The Durabook S15 delivers a robust performance across various benchmarks, indicative of its capabilities in handling a range of tasks from basic to moderately demanding applications.

In terms of storage performance, the Crystal Disk scores are quite impressive. The read speed of 3647.40MB/s and write speed of 2200.13MB/s suggest that the S15 is more than capable of handling large files and data-intensive operations swiftly, making it suitable for applications that require quick data access and processing.

The Geekbench scores offer a glimpse into the CPU's capability. A single-core score of 3970 and a multi-core score of 1871 demonstrate that while the S15 is competent in handling everyday tasks efficiently, it might face some limitations in heavily multi-threaded applications. The computed score of 8727 further underscores its adequacy for general computing tasks.

In the CineBench tests, which are more focused on the CPU's rendering capabilities, the S15 scores 4147 in multi-core and 1374 in single-core tests. These scores reflect its ability to manage moderately demanding rendering tasks, although it may not be the top choice for highly complex rendering work.

The graphics performance, as indicated by the Fire Strike and Time Spy benchmarks, shows a decent capability with overall scores of 2581 and 929, respectively. The laptop seems to handle standard graphical tasks well, but it might not be optimal for high-end gaming or advanced 3D rendering. The Wild Life score of 5757 further reinforces this perspective.

Lastly, the Windows Experience score of 8.1 is a good indicator of the laptop's overall capability to provide a smooth user experience for most typical applications and tasks.

The Durabook S15 appears to be a solid performer for everyday professional tasks, including data management and basic graphical applications. It offers quick storage speeds and decent CPU and GPU performance, making it a reliable choice for professionals who require a rugged laptop with balanced performance features. However, for highly demanding graphical or rendering tasks, it might be worth considering models with higher-spec CPUs and GPUs.

As well as the standard computing performance test, this is a tough laptop, and as such, the durability of the S15 also needed to be tested. In the product description, Durabook highlights that the laptop is IP5X rated and drop-proof to 4 feet. 

In the first test, the laptop was used in a CNC, laser and 3D print workshop, left between the Bambu Labs A1 and the SnapMaker Artisan with CNC tooling. It was left open to the debris created by the two machines. While most laptops will withstand this amount of dust, it can render keys and ports blocked. Here, due to the design of the keyboard, the dust was not an issue, and a quick shake and vacuum quickly returned the machine to an almost new condition. Likewise, the plastic port covers did their job of keeping dust out.

The next test was to see how the laptop would cope with being used in light rain. It's worth noting that this is not a waterproof laptop, so time in the rain was kept to five minutes. Here again, the laptop functioned without issue and continued to work after the product shot without issue. 

The final test was the drop test here, measuring four feet off the floor. The laptop was dropped, then dropped again, rotated, dropped, etc. and aside from a nasty crack as it hit the stone and then the wooden floor on countless occasions, it seemed to be absolutely fine.

  • Performance: 3.5/5

Should you buy the Durabook S15?

Deciding whether to purchase the Durabook S15 hinges on your specific needs. Its rugged design, MIL-STD-810H and IP5X certifications make it an ideal if you're a field professional working in uncontrolled environments, workshops, warehouses and factories. 

The inclusion of a 15.6” Full HD DynaVue display and options for Intel Iris Xe or NVIDIA Quadro T1000 graphics make it versatile for a range of professional tasks. Moreover, its lightweight and slim profile defies the typical rugged laptop stereotype, enhancing portability.
