Phison has announced at CES 2020 that it was able to reduce the footprint of its E12 SSD controller to enable incredibly large-capacity SSDs. The two fantastic SSDs that Phison showed off at CES is an 8 TB M.2 SSD and a 16 TB SATA SSD.

Phison's exclusive PCIe 4.0 support for its SSD controllers has made Phison's controllers stand out from the rest, including OEMs like Samsung and other third-party controller vendors.
