In fact, WD has been quite conservative in their claims, and has actually put in numbers that are more representative of sustained usage for the PRO-G40's use-case. Western Digital claims read and write speeds of 2700 MBps and 1900 MBps respectively, and these are backed up by the ATTO benchmarks provided below. Yet another use of these synthetic benchmarks is the ability to gather information regarding support for specific storage device features that affect performance. The results translate to the instantaneous performance numbers that consumers can expect for specific workloads, but do not account for changes in behavior when the unit is subject to long-term conditioning and/or thermal throttling. Synthetic Benchmarks - ATTO and CrystalDiskMarkīenchmarks such as ATTO and CrystalDiskMark help provide a quick look at the performance of the direct-attached storage device.
