Once configured and setup, one thing we did notice was that the device is not NCQ compatible. This results in some abnormally low random access high QD results. In order to provide an accurate representation of the performance of the device we compiled results from two setups with the device itself.
The first result will be performance with the HDD alone in the device. The second set of results will be with the SSD installed alongside the HDD in the device.
Lastly, we will test the results with the SSD alone, outside of the device. The main point of that will be to explore if we are losing any functionality of the SSD by using it in the device.
After the synthetic benchmarks are complete, we have compiled a few real world tests to show if these results equate to real world usage.
ATTO Disk Benchmark is the quickest and simplest method to determine transfer speeds and utilizes the same test methodology as manufacturers in arriving at performance results. It simply measures raw sequential transfer speeds for both read and write access at various transfer sizes, producing a very easily understood result. This benchmark is by far the industry standard for spot-on raw sequential throughput.
As we can see, the maximum read of the HDD alone is roughly 100 MB/s.
After installation of the SSD into the device with the HDD, the performance jumps immediately. Now the device is reading off of the SSD itself, and the performance shoots up to 225 MB/s!
Finally, we test the SSD alone, connected directly to the computer. It reads at 284 MB/s, so you can see a bit of speed is lost to the data duplication running in the background when installed together in the system.
