Quick question for storage in nMP (for musician)

Hello all,

It's been the longest wait ever but the Mac Pro will be finally here tomorrow.

I am just wondering what the best solution would be for me regarding storage. I need more space than what the Mac Pro can offer so I am thinking about doing this:

- Drobo 5D
- 5 SSD 1TB each

Is this the best I can get? Clearly as you might have noticed it's not really a matter of $.

Please let me know if there's any other solution. I need 3-4 TB and fast streaming (I am a musician).

P.s. Is reading time on SSDs faster than 7200 rpm right? Sorry for my ignorance:o
