## Summary description

The Sonnet M.2 2x4 Low-profile PCIe Card supports Serial ATA storage drives and features a PCI Express x8 host interface. It is designed for efficient data transfer and storage expansion in compact systems.

## Long description

The Sonnet M.2 2x4 Low-profile PCIe Card (FUS-SSD-2X4-E3S) is an internal expansion card that holds two M.2 2280 NVMe PCIe SSDs and installs in a PCIe x8 slot to add high-capacity, high-speed NVMe storage to desktop, workstation, server, or compatible expansion systems. The card uses an x8 host interface and an internal PCIe bridge to allocate four PCIe lanes to each installed SSD, enabling combined performance and support for up to 16 TB of SSD capacity (dependent on installed SSDs).
Advantages
The card enables ultra-high-speed data transfers by allowing two NVMe SSDs to operate together, including a RAID 0 configuration for increased throughput. Its full-performance design uses an 8-lane (x8) connection and a 16-lane PCIe bridge so each SSD receives dedicated PCIe bandwidth without requiring motherboard PCIe bifurcation. The unit is self-contained, broadly compatible with Mac, Windows, and Linux systems that provide an x8 PCIe slot, and accepts a wide range of M.2 2280 NVMe PCIe SSDs. Included full-height and low-profile brackets provide secure installation in most systems.
Suitable for
High-speed data-intensive workflows (video editing, large file transfers)
Internal storage expansion in desktops, workstations, or servers
Systems needing compact, low-profile PCIe storage solutions
Key specifications
Form factor: Low-profile PCIe card, includes full-height bracket
Interface to host: PCI Express x8 (PCIe 3.0/4.0 compatible)
M.2 support: Two M.2 2280 NVMe PCIe SSDs
RAID support: Configurable as RAID 0 for aggregated throughput (software or system RAID)
Throughput: Up to approximately 6600 MB/s in RAID 0 (system-dependent)
Compatibility: Mac, Windows, Linux systems with an available x8 PCIe slot
How to use
Turn off and unplug the computer, open the chassis, and install two M.2 2280 NVMe SSDs into the card’s M.2 sockets following the card’s installation guides. Mount the card into an available PCIe x8 slot using the appropriate full-height or low-profile bracket and secure it. Power on the system and configure the SSDs in your operating system or RAID utility if you require a RAID 0 set for maximum sequential throughput. Ensure drivers or firmware updates for your operating system and SSDs are applied as needed.
Usage recommendations
To avoid thermal throttling during sustained heavy workloads, install the card where airflow is adequate or use the supplied cooling features. Configure RAID 0 only when performance is the priority and ensure you have appropriate backups, as RAID 0 provides no redundancy.
