Marvell launched Bravera as world’s first PCIe 5.0 SSD with maximum speed of 14 GB/s

Chip manufacturer Marvell (Meiman Electronic Technology) officially launched the world’s first PCIe 5.0 SSD master chip Bravera SC5 series on May 28. The bandwidth of the PCIe 5.0 channel is twice that of 4.0, so this master will achieve a transmission speed of up to 14 GB/s and random performance of up to 2 million IOPS.

Officials said that the SC5 series master control can meet the needs of cloud data centers and achieve ultra-low latency operation for real-time applications. The SC5 series main control supports the NVMe 1.4b protocol. In order to meet the requirements of enterprises, it has FIPS security certification, AES 256-bit encryption and other functions.

This master controller is equipped with the hardware-level “Elastic SLA Enforcer” function for the first time, which can greatly reduce CPU usage and improve user experience.

As can be seen from the figure, the prototype product equipped with this master control adopts a new E1.S specification interface and the circuit board to meet the requirements of power supply and chip quantity. The main controller supports 16 NAND channels for the first time to improve performance.

When developing this product, Marvell worked with cloud service providers such as Microsoft Azure to ensure that the product complies with the standard. In addition, the SC5 series main control is the world’s first product that supports SEF, ZNS, Open Channel, and other use environments without hardware changes.

Marvell master uses the 5th generation NAND Edge LDPC error correction technology and supports 3D QLC, TLC, SLC, and other NAND flash memory. The master control helps to extend the life of flash memory particles and has energy-saving features.

Foreign media said that Microsoft Azure, AMD, Intel, Hynix, and other companies congratulated the launch of this master chip. Marvell stated that the company has established a good cooperative relationship with KIOXIA, which will be used in cloud storage and data center products in the future.

In addition, Renesas Electronics announced that the company’s power management chip will help meet the demand for PCIe 5.0 solid-state drives equipped with SC5 master control.
