		SPECs
		-----    
		Crucial M500    500/130 MB/s [R/W]  [SATA3/SSD]       3/1/0.5 W
		WD RE3          113 MB/s sustained  [SATA2/7200/16MB]  8/8/1   W
		WD Red          145 MB/s sustained  [SATA3/~/64MB]     5/~/0.6 W 

		CONCLUSIONS
		-----------
		- SATA II [3 Gbps; 2.4 Gbps; 300 MB/s effective] is sufficient for all HDD 
		- 4x WD Red HDD @ SATA 2 [each @ 145 MB/s] => USB 3 :: Ext RAID 0 using 2 disks ~ 600 MB/s
		- Read @ SSD is SATA2-limited; Write is SSD-[self]-limited
		- R/W @ 3xWD-RE3 is HDD-[self]-limited, but near SATA2 limit
		- R/W @ 2xWDGrn is HDD-[self]-limited, well below SATA2 limit

		4 x SATA2/HDD @ RAID0 ~= USB3 ~=   1 x SATA3/SSD
