![]() The SpecWorkstation 3.1 Storage subsystem score really shows the performance delta between the Optane SSD DC P5800X and even flagship consumer NAND flash drives like the Sabrent Rocket 4 Plus. The updates in version 3.1 offer significant improvements in how workloads partition and distribute threads across multi-core CPUs, expand support for next-generation GPUs, and add features such as vectorization that leverage advanced CPU hardware to accelerate performance. The SPECworkstation 3.1 benchmark includes more than 30 workloads containing nearly 140 tests that exercise CPU, graphics, I/O, and memory bandwidth. This drive is currently the best value flash drive on the market by a long way.Initialized as GPT and formatted as NTFS in windows, we get a useable space of 745GB.ĬrystalDiskInfo shows us connected at the maximum PCIe 4.0 x4 bus speed while utilizing NVMe 1.3. We will update the price if/when the drive becomes officially available in the UK but until then we have calculated its value rating based on the price we paid (£18 including shipping) from Hong Kong. Our test unit had to be shipped from Hong Kong where we were able to purchase it at at an extremely reasonable price. The SanDisk Extreme has not been released in the UK. The other benchmark observations were all consistent and to date this drive has the highest sequential read we have seen on a 16GB flash drive. ![]() We suspect the inconsistency relates to the way the controller batches page cleanup. The SanDisk Extreme achieved a 4K random write speed of 2.1 MB/s which was over three times faster than the best of the rest, unfortunately we were unable to get consistent measurements but 2.1 MB/s was towards the lower end of the range (7.46 MB/s - 1.71 MB/s) we observed. Until now every flash drive we have tested has shown a serious weakness in the area of 4K random writes. The benchmark scores for the SanDisk Extreme were stunning.
