Lexar THOR Ultra SSD Launches With 11GB/s Read Speeds on PCIe Gen5

Lexar introduced the THOR Ultra, a new solid-state drive that brings PCIe Gen5 speeds to the mainstream M.2 2280 form factor. This launch matters because it offers high-end sequential read performance at a tier that fits standard desktop and laptop motherboards. Buyers looking for faster load times in games or large file transfers now have a specific hardware option to consider.

Lexar introduces a DRAM-less PCIe Gen5 M.2 2280 drive with up to 11GB/s sequential read speeds

The THOR Ultra relies on a 6nm DRAM-less controller architecture to manage data flow without a dedicated memory buffer. Lexar designed the drive to fit the standard M.2 2280 slot found in most modern PC builds. This configuration allows the drive to maintain a compact profile while delivering significant throughput improvements over previous generation hardware.

Specifications

• Interface: PCIe Gen5 x4
• Form Factor: M.2 2280
• Controller: 6nm DRAM-less
• Max Sequential Read: 11000 MB/s (1TB/2TB/4TB)
• Warranty: 5 years

Sequential read speeds vary by capacity, reaching 9900 MB/s for the 512GB model and 11000 MB/s for the 1TB, 2TB, and 4TB versions. Sequential write speeds hit 5000 MB/s for the 512GB drive and scale up to 10000 MB/s for the larger capacities. Random read performance peaks at 2200K IOPS for the 2TB model, while random write speeds reach 1900K IOPS on the 1TB variant.

The drive includes intelligent SLC Cache technology to boost sustained write performance during heavy data transfers. Lexar backs the THOR Ultra with a five-year warranty across all storage capacities. Endurance ratings range from 350 TBW for the 512GB model to 3000 TBW for the 4TB version.

We looked at HIKSEMI C5000ECO SSD Brings Gen5 Speed earlier while tracking Lexar launches. The THOR Ultra confirms that DRAM-less designs can now compete with buffered drives in sequential throughput metrics. This product establishes a clear performance baseline for next-generation PCIe Gen5 storage solutions.
