M.2 NVMe PCIe SSD Expansion
This M.2 2x4 PCIe card allows you to install up to two of your own double-sided M.2 NVMe solid-state drives, for a total of 16TB, into a single PCIe 3.0 x8 slot.
High-Speed Storage
The PCIe 3.0 x8 host bus interface provides four lanes of bandwidth to the installed SSDs for maximum performance. Sustained data transfer speeds can reach up to 6600 MB/s in RAID 0 mode and 3400 MB/s from individual SSDs.
RAID Support
Connected solid-state drives may be put into RAID 0 or 1 configuration.
Compact Design
This PCIe x8 adapter includes both low-profile and full-height brackets, allowing it to be installed into most computer systems and compatible enclosures.
Cool Operation
The M.2 2x4 card's cooling design allows it to stay silent while helping avoid speed throttling during large file transfers.
Optimized for Thunderbolt 3
This PCIe card is compatible with separately purchased Sonnet Thunderbolt 3 expansion systems, which can transfer up to 2800 MB/s through a single cable.
macOS Booting
Supports booting from a single (non-RAID) attached SSD.
SMART Operation
Supports SMART (Self-Monitoring, Analysis and Reporting Technology) data reporting.

Sonnet FUS-SSD-2X4-E3S Reviews

DO NOT BUY! Complete waste of money and time.

There are absolutely NO advantages to pick up this card instead of a no-name one from China. It does NOT deliver on the advertised speeds. Regardless of populating with either a single or two NVMEs, the write speed is consistently 100Mb/s SLOWER than the $29 dumb OWC 1M2 cards I also have in my Sonnet Thunderbolt 3 enclosure. All testing done with the same WD Digital Black SN750 NVME.) Running as a RAID, the Sonnet card was no faster. To put this in perspective, Sonnet states on their website (on their M.2 Compatibility chart) that this same memory slab achieved 2900 Mb/s (non-RAID) Write in their enclosure. The reason I purchased the Sonnet card is because I logically expected that all the extra electronics on their card (as opposed to the OWC dumb one) would unlock the true speed of the WD slab. Nope! Nothing do with any TB3 bandwidth restrictions as I also purchase a WD Digital SN780X and it runs at 2800Mb/s right out of the box no matter which card it is installed on.
