We spotted Phison PS5016-E16-based SSDs from over half of a dozen of companies at Computex several weeks ago and we are sure there are many more to come. While almost all suppliers demonstrated peak sequential read/write performance numbers of their upcoming drives, nobody showcased random read/write performance numbers. Last week Japan-based CFD company introduced its PS5016-E16-based drives and finally revealed all the information about their speed.
Because all Phison PS5016-E16-powered SSDs feature a PCIe 4.0 x4 interface, it is natural that they offer sequential read/write speeds of up to 5.0/4.4 GB/s which significantly exceed performance of contemporary high-end drives featuring a PCIe 3.0 x4 interface. Meanwhile, in real life random read/write performance affects user experience far more substantially than peak sequential read/write speeds and yet these numbers in case of PS5016-E16-based drives have never been disclosed until recently.
Fortunately, CFD published all the details about its PG3VNF SSDs, including random read and write performance numbers. As it appears, 1 TB and 2 TB versions of the drives offer up to 600K IOPS random read as well as up to 500K IOPS random write speeds. When compared to Phison PS5012-E12-based Corsair’s MP510, the new drives are not necessarily faster.
