Sonnet Fusion Dual U.2: two U.2 SSD slots in a PCIe x16 card

Sonnet is a brand known for its outstanding products. Today, it unveils a PCIe card that can accommodate two SSDs using U.2 type connectors (SFF-8639). Enough to increase the storage capacity of your machines with very high speeds.

Sonnet is a manufacturer offering many peripherals and accessories, especially in Thunderbolt. These range from external enclosures to Multi-Gig Ethernet adapters, card readers, docks, etc. Today, he introduces an expansion card … for SSD.

Up to 6.25 Gb / s, from boot on Mac (conditionally)

It is in the format Full-Length Full-Height and has a PCIe 3.0 x16 interface. The connectors for SSDs are U.2, or PCIe 3.0 x4, and a theoretical maximum speed of 4 Gb / s per SSD. In practice, the manufacturer advertises up to 6.25 GB / s in RAID 0.

On top of the Fusion Dual U.2, a “bracket” is installed by default. It is intended to simplify the installation of the card in a 2019 Mac Pro, but can be removed if necessary, it will then be necessary to remove four T8 Torx screws. The fixing of the SSD is for its part ensured by cruciform screws all that it has more traditional.

The card can be used to boot with a Mac Pro 5.1 or 7.1, provided that you only have one SSD installed on it (no RAID). On Windows and Linux, this is not possible, specifies the manufacturer.

Availability is immediate, for a price of $ 199.99 on the manufacturer’s website.

Hot swap PCIe cards for S-ATA and M.2 SSDs at Icy Dock

Note that there are already products of the same kind. Some time ago, Icy Dock presented two references in its ToughArmor range, more geared towards the general public. The first is a PCIe 2.0 x1 card (MB839SP-B) with a 2.5 “hot swap slot for an S-ATA SSD. It is already on sale for 70.50 euros.

The second (MB840M2P-B) has a PCIe 3.0 x4 interface with a “hot swap” bay again for M.2 NVMe (PCIe) 2230 to 22110 SSDs, ie 30 to 110 mm long. It is available for 60 euros at LDLC. The objective was then to integrate storage via such a card while allowing it to be removed hot. Convenient for mini PCs.

As a reminder, you can also opt for a USB 3.1 box without screws for S-ATA / NVMe SSD (read our test).
