Lab tested disk storage products using both large and small files

Lab tested disk storage products using both large and small files

The GCN Lab needed a common platform for comparing removable-media storage devices. Although throughput would have been faster on a desktop system, I chose a notebook computer because one of the Imation SuperDisk drives tested had to connect through a PC Card.

The platform was a 266-MHz Pentium MMX notebook running Microsoft Windows 95.

The lab staff measured throughput of each device reading and writing data. I used 100K, 500K and 1M files to average the small-file transfer rate in kilobytes per second. The large-file tests used 2M and 4M sizes. I also tested the notebook's standard floppy drive with the 100K and 500K files for comparison.

The Imation Corp. drives were tested both with and without their acceleration software installed. The numbers in the table are without the acceleration software. Although the software sometimes enhanced performance significantly, it did so in an unpredictable manner. I was more interested in the baseline performance.

The overall grades took into account throughput performance, ease of installation, included software and overall usefulness.
