Other programs for measuring transfer rates and access times of optical drives have failed so far as well because they cannot cope with the REV's capacity. Since the CD/DVD benchmarks use "real" data, as opposed to low-level benchmarks, our results are not the final word: a different data set could produce different results.
Data Transfer Rate
We obtained the following results using the copying program xxcopy 2.85.5a. It generates a post-procedure report for determining the real transfer rates.
The maximum value of 24.5 MBps stated by Iomega is absolutely realistic in this regard and in view of the rotation speed of 4,200 rpm. We can say the same for the minimum transfer rate under ideal conditions: Here, Iomega promises approximately 12.7 MBps. The REV is absolutely suitable for real-time saving of big data streams (e.g., video).
| Data | Measured Transfer Rates |
|---|---|
| Small files (5286 files, 760 MB) | 5.2 MB/s |
| Large files (15 files, 5.2 GB) | 21.4 MB/s |
| Large & small files (49,887 files, 27.9 GB) | 11.9 MB/s |
