Install Two U.2 NVMe SSDS Into a PCIe Card Slot – Ultra-fast Data Transfers
If you need more storage capacity for your computer, and super high-speed throughput plus maximum IOPS (Input/Output Operations Per Second) performance are critical to your work, you need an internal NVMe SSD-based upgrade—U.2 NVMe PCIe SSDs deliver both, but you need an adapter to use them. Sonnet’s Fusion™ Dual U.2 SSD PCIe card enables you to upgrade your system in a flash, mounting two enterprise class U.2 SSDs (sold separately) with up to 32TB capacity in a single full-length x16 PCIe card slot, with no separate power or data cables, drive adapters, or mounting trays required.
Use the Sonnet card for instant-access media storage or as a high-performance scratch disk in your Mac Pro® tower; Windows® or Linux® PC desktop or server; or Thunderbolt™ to PCIe card expansion system with an available x16 PCIe slot. Legacy Mac® users can install macOS® on one SSD to create an incredibly fast boot drive and use the other installed SSD for and still obtain blazing-fast performance.
