Seagate is releasing its first PCI-E 4.0 SSDs. This is the FireCuda 520, which is available in capacities of 500GB, 1TB, and 2TB. The SSDs use TLC NAND memory that consists of 96 layers and are equipped with the Phison PS5016-E16 controller.
The controller in the Seagate FireCuda 520 SSDs is the same as in the PCI-E 4.0 SSDs from other manufacturers. Also with regard to other specifications and prices, the Seagate SSDs are comparable to those of competitors. Earlier this year, Corsair, Gigabyte, XPG, and Patriot already released PCI-E 4.0 SSDs.
To take full advantage of the PCI-e 4.0 ssds, they must be combined with an AMD X570 motherboard. That is currently the only platform with PCI-e 4.0 support. Seagate does not provide the FireCuda with a heat sink. Many other manufacturers do, but X570 motherboards often already have solutions for cooling NVME-SSDs.
Phison and Silicon Motion have already announced new controllers that should enable speeds of up to 7GB / s. However, SSDs with those controllers are not expected until next year.

Seagate also comes with the FireCuda Gaming Dock . That is a Thunderbolt 3 dock with a 4TB HDD and an expansion slot for a PCI-E 3.0 NVME SSD. The dock has a display port 1.4 connection, an Ethernet port, audio inputs and outputs, and four USB 3.1 ports. The dock is also equipped with LEDs that can be controlled with the supplied software. The dock comes out in the Netherlands for 400 euros and in Belgium for 430 euros.
