Iomega HDD 20 GB in the test: External hard drive for USB 2.0

Test system

For the test For the external USB 2.0 hard drive, we opted for a very fast Intel Pentium 4 system with 2.53 GHz. The Asus P4T533-C with Intel i850E chipset and ICH2 Southbridge, which we have already tested, served as the mainboard. Fortunately, the board already has OnBoard USB 2.0, which is implemented by an additional controller from NEC. In the new Intel Southbridge, the ICH4, on the other hand, no additional controller is required, since USB 2.0 has now been integrated into the chip. For comparison, we used a total of three IBM hard drives, which should represent three hard drive generations. The oldest of the group is the IBM DJNA-370910 with a capacity of 9.1 GB, which was one of the top models a good three years ago. The direct successor of the DJNA, the DTLA-307030 with 30 GB capacity, as well as its further development, the IC35L040 with space for 40 GB of data, which appeared one year later, were included in the test for reference purposes. We also tested Iomega's USB 2.0 hard drive in two operating modes (with and without activated Windows write cache). To avoid any questions, the following is the complete system listing.

Benchmarks

To determine the We have based our hard drive performance on a total of three different programs that provide the main theoretical performance data for the mass storage devices. HDTach was used to determine the read and write performance on the unpartitioned drive. The tecBench Disk Benchmark was used to measure the access times, which play a role that should not be neglected during normal work, since the first 500 MB of the test objects are also accessed here. In order to move away from the theoretical measurement results, the Business Winbench 99 1.2 was also used.

  • HDTach 2.91
  • tecBench Disk Benchmark
  • Business Winbench 99 1.2
