This depends on the disk controller: &nbsp; Some controllers will not &quot;present&quot; the raid array to the server until the build is done, others will do it right away.<br />
<br />
The upshot of this is: &nbsp; As soon as the disk &quot;drive&quot; is viewable to the operating system, you can use it- even if a build is occurring.

It depends on the controller. &nbsp; I work with Compaq/HP Proliant servers and all the RAID cards they use continue to build while we install the OS, reboots and all. &nbsp;The disk access time is slowed down, due to the RAID set being built, but not enough to notice. <br />

Question, Is it a life emergency that you need to copy data while the rebuild is going on? Its never a good idea to do this at all. My suggestion is to wait and then properly copy the data over, Just my suggestion. <br />

Copy data to Raid 5 while being built?

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
