In the second half of the year, several manufacturers, including Asus, Corsair and Crucial, plan to release new SSDs that use the high-speed PCI Express 5.0 interface. Most likely, these will be introduced in connection with AMD launching the Ryzen 7000 series processors, where precisely support for PCI Express 5.0-based SSDs via the M.2 interface is one of the big news.
Now it looks like Korean electronics giant Samsung is also joining the fall launch party. It’s the constant Twitter leaker Komachi (via Videocardz) who unearthed information from a database of the interest organization PCI-SIG, where a recent device has been registered. It is about the Samsung 990 Pro, which then becomes a direct successor to the current 980 Pro fixed with upgraded communication over four lanes PCI Express 5.0.
Specifications regarding the capacities or performance are currently unknown, but with the step up to PCI Express 5.0 there are theoretical possibilities to achieve transfer speeds of up to 16 GB/s over four lanes. Now, however, it must be said that the practical speeds are usually lower than that because of overhead in the communication bus, but it is not impossible that we may see sequential reads in the 13 to 14 GB/s range.
Notably, Samsung is likely to be one of the few manufacturers that will initially provide a device with a proprietary storage controller. Most of the other manufacturers that have announced units are apparently based on a reference platform from the circuit manufacturer Phison. However, exactly what difference can be expected in actual performance remains to be seen in the autumn when the devices are launched.
