Sonnet M.2 8×4 Silent Gen4 PCIe Card – Product Overview
The Sonnet M.2 8x4 Silent Gen4 PCIe Card is a full-length, full-height PCIe storage card that mounts up to eight M.2 2280 NVMe SSDs in a single x16 slot.
Eight M.2 NVMe SSD Slots
The card supports single-sided and double-sided M.2 2280 NVMe PCIe SSDs, including compatible Gen4 and Gen3 devices. With eight 8TB SSDs installed, raw capacity can reach 64TB.
PCIe 4.0 x16 Architecture
A PCI Express 4.0 x16 host interface and 48-lane PCIe 4.0 switch make full x16 slot bandwidth available across the installed x4-connected SSDs. PCIe bifurcation is not required.
Up To 30,000MB/s Read
In a PCIe 4.0 x16 host, Sonnet specifies up to 30,000MB/s read and 18,000MB/s write with four suitable SSDs configured as RAID 0. In a PCIe 3.0 x16 host, four-drive RAID 0 performance is specified up to 14,000MB/s read and 12,000MB/s write. Actual performance varies with SSDs, host architecture and workload.
Thunderbolt Expansion Compatibility
The card can also be installed in compatible Sonnet Thunderbolt expansion systems with a full-length x16 PCIe slot. Sonnet currently specifies maximum Thunderbolt performance up to 2800MB/s.
Silent Cooling
Sonnet uses a passive thermal design to sustain SSD performance without an onboard cooling fan. SSD health monitoring is supported through S.M.A.R.T. data reporting.
RAID And Boot Support
RAID 0, 1, 5 and 10 are supported according to operating system and software capability; RAID 5 on macOS requires third-party software such as SoftRAID. Booting from a single non-RAIDed SSD is supported on compatible systems.
Auxiliary Power For Seven Or Eight SSDs
When seven or eight SSDs are installed, Sonnet requires the included 6-pin PCIe auxiliary power connection. Auxiliary power is optional with up to six SSDs installed.
