Is RAID Make HD Died Sooner?

[texp4]

Will RAID make your hard drive died sooner than non-raid? Since they have to read/write twice everytime ?

Not that I've ever heard or experienced. There is obviously more heat generated by 2+ hard drives than just one, but this can be addressed.

I'm not sure what you mean. On RAID 1 you have to write twice every time, but still once to each HDD. To the best of my knoweledge, RAID does not decrease the life of your HDDs. However, the MTBF of a RAID 0 is half of the MTBF of an individual drive, because if one drive fails you lose the whole array. On the other hand, RAID levels other than 0 (ie ones that are actually redundant) have MTBFs greater than that of an individual drive.

As gnufsh stated, raid does not change the lifespan of any individual drive but the partition will be unrecoverably corrupted if a single drive fails in raid-0, so you can have a very high chance of data loss in this configuration, the more drives, the poorer the reliability. Other raid types can offer a lot of redundancy and still provide good performance, but it depends on the raid type and the number of drives in the array.
