SSDs tailored to the PCI-Express 4.0 interface and able to take advantage of the dual bandwidth it provides over the PCI-Express 3.0 interface are becoming more widespread - and this trend may explode later in 2020 with a possible gradual transition to officially support the new generation of its products as well Intel plus those from .

After some early efforts based on controllers From companies that specialize and focus on the field (Phison first and foremost), it seems that our time has come to see the products of larger makers who are independently developing controllers - and Samsung will be one of the first in this wave with the promising 980 Pro.

Samsung's leading home-market model was featured in its massive booth at the CES 2020 show, with no full technical details - but with a promise of impressive 6,500MB of continuous read speeds (close to a theoretical limit of about 7,000MBs per PCI-Express 4.0 interface) × 4) and 5,000 megabytes per second in writing. These drives will be officially launched later this year and will offer modest volumes of 500GB, 250GB or one terabyte - which may indicate that they are still based on chips In the long-time MLC technology for maximum longevity.

The 970 Pro drives knew how to deliver Random of just over 400,000 IOPS at their peak, while controllers 4.0 Leaders claim to offer up to 1,000,000IOPS. Where in this range will the 980 Pro models land?

We do not have any other technical details about the controller on which the 980 Pro drives will be based, which are no doubt intended to replace the old 970 Pro drives sold in stores (at consistently high prices despite the large competition) from early 2018 - but will be very interesting to examine Its capabilities in working with small, random files compared to the second generation of PCI-Express 4.0 drives on the market, which will be based on the The advanced E18 that is expected to be ready for action in the near future.
