It’s not too hard to find Blu-ray recorders that feature integrated hard drives, but Panasonic’s DMR-BR30 that was announced for the Japanese market features a slot for swappable hard drives. The idea of this recorder is probably to mimic the functionality of VHS cassettes. The bad news is that you won’t be able to take just any hard drive, but you’ll need to buy Panasonic’s DY-HDD500 500GB hard drive for $240 a pop. It connects via a USB connection and is only supported in this recorder. With it, users will be able to copy videos from Blu-ray discs or DVDs to the hard drive or vice versa.
