It was glimpsed at CES 2020, Samsung’s new M.2 980 PRO SSD is now officially announced. It stands out for its NVMe PCIe 4.0 interface and above all for its record speeds. Samsung announces up to 7000MB / s read and 5000MB / s write. In comparison, the 970 PRO model currently sold achieves 3500MB / s read and 2700MB / s write.
To achieve these record speeds, Samsung is relying on the fourth generation of the PCI Express interface, which allows speeds to be doubled overall. On the other hand, the SSD will only be able to run at full speed on motherboards that support PCIe 4.0, for example those with the AMD X570 chipset. The SSD can also work with PCIe 3.0 motherboards, but at reduced speed.
On the components side, Samsung uses a house controller, called Elpis, up to 1 GB of SDRam cache memory and TLC flash memory (three data bits per cell). The controller has a nickel coating to dissipate heat, combined with a dissipation plate located on the other side of the SSD.
The SSD 980 PRO is available in three capacities: 250 GB, 500 GB and 1 TB. However, Samsung does not specify when it will be on sale, or what its price will be.
