DELL XPS 13 WITH TOSHIBA 1TB XG3 PERFORMANCE
Our initial testing of the Toshiba XG3 1TB NVMe SSD can be found here and resulted in transfer speeds of 2.6GB/s read and 1.6GB/s write, making it the fastest 1TB NVMe M.2 SSD in production. Unfortunately, it is a client SSD and not available for purchase. We believe that we may see a 1TB M.2 of similar performance released shortly but cannot confirm or elaborate.
For our results, we followed our SSD Optimization Guide and we also checked off the write-cache buffer flushing option, as well as turning off Enhanced Intel SpeedStep Technology (EIST) and C States in our BIOS/UEFI. We have never had problems with these optimizations on any of our machines but. once again, we reflect on our procedures for your information, not recommendations. So….let’s see the performance…
Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.
There have been many questions as to whether the NVMe SSDs have been working in 2 or 4 lane because of the low write performance. As we can see here, our SSD is operating in X4 and is listing 100% health.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
Our initial ATTO performance displays write performance 5x better than the stock Dell XPS 13 which is incredible. This is the best performance we have ever seen from a ultrabook, although it still doesn’t reach the full potential of this SSD.
Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
