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. See M.2 Compatiblity Tab for more details.
  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.

Install Four M.2 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 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.

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!

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 system’s 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.

The ultimate scratch disks for full DaVinci Resolve

Over the last 3 months, editors have increasingly stepped away from the post house to cut, grade and finish from home. Unplugged from ultra-fast online storage, editors have felt the pain of small local drives and storage that isn’t up to the job of multi-channel RAW. The problem is real and becoming increasingly pressing: video resolution is increasing, with 4K and 6K cameras becoming common on the market, and more cameras offering 10-, 12- or 16-bit recording options. For a creative platform like DaVinci Resolve, this additional data is a godsend as it gives editors, colourists and compositors the flexibility to control the look with no creative boundaries.

How to make your Mac Pro work faster with Sonnet (or much faster)

Sonnet Technologies is well known for its Thunderbolt 2 and 3 enabled PCIe expansion boxes but did you know they also produce some amazing PCIe cards too? They can work wonders for your Mac, whether they're installed into the chassis, or attached via a Thunderbolt expansion unit. Sonnet’s Simply Fast 4x4 M.2 PCIe RAID card The Sonnet M.2 4x4 PCIe Gen 3.0 card is an amazing product that can help you create a super fast internal storage array (think 6K or 8K scratch disk) for the new 2019 Mac Pro. Yes, this Super Fast Sonnet Tech card is on Apple's PCIe approved list. Having 16 PCIe lanes, that's 4 PCIe lanes dedicated to each of it’s four M.2 NVMe SSD slots. You'll have to buy those Samsung 970 Pro SSD cards separately, but after you have, you can stripe a RAID 0 across those four M.2 SSDs. That would provide a HUGE 4 TB scratch disk operating at a theoretical max of 8,500 MB per second!
