The Tsunami Ultimate II 3500 Dual Hard Drive enclosure packs great performance which is impressive for a USB enclosure. Moreover, it looks appealing and is a doddle to setup. For the tiny sum of £22 the Tsunmai Ultimate II, you really do get a lot for your money with this product.
My only quibbles about this enclosure is that it’s simply USB compatible. As a product which offers to enclose two hard drives and therefore offer a large storage capacity, it would seem reasonable to offer a faster connectivity option such as eSATA.
With that in mind the Tsunami Ultimate II 3500 JBOD scores 4/5.
