InnoGrit unveils budget SSD controller that will deliver flagship speeds up to 7 GB / s

Earlier we talked about the SSD on the new flagship controllers of the Chinese company InnoGrit. Now in the arsenal of InnoGrit appeared budget controller, but it can work at very high speeds, not inferior to the flagship solutions. True, this will have to wait for the release of faster NAND flash chips, which should happen next year.

Sources say InnoGrit has unveiled its first SSD controller that combines low cost and high performance. This is the Rainier IG5221 QX SSD solution with reduced NAND memory channels, but with a higher data bus frequency.

The IG5221 controller currently supports 3D NAND with interface speeds up to 1600 MT / s (megatransactions per second), but after certification of next generation NAND memory with bus speeds up to 2400 MT / s will be compatible also with her. This will allow the release of budget SSDs with an established speed of up to 7 GB / s. The same is stated for modern flagships on the older and more expensive controller of the Rainier IG5236 family.

The flagship controller works with 1200 MT / s memory bus. High performance is achieved due to 8 memory channels, while the budget IG5221 has half the channels for connection. This simplifies the architecture and operation of the chip, making it cheaper. But due to the higher speed, it will not lose in access speed.

The rest of the budget controller has a lot in common with the flagship: it is also produced using a 12nm process technology, supports four PCIe 4.0 lanes with NVMe 1.4 specifications. Probably, IG5221 has the same computing cores as the flagship and the same error correction algorithm. In addition, the simplified structure made it possible to make the body of the junior chip smaller, as well as reduce the consumption to 2.5 W at the peak.

The IG5221 controller can be used to create drives with capacities up to 8 TB, with sequential read speed up to 7 GB / s and sequential write up to 6 GB / s. For random operations, the performance of the solution will be 800 thousand IOPS when reading and up to 600 thousand random IOPS when writing. On the SSD market based on new items promise to appear by the end of this year or early next.
