Install Four M.2 NVMe SSDs Into a PCIe Card Slot

x16 PCIe SlotHigh-speed Data Transfers

If you need to add internal storage to your computer setup and high-speed data transfers are critical to your work, don’t look to 2.5" SATA SSDs—you need an NVMe SSD-based upgrade. Today’s NVMe PCIe SSDs offer tremendous performance, easily outclassing 2.5" SATA SSDs. Sonnet’s M.2 4x4 PCIe card enables you to mount four M.2 NVMe PCIe SSDs(1) onto a single x16 card slot—it can transform the way you work.

With the Sonnet M.2 4x4 PCIe card installed in your Mac Pro® tower; Windows® PC desktop or server; or Thunderbolt™ to PCIe card expansion system with an available x16 PCIe slot, you can use it for instant-access media storage or as a high-performance scratch disk. Mac® users can even install macOS® on one SSD to create an incredibly fast boot drive.(2) However you use it, this card’s performance is impressive.

Sonnet M.2 4x4 PCIe Card

Performance Oriented

Sonnet’s M.2 4x4 PCIe card is a full-height, full-length PCIe 3.0 card with a 16-lane (x16) interface. Featuring a unique Sonnet-designed x16 PCIe bridge, the card devotes four lanes of PCIe 3.0 bandwidth to each SSD you install. When installed in a Windows PC’s PCIe 3.0 slot with four SSDs formatted in a RAID 0 configuration, the card is capable of 8,500 MB/s transfers. Aggregate transfer speeds from four non-RAIDed SSDs of up to 12,000 MB/s are possible! 

Four Lanes of PCIe 3.0 Bandwidth

Key Features

Adds Ultra-Fast SSDs to Your System—Mounts four M.2 NVME SSDs (sold separately) in your computer’s, or Thunderbolt expansion chassis' x16 PCIe slot

High-Performance PCIe Interface—PCI Express 3.0 x16 host bus interface for high-performance applications

Superior Performance—Concurrent data transfers speeds up to 12,000 MB/sec(3)

Great Way to Add Up to 8TB of M.2 SSD Storage to Computers with Thunderbolt—Perfect for use in Sonnet's Echo™ Express III-D, Echo Express III-R, xMac™ mini Server, xMac Pro Server, and Thunderbolt expansion systems

RAID Support—Supports macOS and Windows RAID 0; macOS supports RAID 5 with the addition of SoftRAID

macOS Boot Support—Supports booting from JBOD (non-RAIDed) attached SSDs

Concatenation Support—Mac and Windows support concatenating all 4 SSDs into a single large volume

NVMe Compliant SSDs—Typically no drivers required(4)

S.M.A.R.T. Support—Supports S.M.A.R.T. data reporting

Smart Fan—The fan is temperature-controlled and spins only when and as fast as needed, minimizing audible noise

x16 PCIe Slot

Sonnet card installed in slot 3, four 1TB Samsung 970 EVO SSDs installed on the card and APFS-formatted; 64GB test file size

Install the M.2 4x4 PCIe card with your SSDs into your 2010 or 2012 Mac Pro tower to obtain performance you never thought possible. Planning to upgrade to a 2019 Mac Pro? Move the Sonnet card into it and see even greater performance!

iMac with Echo Express III-DNo Slowdowns

Sonnet designed the M.2 4x4 PCIe Card with a custom cooling solution incorporating several components. These include a heatsink, and a smart fan that is temperature-controlled and spins only when and as fast as needed to minimize audible noise. Together, they enable your SSDs to operate for sustained periods—most importantly during large file transfers—without thermal throttling of the SSDs’ performance, a problem encountered by competing products.

Thunderbolt Port? Connect Four SSDs Through One Cable

Got a Thunderbolt connection, but no PCIe card slot? Sonnet’s M.2 4x4 PCIe card is ideal for use in one of our Echo™ Express III-D, III-R, or xMac™ Thunderbolt to PCIe card expansion systems—the combo enables you to add up to four SSDs to any Mac with Thunderbolt 2 or Thunderbolt 3 ports, or Windows PC with Thunderbolt 3 ports.(5) 

Simple and S.M.A.R.T

Integrating a Sonnet M.2 4x4 PCIe card into your system is easy—just insert it into a x16 PCIe slot and then start your computer—NVMe compliance ensures the necessary drivers(4) are installed automatically. macOS 10.14.4+ and Windows 10 compatible; the Sonnet M.2 4x4 PCIe uses the operating systems built-in drive formatting utilities to format the SSDs. Drive health monitoring is supported through S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data reporting, too.

Technical Notes

  1. Only 2280 (80mm–the most common length) length M.2 SSDs and with memory components on only the top side are supported. M.2 SSD longer or shorter than 80mm don’t fit. M.2 SSDs with with components on both sides don’t fit.
  2. Booting from an external SSD in macOS 10.14.4+ requires enabling external booting in the security preferences that can be set in a command-R (recovery system) boot.
  3. This product’s performance will vary based on the type and number of SSDs used, the CPU speed (for RAID), and the PCIe architecture.
  4. Use of Samsung SSDs in computers running Windows requires the download and installation of NVMe drivers from Samsung; Microsoft Windows inbox NVMe drivers do not support Samsung SSDs.
  5. Performance in a Thunderbolt 3 PCIe expansion chassis limited by maximum Thunderbolt 3 PCIe bandwidth of 2800 MB/s. PCIe bandwidth of Thunderbolt 2 is about half of Thunderbolt 3.
  6. Mac Pro 5,1 requires a recommended Metal-compatible graphics card for macOS 10.4 (Mojave).
  7. SoftRAID Software sold separately.
