Product Specifications

The Dell Boss S2 PCI-E 2x M.2 Slots Standard FH Controller Card is a hardware component that offers additional storage capacity to computer systems that have limited storage options. The card is designed to fit into a PCI-E expansion slot on a computer motherboard and provides support for two M.2 solid-state drives (SSDs). In this article, we will discuss the features and benefits of the 403-BCMD Dell Boss S2 PCI-E 2x M.2 Slots Standard FH Controller Card.


The Dell Boss S2 PCI-E 2x M.2 Slots Standard FH Controller Card offers several features that make it an attractive storage solution for computer systems. These features include:

  • PCI-E 3.0 Interface: The card uses a PCI-E 3.0 interface, which provides high-speed data transfer rates. This interface offers a maximum data transfer rate of 8 GT/s per lane, which is twice the speed of PCI-E 2.0.
  • Two M.2 NVMe SSD Slots: The card supports two M.2 NVMe SSDs, which can be configured in RAID 0, RAID 1, or JBOD modes. These SSDs offer high-speed data transfer rates and low latency, making them ideal for use in high-performance computing applications.
  • Standard FH Form Factor: The card has a standard FH form factor, which means that it can fit into a full-height PCI-E slot. This makes it easy to install in most desktop and server systems.

What is the primary function of a PCI e controller?

The primary function of the PCI e controller on your computer device is that it serves as the standard interface between your device's primary circuit board, and other external, peripheral components. This affects key areas of your device's functionality, such as graphics, memory, and storage ability.

The PCIe controller is built to oversee point-to-point connections in the context of non-core components. The additional "e" in PCI-e is short for "express", which is a term that was added by manufacturers in a bid to distinguish the new standard of PCIe controllers from the older PCI models.

The supporting PCIe size simply means the number of direct connections that a PCIe slot or card can provide. It can be PCIe x1, PCIe x4, PCIe x8, and PCIe x16. The cutting-edge PCIe 4.0 has a bandwidth capacity of 64 gigabytes per second and transfers at a rate of 16 gigatransfers per second (GT/s).

Why is a good PCIe controller so important?

  • Connectivity: A PCIe controller is a vital link between your computer's primary circuit board and other peripheral components. This important function makes this little device indispensable.
  • Speed: A PCIe controller impacts speed. Changing the PCIe controller notably improves transfer speeds, drastically increasing the amount of data that can be communicated in a second.
  • Upgrades: Multiple PCI express slots present an exciting opportunity for big upgrades in the future.

Some common PCI e controller terms

  • Expander card: PCIe card, expansion card, and expander card are all common terms used to refer to hardware, some of which include the Central Processing Unit (CPU), graphics card, or SSDs.
  • Host Bus Adapter: This device connects your computer to other networks and storage devices, with your computer playing the role of the host system.
  • RAID controller: This device oversees the hard disk drives and translates them into a logical language your computer can understand.
