Title: How 8x Gen 3 SSDs on the SSD7540/SSD7580A can reach 24GB/s
Applicable Product: SSD7540, SSD7580A
HighPoint 8-Port PCIe Gen 4 NVMe RAID controllers are ideal bandwidth upgrades for applications that need to make the most of existing PCIe 3.0 NVMe storage.
The PCIe Gen4 x16 transfer bandwidth doubles what is possible with PCIe Gen 3; it allows each Gen3 NVMe to operate at peak performance (up to 3000MB/s). Eight Gen3 NVME SSDs, configured as a RAID 0 array, are capable of delivering up to 24GB/s of performance when paired with an SSD7540 or SSD7580A, and a dedicated PCIe 4.0 x16 slot.
A PCIe 3.0 x16 slot hosting the same controller and drives would bottleneck the transfer bandwidth to 14GB/s.
Please check the compatibility reports we provide for each controller – we’ve compile a list of tested Gen 4 motherboards and Gen3 SSD’s:
SSD7540 – 8x M.2 PCIe Gen4 x16 NVMe RAID Controller
SSD7580A – 8x U.2 PCIe Gen4 x16 NVMe RAID Controller
