Samsung unveils new PCIe 4.0 SSDs that "never die"

Samsung unveils new PCIe 4.0 SSDs that

Samsung's PM1733 and PM1735 series come in 19 different models covering the HHHL (card-type) and 2.5-inch U.2 formats.

Samsung hopes to usher in a new paradigm in SSD performance with the release of the PM1733 and PM1735.

For now, the SSDs featuring FIP will be for use in data centers where anything that helps ensure data integrity and minimizes the need to switch out storage is going to be welcomed with open arms.

"We are combining breakthrough speeds and capacities with revolutionary software solutions as we accelerate expansion in the premium SSD market", said Kye Hyun Kyung, Samsung's Executive VP of Memory Solution Product and Development.

Nearly a year after outlining their first roadmap for PCIe 4.0 SSDs, Samsung's first two models are in mass production: the PM1733 and PM1735 high-end datacenter SSDs.

KitGuru says: These new SSDs from Samsung could be the most interesting drives we've seen in a long time.

The PM1733 and PM1735 series' PCIe 4.0 standard is built upon the fourth generation Peripheral Component Interconnect Express motherboard interface. It reads sequentially at 8.0GB/s and randomly at 1500K IOPS while offering capacities up to 30.72TB for U.2 (Gen 4 x4) configurations and 15.36TB for the HHHL (Gen 4 x8) form factor.

Samsung began mass production of the two new chips last month. This means normal operations can continue even when errors occur at chip-level, enabling what Samsung calls a "never-dying SSD". ' When a fault is detected in a single chip, the data is scanned for damage and relocated to non-faulty components - effectively a sort of Redundant Array of Independent Chips. Better still, it allows for some virtualisation tasks - including Single-Root I/O Virtualisation (SR-IOV) - to be offloaded onto the drive itself, reducing CPU overhead. With this, cloud operators will be able to offer more users services with the same SSD resources and also reduce the virtualization workload of server CPUs. This can be done to promote optimized product competitiveness.

Finally, Samsung's V-NAND machine learning software is created to predict and verify cell characteristics and variation in circuit patterns. It also detects variation among circuit patterns using big data analytics. Not only are the speeds super high, but this new "fail in place" technology could also be a huge improvement for SSD reliability and data recovery.
