High-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 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® or Linux® 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 and create a RAID 0 set with the other installed SSDs without loss of performance. However you use it, this card’s performance is impressive.
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!
No 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 or Linux computer with Thunderbolt 2 or Thunderbolt 3 ports, or Windows PC with Thunderbolt 3 ports.
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 are installed automatically. macOS 10.14.4+, Windows 10, and Linux 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.

Dimensions

  • Height: 10.7 cm (4.2 in)
  • Width: 2.0 cm (0.8 in)
  • Length: 31.2 cm (12.3 in)

Weight

  • 680.0 g (1.50 lbs)

Other Requirements

  • Mac Pro 5,1 (Mid 2010 & Mid 2012) with available full-length x16 PCIe slot
  • Mac Pro 5,1 requires a recommended Metal-compatible graphics card for macOS 10.4 (Mojave).
  • Mac Pro 7,1 (2019) – Use x16 PCIe slot (slot 3, 4, or 5) for full performance
  • PC desktop or server with available full-length, full-height x16 PCIe slot (PCIe 3.0 slot is preferred)
  • Mac computer with Thunderbolt 3 or Thunderbolt 2 ports via a Thunderbolt 3 or 2 to PCIe card expansion system with available full-length x16 PCIe slot
  • Windows computer with Thunderbolt 3 ports via a Thunderbolt 3 to PCIe card expansion system with available full-length x16 PCIe slot
  • Linux computer with Thunderbolt 2 or Thunderbolt 3 ports via a Thunderbolt 2 or 3 to PCIe card expansion system with available full-length x16 PCIe slot

Notes

  • Only 2280 (80mm—the most common length) length M.2 SSDs and with memory components on only the top side are supported. M.2 SSDs longer or shorter than 80mm don’t fit. M.2 SSDs with with components on both sides don’t fit.
  • 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.
  • This product’s performance will vary based on the type and number of SSDs used, the CPU speed (for RAID), and the PCIe architecture.
  • 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.
  • 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.
