"One of the biggest features of AMD’s expensive X570 motherboards is PCI-Express 4.0, especially when it comes to storage. Typically the fastest PCI-Express 3.0 NVMe drives averaged around 3500 MB/s, but with PCI-Express 4.0 you are going to get around 5000 MB/s or 5GB/s! That is a massive increase in speed and in a world where time is money and no one wants to wait for that transfer or game to load the extra cost for that speed is worth it. Today we are going to be taking a look at one of the first PCI-Express 4.0 NVMe drives and it comes from AORUS. The drive makes use of the Phison PS5016-E16 PCI-Express 4.0 x4 controller, Toshiba BiCS4 96-layer 3D TLC NAND, and a DDR4 cache chip from SK Hynix."
