The Asgard AN4+ is a solid-state drive in the M.2 2280 form factor, launched in 2023. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Asgard AN4+ interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the MAP1602A Falcon Lite from MaxioTech, a DRAM cache is not available. Asgard has installed 232-layer TLC NAND flash on the AN4+, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 320 GB, once it is full, writes complete at 2300 MB/s. Copying data out of the SLC cache (folding) completes at 800 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The AN4+ is rated for sequential read speeds of up to 7,000 MB/s and 6,500 MB/s write.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Asgard guarantees an endurance rating of 1200 TBW, a typical value for consumer SSDs.
