Two new samsungs vs three wd blues for read only in raid 0

Which would be faster for read only... (sample streaming)

Two 32mb cache Samsung hd103uj 1tb sata drives in raid 0.

Three 8mb cache 320gb WD Blue's in Raid 0.

I know that three is better than one but the new samsung is so fast in read....

Anybody positive enough about this to give me good advice about which to do?

Am using for music keyboard sample.. loading for piano samples and want maximum polyphony.

I could go ahead and buy another blue... and go four...

? This is my first thread at good old Toms Hardware Guide... so help a bro out.
