I have just seen the new 6 Gig SATA drive arrays from Maxx Digital. They are 16 bay drive arrays, with FOURTY EIGHT TERABYTES of storage, and can do 1600 MB/sec (this is no typo). HOLY CREATIVE COW, this is going to change everything. There are two different host adaptors that will be able to do this. Units are in beta and will be released BEFORE NAB 2011.
