The Innogrit’s IG5236 Rainier SSD controller is really making a name for itself. Check out the review of the Patriot Viper VP4300 which uses the same amazing SSD controller.
Taken from TPU … Chinese manufacturer Asgard has announced the company’s (and the Chinese market’s) first PCIe 4.0 SSD. The AN4 pairs 128 Layer 3D TLC NAND manufactured by YMTC (Yangtze Memory Technologies Co., Ltd) Xtacking 2.0 technology, which uses a two-step manufacturing process wherein both NAND cells and interconnects are manufactured in two separate wafers and then optically fused. The NAND memory is then paired with Innogrit’s IG5236 Rainier controller. The AN4 is rated for 7,500 MB/s and 5,500 MB/s sequential read and write speeds and features a “high” TBW endurance rating, though Asgard didn’t clarify the exact random performance figures, nor the TBW rating for the SSD. Pricing is similarly up in the air – Asgard has only announced market availability for the 1 TB SSD solution come August, with additional 2 TB and 512 GB capacities being readied to market for a later timeframe.
The manufacturing technology of YMTC results in NAND that’s as fast as Micron’s latest 192-layer NAND tech, and beats well-established Kioxia’s 96-layer technology performance-wise. One Bilibili forum user put the drive through its paces, and discovered that to unlock its full potential, one has to have a system capable of 512 bit maximum payload size (MPS), which is currently only supported by AMD motherboards – maximum Intel MPS currently stands at 256 bit, which “only” enables sequential performance of up to 7,150 MB/s. The user put the AN4 through a variety of tests, including PCMark 10’s Drive Performance Consistency Test – a 10 to 20 hours workload marathon that puts more than 23 TB of drives on the SSD. It seems that Chinese manufacturers have achieved parity with the top western manufacturers, meaning there is one more option in the global, high-performance NAND market.
