Silicon Motion readies SM2264 and SM667 PCIe 4.0 Controllers

Within the same time frame at the Flash Memory Summit, Silicon Motion was showcasing its debut to the PCIe 4.0 SSD controller market. Earlier, I’ve talked about Phison readying two of its newer controllers which were shown in the same summit. Just as PHISON readied its E18 and E19T controllers, SMI has the SM2264 and SM667.

About the SM2264 and SM667 PCIe 4.0 controllers

The two of its controllers are SM2264 and SM667, the latter being the low end.

The Silicon Motion SM2264 is the high-end controller which enables sequential read/ write speeds up to 6.5 GB/s / 3.9 Gb/s with random read/write IOPS up to 700K via eight channels. The lower end SM2267 runs via 4 channels. It delivers theoretical speed up to Sequential read/ write 4GBps / 3GBps and 400k random read/write IOPS. According to another source, these controllers aren’t NVMe 1.4 compliant yet so there is some amount of work left.  The key selling point of these controllers is the ability to pair it with 9x NAND layers with either TLC or QLC.

Interestingly, SMI’s controller has metal plating on it.

Early 2020- Good time for NVMe PCIe 4.0 storage!

Just like the Phison E18 and E19T, this is expected to release by early 2020. So we should be seeing a plethora of PCIe 4.0 NVMe SSDs. Interestingly, Intel Phantom Canyon NUCs are rumoured to have PCIe 4.0 among other new bits. But that’s expected to be launched in the year 2021. Apart from that, there’s really nothing known about Intel’s plans with PCIe 4.0…. yet.
