In the contemporary landscape of cloud computing, storage technology plays a pivotal role.

ServerCloud, staying ahead of the curve, has adopted cutting-edge NVMe storage solutions and PCIe 5.0 interfaces in their AMD Zen 4 systems. This article delves into the technical specifics of PCIe standards, the performance of NVMe storage devices, and why ServerCloud’s approach represents a significant leap in cloud computing technology.

Understanding PCIe Standards: 3.0, 4.0, and 5.0

PCIe (Peripheral Component Interconnect Express) is a high-speed interface standard for connecting high-speed components. Each new version doubles the bandwidth of the previous one, significantly impacting storage performance.

PCIe 3.0: Offers 8 GT/s (GigaTransfers per second) per lane, with a maximum of 16 lanes (x16), resulting in a total bandwidth of 32 GB/s (Gigabytes per second).

PCIe 4.0: Doubles the bandwidth to 16 GT/s per lane. With 16 lanes, this means a total bandwidth of 64 GB/s, effectively doubling the data transfer rates compared to PCIe 3.0.

PCIe 5.0: ServerCloud’s AMD Zen 4 systems utilize PCIe 5.0, which again doubles the bandwidth to 32 GT/s per lane. A x16 configuration yields an impressive 128 GB/s, offering unparalleled data transfer speeds suitable for the most demanding applications.

NVMe Storage: Performance and Efficiency

NVMe drives, compared to older SATA-based SSDs, offer substantial improvements in speed, efficiency, and IOPs. ServerCloud’s choice of Samsung PM9A3 and PM1733 series drives are prime examples:

Samsung PM9A3: Offers sequential read speeds up to 6,800 MB/s and write speeds up to 4,000 MB/s. Random read/write IOPs can reach up to 1,000,000/180,000 IOPs.

Samsung PM1733: Known for its exceptional performance, with sequential read speeds of up to 7,000 MB/s and write speeds of up to 3,500 MB/s. Random read/write IOPs are even higher, 1,500,000 and 135,000 (respectively) making it perfect for intensive data center workloads.

The Impact of Hot-Swap U.2 Interfaces

Incorporating hot-swap U.2 interfaces in ServerCloud’s storage solutions offers several benefits:

Enhanced System Uptime: By allowing storage devices to be replaced or upgraded without system downtime, hot-swap capabilities ensure continuous system operation.

Simplified Maintenance: These interfaces make it easier to manage and maintain storage infrastructure, reducing the complexity and risk involved in storage management.

Scalability and Flexibility: They provide the ability to adapt and scale storage resources quickly in response to changing demands, a crucial factor in cloud computing environments.

Many service providers utilize less expensive M.2 NVMe, which retain fixed positions inside of server chassis, and are not serviceable without downtime.

ServerCloud’s Vision and Commitment

Brad Mitchell, CEO of ServerCloud, with over two decades of industry experience, comments on this technological advancement: “At ServerCloud, we’re not just adapting to technological changes; we’re leading them. The adoption of PCIe 5.0 in our AMD Zen 4 Ryzen and EPYC systems and the selection of the latest NVMe storage devices underscore our commitment to delivering top-tier performance and reliability. Our approach is to provide our clients with the most advanced and efficient solutions, ensuring they stay at the forefront of their respective industries.”


The transition from PCIe 3.0 to 4.0 and now to 5.0 in ServerCloud’s systems, combined with the superior performance of NVMe storage devices, marks a significant evolution in cloud computing technology. ServerCloud’s commitment to leveraging these advancements highlights their dedication to offering the best in terms of speed, efficiency, and reliability, cementing their position as a leader in the cloud computing space.
