Is Toshiba now competitive with Samsung and WD?

Real world benchmarks

To get a good idea of the performance of SSDs that you can expect in practice, we run several real world benchmarks, tests that are based on the disk usage of real applications.

First of all, the storage test of PCMark8. This benchmark uses so-called traces of Adobe Photoshop, Adobe Illustrator, Adobe Indesign, Adobe After Effects, Microsoft Word, Microsoft Excel, Microsoft PowerPoint, World of Warcraft and Battlefield 3. The individual scores of all tests can be found on the next page.

In the graphs below the first thing you see is the bandwidth score, which is the average read- and write speed, measured over all the different parts of the test. Traces are played back in real time, including idle time during the original recording of disk use. The total score is based on the geometric mean time it takes to run all tests, including the aforementioned idle time. This is why the results of all modern SSDs are very close to each other with the standard scores.

The Toshiba XG6 1TB achieves a storage bandwidth of 658.8MB/s, leaving behind all major competitors. Only the expensive Samsung 970 Pro and Intel's Optane SSDs score higher here. In terms of score, it did not reach 5100 points.

In addition to the PCMark8 real world tests, we also run three in-house developed real world benchmarks. These are traces based on a gaming workload (GTA V and Rise of the Tomb Raider), a light desktop workload (starting Windows, Microsoft Office and Google Chrome) and a heavy desktop workload (Adobe Photoshop and Adobe Lightroom). While PCMark8 disables all operating system-level caches during testing, we leave Windows read and write caches intact for our own real world benchmarks. As a result, these benchmarks may paint an even better picture of the performance of drives in practice.

The Toshiba XG6 performs a little less well in the tracing tests than in PCMark, although the speeds achieved are certainly not bad.
