Death Star
The Death Star is a type of fictional mobile space station and galactic superweapon featured in the "Star Wars" space opera franchise. The first Death Star is stated to be more than 100 km to 160 km in diameter, depending on source. It is crewed by an estimated 1.7 million military personnel and 400,000 droids. The second Death Star is significantly larger, between 160 km to 900 km in diameter depending on source, and technologically more powerful than its predecessor. Both versions of these moon-sized fortresses are designed for massive power-projection capabilities, capable of destroying multiple naval fleets or entire planets with one blast from their superlasers.
Deskstar
The IBM Deskstar 75GXP (six models ranging in capacity from 15 to 75 GB) became infamous circa 2001 for their reportedly high failure rates, which led to the drives being colloquially referred to as "Deathstar", due to which the drives were ranked 18th in PC World's "Worst Tech Products of All Time" feature in 2006. Note the simultaneously announced IBM Deskstar 40GV, a 5400 RPM version of the 7200 RPM 75GXP, did not suffer from the same reported high failure rate.
