Seagate FireCuda Forge pairs up to 20TB of HDD storage with a user-supplied SSD

Seagate has announced the FireCuda Forge, an external storage device that combines a high-capacity hard drive with an NVMe SSD supplied by the user. Available with 8TB or 20TB of HDD storage, it uses the company's Alkemi platform to prioritize frequently accessed files on the faster SSD while keeping less-active data on the hard drive.

The crucial purchase detail in the November 10, 2026 announcement is that an SSD is not included. A compatible NVMe drive must be installed for the product to operate. The announced starting prices of $699 for 8TB and $899 for 20TB therefore exclude the SSD. Local pricing and stock availability in Türkiye have not been verified.

Two storage tiers presented as one drive

Alkemi adapts data placement to usage patterns, reducing the need to move files manually between separate storage devices. Seagate says the two tiers appear to the computer as one drive, and the internal HDD can be upgraded later.

That design does not make the entire hard-drive capacity permanently as fast as an SSD. The location of the data and the workload can affect the result. The advertised peak speeds should therefore be treated as maximum specifications, not a guarantee for every transfer or file.

USB4 and SSD requirements

Seagate specifies USB4 connectivity, read speeds of up to 2,500MB/s and writes of up to 2,000MB/s. Supported platforms are Windows 11 and macOS 26 or later. A footnote on the official product page requires an M.2 2280 NVMe SSD using PCIe Gen3 or newer. It lists a 1TB maximum, minimum read/write performance of 2,400/2,000MB/s and recommends DRAM cache.

An independent early test used a larger SSD, but buyers should follow the manufacturer's current compatibility requirements rather than infer unrestricted support from that test. We are not treating a larger installed drive as evidence that any SSD capacity is supported in full.

What the early testing establishes

Tom's Hardware found that, after installing an SSD, the Forge appeared as a single drive in Windows 11 without additional software setup. Its preliminary testing showed gains over conventional hard drives in some workloads, while the publication said more testing, including game loading, was needed before a full verdict.

The Forge is aimed at users keeping large game libraries, footage and projects together. Assessing its value means considering the separate SSD cost, the computer's available USB interface and the nature of the workload alongside headline capacity. An archive accessed occasionally and a project transferring data continuously have different demands.
