Asgard announces AN4, its first SSD with low-cost China 3D NAND

The Asgard AN4 uses an Innogrit IG5236 Rainier controller, but its biggest peculiarity is that it uses 128-layer 3D NAND TLC memory chips from the Chinese manufacturer YMTC, chips that carry their patented technology. Xtacking 2.0. This process involves producing interconnects and the NAND stacks on separate wafers, and then YMTC fuses them aligning the millions of tiny holes by means of a high precision optical system.

Asgard AN4, the first Chinese PCIe 4.0 SSD arrives

To keep cool during operation, the Asgard AN4 features a robust passive heatsink integrated with a dissipation area of ​​up to 8 cm². The manufacturer claims that this heatsink helps reduce operating temperature by as much as 30 ° C, and rates this solid state device with a theoretical performance of up to 7,500 MB / s read speed and 5,500 MB / s read speed, although They have not given data on their random performance.

Asgard touts its AN4 with a high endurance rating, but TBW’s exact values ​​have yet to define them either. The SSD comes with a 5-year limited warranty, and unfortunately the manufacturer has not shared its price either, although they have said that there will be 1 TB models that will hit stores at the end of August and two other 2 TB models and 512GB of capacity that is still in the planning stage, but presumably can be purchased before the end of the year. Another of the curiosities of this SSD is that it has a fairly low cost, so it could become the cheapest SSD of more than 7,000 MB / s on the market.

Performance data

AN4 performance

A user of the forums of the source of this news has already tested (according to him) a 1TB Asgard AN4 SSD. This SSD adheres to the double-sided PCB design with four NAND chips bearing the part number YMN09TC1B1HC6C.

The user pointed out that the AN4 supports a maximum payload size (MPS) of up to 512 bytes, which theoretically allows a transfer speed of up to 7,500 MB / s while other SSDs with support for a 256-byte MPS max out. of 7,150 MB / s. However, a specific motherboard is required to be able to achieve these values, noting that only AMD boards support 512-byte MPS, while Intel Z590 motherboards are limited to 256-byte MPS.

The user compared the AN4 with other SSDs with the same controller but with different NAND TLC chips in the screenshot that you can see above, and the performance differences are obvious, with the Asgard device winning the game by a lot.
