engadget - Ah, the sweet aroma of competition in the air. That's what we've gotten a whiff of after catching an (admittedly grainy) shot of what appears to be an internal Blu-ray writing / HD DVD reading combo drive from Hitachi. The GGW-H20N should have no issues playing your favorite high-definition films on either format, and it can also burn 50GB dual-layer Blu-ray discs, BD-R, BD-RW, and the typical flavors of writable DVDs and CDs. Reportedly, the drive will also boast a speedy SATA interface and will posses a read rate of up to 6x and burn rate of 4x, but the most important detail was unsurprisingly omitted. Bring on the price drops.
