It is specifically designed for improving data storage and management on servers and workstations. This card is equipped with Non-Volatile Memory Express (NVMe) technology, which is known for its exceptional speed and reliability in the world of data storage. Additionally, it boasts 8 Gigabytes (GB) of storage capacity and utilizes the Gen4 interface with 16 lanes, providing superior performance.

Understanding PCI-E and Its Significance

Before delving into the specifics of the Dell 405-AAZE PCI-E PERC H755N card, it's essential to understand what PCI-E is and why it's significant.


PCI-E, which stands for Peripheral Component Interconnect Express, is a high-speed interface standard used for connecting various hardware components, such as graphics cards, network adapters, and storage devices, to a computer's motherboard. Unlike its predecessors, PCI and AGP, PCI-E offers several advantages, including faster data transfer rates and greater scalability.

PCI-E is crucial in modern computing for a variety of reasons:

  • Speed: PCI-E offers significantly faster data transfer speeds compared to older interface standards. This speed is especially important for demanding applications, such as gaming, video editing, and data-intensive tasks.
  • Scalability: PCI-E supports different sizes of slots and configurations, making it adaptable to various hardware needs. It comes in different versions, such as x1, x4, x8, and x16, each offering different levels of bandwidth.
  • Compatibility: PCI-E is widely adopted, making it compatible with a broad range of hardware devices. It is the standard interface for modern graphics cards, SSDs, and expansion cards.
  • Reliability: PCI-E is known for its reliability and stability, which is crucial in business-critical environments, including servers and workstations.

Performance Enhancements with Gen4 16 Lanes

The Dell 405-AAZE PCI-E PERC H755N NVME 8GB Gen4 16 Lanes NV Cache Front Controller Card is a Gen4 16 Lanes card, which offers several performance enhancements over previous generations. Here are some ways to take advantage of these enhancements:

  • Utilize NVMe drives: The card is designed to work with NVMe drives, which offer significantly faster read and write speeds compared to traditional SATA or SAS drives.
  • Use RAID 0 or RAID 1: These configurations can help maximize disk input/output operations per second (IOPS) and provide fast and reliable data access.
  • Enable write cache: The card supports a battery-backed write cache (BBWC) option, which can improve write performance and protect data in the event of a power failure.
  • Use the full 16 lanes: Utilizing the full 16 lanes of the Gen4 interface can help increase the overall performance of the system.
  • Upgrade to the latest firmware: The latest firmware may include performance enhancements and bug fixes.

NVME Support and NV Cache

The Dell 405-AAZE PCI-E PERC H755N is an NVMe front controller card that supports NVMe drives. It features an NVMe interface and has a built-in 8GB Gen4 NVMe cache.

NVMe (Non-Volatile Memory Express) is a high-performance, scalable, and optimized interface for solid-state drives (SSDs). NVMe drives provide faster read and write speeds compared to traditional SAS or SATA SSDs, making them ideal for high-performance computing, data center, and enterprise storage solutions.

The 8GB Gen4 NVMe cache provides an additional layer of performance acceleration by enabling faster access to frequently used data. The NVMe cache can improve the overall system performance by reducing the number of disk accesses required for reads and writes, and can also help to absorb write spikes, improving write performance.

It is recommended to check the server's technical guide or contact Dell for specific information about compatibility and usage with your server and storage environment.

Advantages of NVMe

  • Speed: NVMe SSDs can achieve much higher data transfer speeds compared to traditional HDDs and SATA SSDs. They are capable of delivering lower latency and higher input/output operations per second (IOPS), resulting in snappier system performance.
  • Low Latency: NVMe reduces data access latency, making it ideal for applications that require real-time data processing, such as gaming, 3D rendering, and video editing.
  • Efficiency: NVMe SSDs are more power-efficient, which is crucial for laptops and portable devices. They consume less power and generate less heat, extending the lifespan of the hardware.
  • Reliability: NVMe SSDs have a longer lifespan due to their robust design and wear-leveling algorithms, which distribute write and erase cycles evenly across the NAND cells.
  • Scalability: NVMe is highly scalable, allowing for the development of higher-capacity SSDs. It is an ideal choice for data centers and enterprise storage solutions.

The integration of NVMe technology in the Dell 405-AAZE PCI-E PERC H755N card ensures that it can harness the full potential of high-speed NVMe SSDs, making it a valuable addition to any server or workstation.

NV Cache Benefits

  • Speed: NV Cache significantly improves data access speed, making applications and processes run faster and smoother.
  • Reduced Latency: The caching of data in NVMe SSDs reduces data access latency, which is crucial for real-time applications and services.
  • Improved System Responsiveness: The card's NV Cache enhances the overall system's responsiveness, ensuring that users experience a snappy and efficient computing environment.
  • Extended Hardware Lifespan: By reducing the need to frequently access slower storage devices, NV Cache can extend the lifespan of traditional hard drives, SSDs, and the hardware that hosts them.
  • Data Protection: NV Cache can be configured to provide redundancy and data protection, ensuring that critical data remains safe in case of hardware failures.
