Teac HD 15OT & HD-15 PUK A

4. WinBench 99

Ziff Davis Media's WinBench 99 is a subsystem-level benchmark that measures the performance of a PC's graphics, disk, and video subsystems in a Windows environment. WinBench 99's tests can run on Windows 95, Windows 98, Windows NT, Windows 2000, and Windows Me systems.

HD-15 PUK A...

TEAC HD 15OT...

According to WinMark 99, compared to the HD 15OT, the HD-15 PUK A reported higher scores in the Business and High-End test suites. Its access times were marginally lower (i.e. better), while CPU Utilization (measure of the percentage of total processor time the PC spends running the test) was much higher (i.e. worse). Transfer rates pretty much confirm what we saw with HD Tach.

Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. Iometer is pronounced “eye-OM-i-ter,” to rhyme with “thermometer.” Iometer does for a computer’s I/O subsystem what a dynamometer does for an engine: it measures performance under a controlled load. Iometer was formerly known as “Galileo.”

Iometer is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). It can be configured to emulate the disk or network I/O load of any program or benchmark, or can be used to generate entirely synthetic I/O loads. It can generate and measure loads on single or multiple (networked) systems.

Iometer can be used for measurement and characterization of:
• Performance of disk and network controllers.
• Bandwidth and latency capabilities of buses.
• Network throughput to attached drives.
• Shared bus performance.
• System-level hard drive performance.
• System-level network performance.

For the specific test, we ran a simulation of a File Server workload. The HD-15 PUK A reported better overall performance and only in the case of CPU Utilization was it worse, although the difference was negligible.
