After initially launching it at Computex a little earlier this year, GIGABYTE officially unveiled its quad-SSD PCIe 4.0 adapter card, the AORUS Gen4 AIC. Built with up to 4 NVD SSDs, the card is essentially a multidirectional M.2 adapter that allows a PCIe 4.0 x16 slot to be used to drive four x4 SSDs. Decently, with so many high-end SSDs on a single card, the card also has an active cooling system to ensure that the drives operate at a constant speed even at high loads. Fully populated with PCIe 4.0 SSDs, the card is rated to provide a decent 15GB / s of bandwidth – at least if you can figure out a workload that can saturate such a setup.
The Aorus Gen4 AIC SSD of GIGABYTE 8 TB is a PCIe 4.0 x16 PCB with eight PCIe Gen 4 pre-drivers. The card, in turn, carries four 2 TB M.2-2280 SSDs based on the Phison PS501
When running in RAID 0 mode, the Aorus Gen4 AIC SSD 8 TB offers up to 15 GB / s sequential read / write speeds and 430K / 440K IOPS read / write speeds. Obviously, this is focused on the throughput card, because beyond the difficulty of even coming up with so many IOPS in client load, RAID modes don't really improve IOPS.
While the consistent implementation of the Aorus Gen4 AIC SSD 8 TB seems extremely attractive, there is a foreword. The only support for the PCIe Gen 4 platform today is AMD's Ryzen 3000, and these processors support only 24 PCIe 4.0 lanes: x16 for an optional card, x4 for the NVMe SSD, and x4 for chipset connectivity. As a result, in order to make full use of the card, you have to give up the only PCIe 4.0 x16 slot on the SSD card, which makes it a niche product for systems that do not need a powerful dGPU. Otherwise, installing the device in a PCIe x16 slot controlled by the AMD X570 chipset would cause it to close from the PCIe 4.0 x4 connection between the chipset and the processor.
That said, the Aorus Gen4 AIC SSD 8 TB can be shown in full glory, or in a workstation based on the AMD EPYC 7000 series processor with up to 128 PCIe Gen 4 lanes, or probably in a future high-end desktop a class based on a new generation AMD Threadripper processor.
