WD has just announced an online event on October 8, 2020 and this is expected to detail their next-generation products particularly for their gaming segment. The WD Black line was Western Digital’s high-performance segment but has been rebranded to serve a more catch-all segment particularly with gaming as suggested by the naming style WD_BLACK.
The event will be streamed one the WD_BLACK Twitch channel and is expected to include announcements for Gen4 devices. Closer look at the banner includes icons for desktop, laptop and consoles so this could be a series of products that are aimed at high-performance gaming storage for various platforms.
