The 980 Pro follows the 970 Pro, it is again an M.2-2280 card with NVMe protocol. However, the built-in controller supports PCIe Gen4 x4 instead of PCIe Gen3 x4 – the theoretical speed of the interface thus allows almost 8 GB / s instead of 4 GB / s. The 980 Pro excites this with 6.5 GB / s reading and 5 GB / s do not write out. However, these values ​​are higher than those of previous NVMe PCIe Gen4 SSDs with Phisons E16 controller. They reach 5 GB / s and 4.5 GB / s.

Because Samsung will sell the 980 Pro with 250 GB, 500 GB and 1 TB, we assume memory cells with two bits (MLC) – with a possible 980 Evo, three bits (TLC) should be set. Durability and write performance are lower here, but the flash memory is cheaper to produce. However, there is a fast PCIe Gen3 SSD with the 970 Evo Plus, which is why Samsung could take its time. The 980 Pro is said to be loud PC Watch appear in Europe in February 2020.

The external SSD from Sandisk is also an NVMe SSD, but an external one with USB 3.2 Gen2x2 for theoretically 20 GBit / s. With the WD Black P50 Game Drive, there is already a USB 3.2 Gen2x2 SSD from the manufacturer on the market, but it only secures up to 2 TB. The prototype at CES 2020, on the other hand, has 8 TB. Sandisk did not say whether and when such an SSD will be available.
