Answer and Explanation:
If we consider RAID 5 which contains the property of hot-swappable, which means regardless of whether your drives come up short (and in the end they all does) you can change the drive on the server without closing it down, so on account of RAID 5 no personal time will be there.
Mirroring is likewise completing in RAID 5, so there is no doubt of information getting lost. In spite of the fact that while the way toward changing the drive (hot-swap) is going on, the customers framework may be dynamic by then of time perhaps a few, so the customer may see a slack while this procedure of investigating is going on.
