Iomega presents drive with capacity 1 Tb

Device with capacity eqaul to 1 Tb, named oficialy Iomega Desktop Hard Drive XL is one of rrecent most advanced drives ever seen. It should present 1 terabyte capacity (it is containing 4 harddrives with capacity 250 Gb) But its reliability is lowered (4 times bigger probability of mistake). Question is, if Iomega will sell that device without its drives, 250 gb is not top capacity this day. Lets hope similar devices can be bought withut drives.
