Sonnet M.2 2x4 - 2x M.2 NVMe SSD slots up to 16TB
The Sonnet M.2 2x4 Silent PCIe card allows two NVMe SSDs to be mounted in a single PCIe x8 card slot and combine their capacities, for superior performance. For professional workflows, storage capacity and throughput speed are critical. M.2 NVMe PCIe SSDs offer great performance, but you need to combine multiple SSDs for large storage capacities. The Sonnet M.2 2x4 Silent card is a full-height, full-length PCIe 3.0 card with 8 lanes (x8 interface), designed to dedicate four lanes of PCIe 3.0 bandwidth to each SSD. It does not require a dedicated motherboard to operate, nor specific SSDs to support RAID functions. A Sonnet PCIe expansion system or a free PCIe slot is sufficient to add up to 2 SSDs to Mac, Windows or Linux computers.
Up to 16 TB of SSD storage in a single expansion slot
With the Sonnet M.2 2x4 PCIe card installed in your Mac, Windows or Linux desktop PC or server, or Thunderbolt to PCIe card expansion system, you can use it for instant-access media storage or as a high-performance virtual memory disk. Mac users can even install macOS on an SSD to create an ultra-fast bootable drive and create a RAID 0 array with the other SSDs installed without loss of performance. Whatever you use it for, the performance of this card is impressive.
Sonnet's M.2 2x4 PCIe card is a full height, full length PCIe 3.0 card with an 8-lane (x8) interface. With a unique Sonnet-designed x8 PCIe bridge, the card dedicates four lanes of PCIe 3.0 bandwidth to each SSD you install. When installed in the PCIe 3.0 slot of a Windows PC with two SSDs formatted in a RAID 0 configuration, the card is capable of 3,400MB/s transfers. Aggregate transfer speeds of up to 6,600 MB/s from two non-RAID SSDs are possible.
Sonnet has designed the M.2 2x4 PCIe card with a custom cooling solution that incorporates several components. These include a heatsink and an intelligent fan that monitors temperature and spins only when and at the speed needed to minimise audible noise. Together, they allow SSDs to run for extended periods of time - especially during large file transfers - without thermal throttling of SSD performance.
Sonnet's M.2 2x4 PCIe card is ideal for use in a Sonnet expansion system, such as the Echo Express III-D, III-R or xMac Thunderbolt to PCIe. Integrating a Sonnet M.2 2x4 PCIe card into your system is simple - just insert it into a PCIe x8 slot and power up your computer. NVMe compliance ensures automatic installation of the required drivers. Compatible with macOS 10.13.6+, Windows 10 and Linux, the Sonnet M.2 2x4 PCIe uses the operating systems' built-in drive formatting utilities to format SSDs. Drive health monitoring is also performed via S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data reporting.
