Samsung's new PCIe 4.0 SSDs: 8GB/sec and they can 'NEVER DIE'

While the drive technically can die, Samsung has mad it much less likely than it is for other SSDs.

What just happened? Samsung, already one of the market leaders when it comes to solid-state drives, could cement its position at the top with the release of two new SSD lines.

The South Korean tech giant said its 30.72TB PCI Express (PCIe) Generation 4 Non-Volatile Memory Express (NVMe) SSD series has fail-in-place (FIP) technology that allows it to continue operating even if its NAND chips stop functioning.

Samsung is now calling the two SSDs PM1733 and PM1735.

The PM1733 will be offered as six models in a 2.5-inch U.2 form factor offering storage of between 960GB and 15.63TB, as well as four HHHL card-type drives offering between 1.92TB and 30.72TB of storage.

Samsung Electronics released bar-raising solid state driver (SSD) solutions for big servers and data centers with unmatched memory and guaranteed permanent storage. Samsung says its FIP software can detect a faulty chip, scan for any damage in data, then relocate the data into working chips, thus avoiding the costs associated with system downtime and hardware replacement.

Samsung launches fail-proof PCIe Gen4 SSD

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.

In general, NAND chip defects usually require the whole systems to be turned off when swapping the malfunctioning SSD or performing data backups.

Meanwhile, the SSD virtualization technology allows the PM1733 and PM1735 to subdivide a single SSD into 64 smaller SSDs.

In addition, the newest SSDs will have V-NAND machine learning technology.

For instance, the 12.8TB PCIe Gen4 NVMe SSD (PM1735) has 14 times the sequential performance of a regular SATA-based SSD, with up to 8 GB per second for reading and 3.8 GB per second for writing operations. Furthermore, the PM1733 offers single and dual-port options to support server and storage applications, as well as multi-stream writes and SR-IOV.

Cloud storage providers can also utilize the SSD virtualization feature to extend their services to a greater number of clients using the same amount of resources. This provides server administrators to create multiple independent, virtual workspaces for several users. This can be done to promote optimized product competitiveness. Both features help ensure that the PM1733 and PM1735 maintain their superior data reliability despite high SSD speeds.
