Sonnet M.2 8×4 Silent PCIe 4.0 x16 Card

Speed or capacity? Not too long ago, you had to make a choice between the two. The problem is, for many professional workflows, both are critical. Everyone knows M.2 NVMe PCIe SSDs offer great performance, but limited capacity. Hard drives offer great capacity, but very slow speeds by comparison. What if you could create increased SSD capacity? Sonnet makes it possible, as this card enables you to mount up to eight NVMe SSDs into a single PCIe x16 card slot and combine their capabilities for ultra-performance. This card can transform your workflow.

Add up to 64TB of storage with your own high performance M.2 NVMe SSDs.

Get amazing performance from Gen 4 SSDs.

Install in a computer or Thunderbolt expansion system PCIe x16 slot.

Up to 64TB of fast SSD storage, with up to 30,000 MB/s with the 2023 M2 chip and up to 14,000 MB/s with a 2019 Intel chip.

Create an incredibly fast media storage or scratch drive.

Connect eight SSDs to your computer via a single cable with a maximum performance of 2800 MB/s.

Install this card with your SSDs into your computer’s PCIe 4.0 x16 slot to achieve superior storage performance with four SSDs configured as RAID 0. Get read speeds of up to 30,000 MB/s and write speeds of up to 18,000 MB/s.

Install this card with your SSDs into your computer’s PCIe 3.0 x16 slot to achieve outstanding storage performance with four SSDs configured as RAID 0. Get read speeds of up to 14,000 MB/s and write speeds of up to 12,000 MB/s.

The Sonnet M.2 8×4 Silent PCIe 4.0 Card is a full-height, full-length card with a 48-lane PCIe 4.0 switch and x16 interface, designed to support maximum performance. Sonnet M.2 8×4 card features include:

48-Lane PCIe 4.0 Switch
x16 slot bandwidth is available to all x4-connected SSDs, facilitating maximum speed with any combination of M.2 SSDs used

Self-Contained
Doesn’t require a specific motherboard to operate or specific SSDs to support RAID features, no PCIe bifurcation required

Universal Compatibility with Mac, Windows, and Linux
Compatible with Mac, Windows, and Linux computers with an x16 PCIe slot

Broad M.2 NVMe SSD Support
Works with a wide variety of M.2 NVMe Gen4 and Gen3 SSDs

Supports RAID 0, 1, and 10 with macOS, Windows, and Linux.

Supports from single (non-RAIDed) attached SSDs.

Custom silent cooling solution enables installed SSDs to maintain consistent high performance during very large file transfer operations without the use of fans.

No drivers required.

Supports S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data reporting.

Are you an Adobe After Effects user? Imagine being able to perform 4K/60p work in 32-bit linear, or even 4K/24p with high channel count EXRs (or effects in 8K) where your computer’s onboard storage couldn’t keep up. This card makes that possible.

Sonnet designed the M.2 8×4 Silent PCIe 4.0 Card with an effective passive cooling solution. Instead of relying on fans that can get loud, Sonnet’s silent cooling effectively presents thermal throttling, enabling SSDS to maintain sustained peak performance without a peep.

Got a Thunderbolt connection, but no PCIe card slot? This card is ideal for use in Sonnet’s Echo I Desktop PCIe Expansion System. The combo effectively enables you to add up to eight SSDs to any Mac (M series or Intel), Windows, or Linux computer with Thunderbolt ports.

Integrating this card into your system is easy. NVMe compliance ensures the necessary drivers are installed automatically. The M.2 8×4 uses your computer’s operating system’s built-in drive formatting utilities to format the SSDs. SSD health monitoring is supported through S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data reporting, too.

• Windows computer with available full-length, full-height x16 PCIe slot (PCIe 4.0 slot preferred; PCIe bifurcation not required)
• Windows 11 and 10
• Windows Server 2022, 2019

• Linux computer with available full-length, full-height x16 PCIe slot (PCIe 4.0 slot preferred; PCIe bifurcation not required)
• Linux Kernel 5.0+

• With card installed in a Thunderbolt expansion system with full-length x16 PCIe slot
• Any Mac, Windows, or Linux computer with Thunderbolt

When seven or eight SSDs are installed on this card, connecting the included 6-pin PCIe auxiliary power cable between the computer’s and the card’s power connectors is required (optional when up to six SSDs installed).

• Western Digital PCIe Gen4 SSDs are NOT compatible
