Quantum Fireball CR 8.4B HDD Review
Quantum Fireball CR 8.4B HDD Review - PCSTATS
As it stands right now, not even the fastest ATA/66 drives are able to exploit the ATA/66 interface to its fullest extent.

Benchmarks: WinMark99

The following tests were run 3 times each for the Business Disk Winmark and the High-end Business Disk Winmark. The average of the 3 test runs are given here. All numbers under Ziff Davis' Winbench are given in KB/sec. Adaptec's Threadmark 2.0 (run 3 times as well) figures are given in MB/sec. CPU utilization numbers are as shown.

The average CPU utilization of this drive under NT is 4.34%
The average CPU utilization of this drive under 98 is 8.81%
(Computed under Threadmark 2.0)

CPU utilization is a bit higher on this drive than on the Quantum Fireball CX 13.0GB but still within reasonable limits. As you can see, the Business Disk Winmark score are significantly lower than the High-end scores due to the fact that the business applications tested do not rely on intensive disk reads with large files.

The ATA/66 interface has faced severe criticism being accused of delivering mediocre improvements (if any) over the previous ATA/33 interface. But before words start to fly, let us look at the numbers. Take this Quantum drive for example. The maximum burst transfer rate from the disk to the buffer is 194 Megabits/sec or 24.25MB/sec.

This rate is nearing the limits of the capability of the ATA/33 interface. With internal transfer speeds doubling every three years, the 24.25MB/sec would translate into 48.5MB/sec making the ATA/33 the apparent bottleneck in hard disk performance. ATA/66 was created to give current technology the time and space it needs to grow. So although we may not immediately see the benefits of ATA/66, you certainly will see it in the near future once internal data transfer rates of hard disks start to grow. So be wise and neglect those negative comments towards the ATA/66 movement and remember, it is not the interface which is not showing the results, but rather the current state of hard disks.

The overall performance of the Quantum Fireball CR 8.4GB is on par if not better than other hard disks of Quantum's competitors operating at the 5400 rpm level. Though this model was released in early 1999, it still qualifies as solid performer right now in early 2000 with a good number of 7200 rpm out on the market such as Quantum's own Fireball KA and KX models.
