This article covers Dell NVMe PCIe SSDs, including their use cases, technology, server compatibility, and a detailed list of available models.
Key Features of Dell NVMe PCIe SSDs
What is NVMe?
NVMe (Non-Volatile Memory Express) is a high-speed storage protocol designed specifically for SSDs to overcome the limitations of traditional SATA-based drives. Unlike SATA SSDs, which were built on legacy HDD technology, NVMe operates over PCIe (Peripheral Component Interconnect Express), offering lower latency, higher bandwidth, and better parallel processing.
NVMe vs. SATA: Key Differences
Feature | NVMe SSD | SATA SSD |
Interface | PCIe | SATA |
Speed | Up to 7000MB/s (PCIe Gen4) | Max 600MB/s |
Latency | Very Low | Higher |
Ideal Use | AI, HPC, Databases, Servers | General Storage |
What is PCIe?
PCIe (Peripheral Component Interconnect Express) is a high-speed interface used in modern computers to connect various components such as GPUs, network cards, and storage devices. NVMe SSDs take advantage of PCIe lanes, which determine their speed:
PCIe Gen3 vs. Gen4: PCIe Gen4 SSDs offer nearly double the bandwidth of Gen3, making them ideal for enterprise workloads.
Lanes (x1, x4, x8, x16): More lanes = higher speed. NVMe SSDs typically use x4 lanes for optimal performance.
What is M.2?
M.2 is a compact SSD form factor that replaces older SATA and mSATA drives. It allows direct connection to the motherboard, eliminating the need for cables.
Key Characteristics of M.2 SSDs:
Size Variations: M.2 SSDs come in different lengths:
2230, 2242, 2260, 2280, 22110 (e.g., 2280 means 22mm wide, 80mm long).
Connector Types: M.2 SSDs use B-Key, M-Key, or both, determining whether they support SATA, PCIe, or both.
Compatibility: Found in laptops, desktops, and enterprise servers due to their small size and high performance.
What is U.2?
U.2 is another NVMe SSD form factor, mainly used in enterprise servers and storage arrays. It resembles a 2.5" SATA SSD but operates via PCIe, making it ideal for high-capacity, high-speed storage solutions.
Understanding Dell NVMe PCIe SSD Model Numbers and Classifications
Dell NVMe SSDs come with specific labels that indicate their performance, workload type, and security features:
Label | Meaning |
Class 35, Class 40, Class 50 | Performance tiers (Class 50 is the highest) |
Gen4 x4 | PCIe Generation 4 with four lanes for high-speed data transfer |
SED (Self-Encrypting Drive) | Supports hardware encryption for secure data storage |
RI (Read Intensive), MU (Mixed Use), WI (Write Intensive) | Determines workload type |
U.2 | Enterprise-grade high-speed NVMe storage |
Dell NVMe PCIe SSD Example Breakdown
A Dell SSD labeled "M.2 PCIe NVMe Gen 4x4 Class 40 2280 SED 1TB" means:
M.2 PCIe NVMe → NVMe SSD using the PCIe interface
Gen 4x4 → PCIe Gen 4 with four lanes
Class 40 → Mid-tier performance
2280 → 22mm width, 80mm length
SED → Self-encrypting drive for secure data
1TB → Storage capacity
