ASUS introduced their Hyper M.2 X16 Gen 4 Card at CES 2020. This card is currently aimed at those running AMD’s 3rd generation Ryzen Threadripper processors on a motherboard powered by the TRX40 chipset. This PCI Express 4.0 x16 card has four M.2 PCIe 4.0 x4 slots under an actively cooled heat spreader. A PCIe 4.0 x16 slot can theoretically hit approximately 32 gigabytes per second (GB/s) of bandwidth and this card
Each of the M.2 slots on the card support M.2 2242, 2260, 2280, and 22110 SSDs, so you have plenty of flexibility of when it comes to what drives you want to populate it with. A PCIe 4.0 x16 slot can theoretically hit speeds of up to 32 GB/s (256Gbps), so this card is capable of doing some amazing things. It is also ready for power hungry high-end PCIe 4.0 SSDs as each slots is capable of providing 14 Watts of power. With up to 56 Watts of SSDs possibly being powered by this AIC the cooling fan should now make sense.
Gigabyte on the other-hand was showing off the AORUS RAID SSD AIC adapter GC-4XM2G4 at CES 2020. This PCIe 4 x16 card also supports four PCIe 4.0 drives and is actively cooled. Unpopulated it runs $149.99 at places like Newegg.
Gigabyte had the card up and running in their CES 2020 suite with four Gigabyte AORUS NVMe Gen4 M.2 drives running RAID0 in a stunning demo system.
Want to guess how fast that RAID array was on a 3rd Generation AMD Ryzen Threadripper platform?
How does 19,031 MB/s read and 15,580 MB/s write sound for sequential read/write performance in CrystalDiskMark 6.0.2? Gigabyte has broken the 19 GB/s mark, which is stunning.
