When this drive originally came out I think Quantum and Maxtor were still two separate companies. So while this a rather dated drive these days, it works well representing the lower end of the consumers buying spectrum - after all, many purchases are driven by price first when all you really need is 20GB of space.
The Quantum Fireball Plus AS is a two platter 7200RPM 40GB hard drive with Ultra ATA/100 support and 40GB of storage. The Fireball plus comes with 2MB of cache buffer and demonstrates a average seek time of 8.4ms, and 0.8ms for track-to-track seek. It produces 3.4 bels of noise on average.
