CrystalDiskMark CrystalDiskMark provides various storage benchmarks, but we're interested in the returned 32-thread 4K performance numbers to see how well the drives fare when tasked with numerous small transfers.
AS SSD AS SSD measures performance against a trio of popular applications.
PCMark 8 PCMark 8's storage test is a collection of workloads that isolate the performance of the PC's storage system.
Iometer The hardest test we do, hitting the drive(s) with a mixed workload using differing number of users.


We are benchmarking a-new as we move SSDs on to the latest platform. This is why you will see only a trio of drives in the graphs. The purpose is to show you the benefits, if any, of moving from a good SATA-based SSD (Crucial MX300), to a first-gen PCIe NVME (WD Black), through to today's drive, the WD Black NVMe. Of course, price-per-GB goes up as we move to the fastest drives, but the following graphs ought to illuminate whether it is realy worth spending more cash.
