Marvell Announces First PCIe 5.0 NVMe SSD Controllers: Up To 14 GB/s []

Today Marvell is announcing the first NVMe SSD controllers to support PCIe 5.0, and a new branding strategy for Marvell's storage controllers. The new SSD controllers are the first under the umbrella of Marvell's Bravera brand, which will also encompass HDD controllers and other storage accelerator products. The Bravera SC5 family of PCIe 5.0 SSD controllers will consist of two controller models: the 8-channel MV-SS1331 and the 16-channel MV-SS1333.

These new SSD controllers roughly double the performance available from PCIe 4.0 SSDs, meaning sequential read throughput hits 14 GB/s and random read performance of around 2M IOPS. To reach this level of performance while staying within the power and thermal limits of common enterprise SSD form factors, Marvell has had to improve power efficiency by 40% over their previous generation SSD controllers. That goes beyond the improvement that can be gained simply from smaller fab process nodes, so Marvell has had to significantly alter the architecture of their controllers. The Bravera SC5 controllers still include a mix of Arm cores (Cortex-R8, Cortex-M7 and a Cortex-M3), but now includes much more fixed-function hardware to handle the basic tasks of the controller with high throughput and consistently low latency.

Top-of-the-line PCIe 4.0 controllers from Phison [] and Silicon Motion [] are capable of 7.4 GB/s of sequential reads.
