People are out here thinking 5GB/s is the fastest we are going to get with PCIe 4.0. Well, they are all wrong. Gigabyte is out here with a solution that triples that speed at 15GB/s. This puts the Corsair MP600 and others to shame. This is achieved through Gigabyte’s quad SSD adapter. It is currently a prototype, but it is slated to come out in the near future as it achieving great functionality.

The purpose of the adapter is to reach maximum functionality of the new bandwidth that technically allows for 64GB of memory bandwidth which is not very attainable. After you add in the annoying, yet unavoidable overhead of the PCIe interface and RAID, Gigabyte’s new prototype has hit up to 15 GB/s when paired with four of the company’s new Aorus PCIe 4.0 SSDs. Each of those SSDs hit up to 5GB/s, so the card could potentially push up to 20 GB/s with further tuning. To reach the max of 64GB/s, theoretically you would have to use 13 SSD with additional tuning which is very expensive and would result in a massive adaptor, but overall 15GB/s is impressive either way.
