Samsung is currently in the final stages of readying a new M.2 NVMe Gen 4 solid-state drive—the SSD 990. This product is set to bridge a gap in Samsung's client SSD lineup, specifically targeting the mainstream market with a strong emphasis on 'cost-effectiveness'. It's worth mentioning that the SSD 990 marks a departure from its predecessor, the 990 EVO Plus. The latter was a high-performance offering in the PCIe Gen 4 era that notably lacked a cache.
