In general (there are lots of different devices so specifics may differ) all the disks in a Raid 5 are seen as a single logical disk.  Some versions let you configure the set of disks as multiple logical disks.

For Read-Mostly applications like the squeezebox/slimserver, the performance is generally N times better than a single disk where N +1 is the total number of disks you have (3 times faster for your 4 total drives mentioned).  Write performance varies based on the exact pattern of accesses.

It is much more reliable than a single disk, but for most purposes you should still have backups.  (music is generally not critical, but it is expensive/time consuming to replace)

Hello, i've heard of Raid 5, if someone is using it i would like to have
an opinion. Are the disks seen as one disk? It would be easier  to
browse with the Squeezebox. Is it faster and reliable?
I would like to buy a Pci SATA card and 4 300 G° Hdds in the future.

Thanks in advance.
