Phison X3 SSD Controller Unveiled with 28 GB/s Throughput and 6.8M IOPS

Phison has unveiled the X3 SSD controller, a next-generation storage solution designed to push the boundaries of performance and efficiency. Phison's latest SSD controller introduces higher sequential throughput of up to 28 GB/s and random IOPS reaching 6.8 million, supporting capacities of 2 petabytes per drive at a total power draw of just 7 Watts.

Phison unveils the next-generation X3 storage controller targeting enterprise data centers with massive bandwidth and capacity gains.

The Phison X3 is built for high-end data center applications, leveraging PCIe 6.0 x4 interface to deliver exceptional throughput. It supports up to 28 GB/s of sequential read/write speeds and handles 6.8 million IOPS in random workloads, making it ideal for demanding enterprise environments that require rapid data access and processing.

Spec comparison

One of the standout features of the X3 is its ability to support drives with a maximum capacity of 2 petabytes per unit. Despite this massive storage potential, the controller maintains a total power draw of just 7 Watts, achieving an impressive efficiency rating of 4 GB/s per watt according to Phison's claims.

In addition to the high-performance X3, Phison also introduced the E37T SSD, a DRAM-less PCIe 5.0 controller optimized for power efficiency. The E37T delivers approximately 14.9 GB/s while consuming only 4.5 Watts, which is 2.5 Watts less than its flagship counterpart, the E28 controller.

The X3 controller will begin sampling to customers in December, with volume shipping expected by mid-2027. Meanwhile, drives based on the E37T are set to start shipping this year, offering a more immediate solution for systems requiring efficient PCIe 5.0 storage options.
