this reason, the typical user does not pay attention to the matrix described.
Matrix RAID – looking for this!
Best RAID for home users, from which you can use now if we have two hard drives. Matrix RAID combines the advantages of RAID 0, RAID 1!
If you choose Matrix RAID, you can make a drive to work in RAID 0, RAID and the other in 1. In this way, we receive a very fast disk subsystem (with RAID 0), as well as provide the high level of security of data (the advantages of RAID 1).
In this case, it is recommended that the drive working in RAID 1 to store the most valuable files and documents, and use RAID 0 drive system, which will serve us for the processing of large portions of data.
Any disadvantages? The total capacity of disk space available to us to be less than it would if we took the same RAID 0, part of the data (this with RAID 0) is also vulnerable to failures. In this case, it is a more cost-effective, because the Matrix RAID will provide us with both speed and safety, and appropriate use – storage of individual files on selected drives – we can reduce the risk of losing valuable data to a minimum.
One must also note that Matrix RAID is a relatively new technology, so we find it in the newer motherboards with due south bridge (for example, Intel motherboard with P45 chipset and ICH10R bridge – the letter “R” means the RAID). RAID 5 – for demanding, check also Detroit laptop repair.
The next and last disk, which I decided to describe in this article, you RAID 5. It is interesting to know about this version, although it does not apply generally in the typical computer user.
RAID 5 requires at least three drives. Capacity has not increased in terms of recording data, but it is higher in case of read (similar to RAID 0). This is possible because none of the drives is not only to store control codes – all of the drives contain both code and data. For this reason, the reading may be higher, because the data are collected simultaneously with multiple units.
In the event of failure we can recover the data: information on RAID 5 are written on all disks, but when one is damaged, lost files can be recovered. After the use of RAID 5 capacity is made available to us for a drive less than would apply in reality, but thereby gain confidence that the data is safe. When one of the drives is corrupt, the effect of RAID 5 will slow to replace the drive until a new one.
Matrices for the masses
The prevalence and relatively low prices of motherboards that support RAID hard drives and make you start to consider using one of the matrix. Combinations of certain types of calls to us because it opens the way for the benefits of hard disk drive, which a single drive is not in a position to offer.
Just select the RAID? This article is postarala briefly describe the most important / most disk, but the choice – for the home user – is probably obvious. The most worth Matrix RAID, which can be longer if we have two hard drives. This mode combines the advantages of RAID 1 and RAID 0, so that we can divide the capacity of eg two disks, so that after 40 percent. their capacity was a RAID 0 and przyspieszało the system, and the remaining 60 percent. was configured as RAID 1, and care about the safety of important data.
