Team Group T-Force Z54E PCIe 5.0 SSD aims for 14,900 MB/s with Phison E28 controller
Team Group is raising the bar for PCIe 5.0 storage with its new flagship mainstream drive, the T-Force Z54E. Built around Phison’s latest E28 controller manufactured on TSMC’s 6nm process and paired with 232-layer 3D TLC NAND, the Z54E is designed to deliver top-tier sequential performance while maintaining strong power efficiency.
The company cites peak speeds of up to 14,900 MB/s for sequential reads and up to 14,000 MB/s for sequential writes on the 2 TB and 4 TB models. The 1 TB version is listed at up to 14,900 MB/s read and 13,700 MB/s write. Those numbers put the Z54E at the front of the current PCIe 5.0 pack, where most drives typically land between 10 and 14 GB/s. As always, real-world results will vary depending on your platform, workloads, and thermals.
Thermal performance is a key factor for Gen5 SSDs, and Team Group addresses this with its ultra-thin graphene heatsink to help sustain high speeds under load. Users can also add additional cooling solutions for even more consistent results. It’s worth noting that system-level variables—such as motherboard implementation, CPU platform behavior, and case airflow—can influence throughput and sustained performance on PCIe 5.0 storage.
Positioned as a flagship option for enthusiasts, creators, and professionals, the T-Force Z54E focuses on best-in-class sequential performance on mainstream platforms without sacrificing efficiency. Capacities include 1 TB, 2 TB, and 4 TB, with the highest ratings reserved for the 2 TB and 4 TB models.
Key highlights:
– Phison E28 controller on TSMC 6nm
– 232-layer 3D TLC NAND
– Up to 14,900 MB/s reads and 14,000 MB/s writes (2 TB/4 TB)
– Up to 14,900 MB/s reads and 13,700 MB/s writes (1 TB)
– Ultra-thin graphene heatsink for better thermals
– PCIe 5.0 performance targeting leading sequential speeds
If you’re building a high-end system and want one of the fastest PCIe 5.0 SSDs available on paper, the T-Force Z54E is shaping up to be a standout contender.
