At CES 2020, Phison announced that they were able to reduce the footprint of their E12 SSD controller to enable the deployment of high-capacity SSDs.
Phison introduces its SSDs with up to 8 TB PCIe 4.0 and 16 TB SATA
Users who expect larger SSDs will be pleased with the advances in this area, the storage capacity of solid-state drives. Phison introduced 8TB SSD M.2 and a 16TB SSD SATA.
Phison’s unique PCIe 4.0 support for its SSD drivers has set Phison’s drivers apart from other vendors, including OEMs such as Samsung and other third-party driver vendors.
Phison showed a fantastically large 8 TB SSD M.2, this SSD M.2 uses Phison’s E12 controller. The controller differs from the standard E12 controller we know, because the overall size of the controller was reduced from 28 nm without changing the manufacturing process, Phison named this smaller controller PS5012-E12S. This smaller total controller area allows manufacturers to integrate more NAND flash memory into the device itself.
The device on display features four 96-micron layers QLC memory packages on each side of the device, for a total of eight packages. Each package has a total of 1 TB capacity, making this M.2 unit a total of 8 TB. The E12S controller communicates over a PCIe 4.0 x4 link to achieve speeds of up to 3,500 MB/sec sequential read speed and 3,000 MB/sec sequential write speed. This PCIe 4.0 connection also enables this drive to provide 490,000 / 680,000 IOPS random read/write access.
Phison also showed a 16 TB SATA SSD, which is primarily designed for SSD NAS. As with all SATA drives, the SATA bus limits the overall performance of the drive. Even with the SATA bus limitation, this prototype drive is still capable of delivering up to 550 / 530 MB/s read/write speeds. This prototype drive also offers 95,000 / 90,000 IOPS of random read/write performance. There is no comment about the durability of the two drives.
Phison has made no announcement about the price, but with the current cost of flash at around nine cents per GB, the larger 16TB model could cost up to $1,500. We’ll keep you posted.
