RAID card delivers impressive speeds up to 56 GB/s — throughput possible with four PCIe 5.0 SSDs or eight PCIe 4.0 SSDs

HighPoint's premiere NVMe Gen 5 RAID controller, the Rocket 1608A.

Those searching for higher performance than the best SSDs can offer may be interested in hearing about HighPoint unveiling the brand's latest RAID controller card, the HighPoint Rocket 1608A. The HighPoint Rocket 1608A is a hardware RAID card that leverages eight PCIe 5.0 / PCIe 4.0 x4 slots (only four full-speed drives can be used at a time if Gen 5), all controlled by a Broadcom PEX89048 chip to drive up to 56 GB/s throughput.

According to Broadcom, the PEX89048 chip is a "48-lane, 48-port, PCI Express Gen 5.0 ExpressFabric Platform." ExpressFabric refers to the technology used to allow for rapid PCIe switching between otherwise standard NVMe drives, making speeds like this possible in a RAID 0 configuration. It is how you're achieving NVMe speeds faster than individual drives with the help of this RAID controller card.
