Quantum LPS-52AT

Quantum LPS-52AT

An odd size and memorable because of it. Quantum drives, in their brushed silver finish, always looked immaculate.

These were quite common at the time, one of the first really common Quantum drives, and we still saw them around once in a blue moon up until about 1998 or so. I wonder if the factory performance figures below are correct, as the LPS-52AT always seemed quite a bit slower than that in practice.
