Silicon motion shows its first pcie 4.0 ssd drivers
Table of contents:
Now that AMD's Ryzen 3000 series chips have brought PCIe 4.0 support to the desktop, the race for new and faster SSDs is underway. With strategic partnerships with many popular SSD providers, Silicon Motion has saturated the market with some of the fastest SSD controllers in recent years, and the company had several turnkey solutions as well as custom built designs for companies like Shannon. Systems.
Siicon Motion has its drivers ready for the era of PCIe 4.0 SSDs
On the consumer side, SMI has two new PCIe 4.0 SSD controllers that will arrive next year: The SM2264 and SM2267. Although the SM2267 may lead you to believe that it is faster than the SM2264, it is actually slightly slower due to a four-channel architecture using DRAM, unlike the next-generation DRAMless E19T controller from the competitive Phison. However, the SMI driver uses DRAM, so it dwarfs the Phison driver with read / write speeds of up to 4/3 GB / s and random performance of up to 400, 000 read / write IOPS. It supports the latest 9x layer NAND in TLC and QLC flavors and is set for release next year.
The SM2264, on the other hand, has an eight-channel design and is expected to reach speeds of up to 6.5 GB / s read and 3.9 GB / s write with 700, 000 IOPS. So, slightly less than Phison's recently announced E18 driver, and the SMI driver doesn't seem to support NVMe 1.4 yet. Like the SM2267, it is compatible with the latest NAND technologies and we should see it early next year with capacities up to 16TB, which is double the capacity of the SM2267.

On the data center side, SMI showcased its line of SSDs from Shannon Systems, which includes a number of application-specific devices, such as Key-Value and open channel SSDs. SMI also had some new complete drivers and reference designs such as the SM8108, SM2270 and SM2271 drivers. Interestingly, SMI uses Toshiba's latest XL-Flash, which is quite similar to Samsung's Z-NAND. These new types of flash are gaining ground, so we should see more of them in the future.
