storage options for MacBook Air


I've decided to setup my MacBook Air for digital audio, all of my music is currently saved on a WD external hard drive. My question is, would it be better to keep it on the external hard drive or move the music over to the MacBooks' 256 GB solid state drive? are there other storage options I should investigate? thank you!

The original question was to store music on an external drive or on internal drive. For 1, in time your ssd will be too small to hold all of your music. The 2nd issue is that hard disks are noisy to have in your audio room.
options? Plenty.
1) use a cloud drive (NAS drive essentially). This drive can be in another part of the house. I use the seagate central 5TB disk. used to use this for my Audirvana library from my Mac mini.
2) share a disk from another server. This is what I use now. Explained later.
3) hook up an external disk to your router.
4) I have a 2TB battery operated disk that holds part of my library. I mainly use this when I travel since my iPhone/iPad can connect to this drive wireless and the my iPhone/iPad connect to a cypher lab dac which sounds fantastic.

i stopped using iTunes for my music room years ago because no matter what software you used on the Mac to read the music. It didn't sound that good. When Audirvana 2 came out with its own library instead of using iTunes, music sounded much better. About 8 months ago, I started auditioning music servers and most that I heard bettered the Mac mini setup. 

So I replaced my Mac mini setup with the Auralic Aries. I since setup my Mac mini as an OS X server running minimserver. I have 15TB of hard disk on the Mac mini server using a raid 1 setup for 2 - 5TB drives for my music. I use Bliss that keeps the tagging and album art insync. This server is in the basement 2 floors away from my music room. I use the seagate storage central cloud disk to backup the OSX server.

bottomline, you have many options

Thank you for all the comments!
Looks like there's a lot of options and the Auralic units seems popular, this is something I'll have to look into a little later. I need to decide how much of a commitment I want to make to digital to shell out for a music server. I have so many sources to play with and have fun with all of them.
I'll setup what I have and add BitPerfect to see how it all sounds.
I have been doing the computer audio for about a year 256 gb. Is pretty small maybe 2000 cds not to mention high Rez. Files. It is my thoughts that the less the computer has to do the better the sound. So keep your music separate. 
I have set it up with the music on an external HD and really pleased with what I'm hearing at this point, thank you!
Hi scar - 
Glad things are sounding good.  If you haven't yet, get the BitPerfect.  It's only $10 bucks and easy to install and set up.  Might improve the SQ even further for you.  The BitPerfect people also provide great tech support.
