As I understand it, if you are using Raid-5 will break at least one disc, you'll have to restore all the data.
Is it really so?

How to recover data from Raid 5?

I recommend during Assembly of the array to provide one spare (spare) disk and enable automatic rebuild of the array — in the case of a single disk failure the array will be in degraded mode, but will immediately start rebuild on a spare disk. Also, if the controller allows, you can include the so-called disk scraping in periods of low activity, the RAID will read the entire contents of each disk for errors — this reduces the probability that the departure of one disk and rebuild the array (this will read all the disks) will color another disk because of the increased load. This feature is not on all hardware controllers.

No, the data will be intact. Will only need to rebuild the array after replacing the failed disk with a new one, to make data consistent.

I can only add that the process of adjustment may be long. I have failures sevens (the problem intelliskin wood for 64bit) 2 TB, built for 19 hours. Although at this time you can continue to work. Just do not forget that the loss of two of the three disks — the data is not restored, so that failure of one quickly find a replacement.
