Seagate FireCuda Forge Costs $699 and Leaves Out the SSD

Seagate announced the FireCuda Forge on Nov. 10, an external drive that pairs a hard disk of up to 20TB with an M.2 SSD the buyer has to supply. The 8TB version starts at $699 and the 20TB version at $899, and Seagate's press release says both are on sale now through its online store and authorized partners.

What the $699 and $899 buy

The drive presents the hard disk and the SSD to the computer as one volume. Seagate's software, called Alkemi, watches how often files are read and keeps the busy ones on the SSD, according to the release. Seagate says the system "learns how data is used in real-time", so the owner never chooses where a file lives.

The SSD is not in the box. Blocks & Files reported the requirements: an M.2 2280 NVMe drive on PCIe gen3 or faster, with a DRAM cache and no heatsink. Seagate recommends at least 1TB, and the publication reported that capacity beyond that goes unused. The certified list names the Samsung 990 Pro and the Sandisk SN850X.

Configuration	Forge price (from)	Seagate standalone external, per Blocks & Files
8TB	$699	up to $330
20TB	$899	up to $700

By that arithmetic the Forge costs at least $369 more than the 8TB standalone drive and at least $199 more than the 20TB one, before the buyer pays for a 1TB SSD. The comparison uses ceilings on the standalone prices, so the gaps could be larger.

Two speed figures that disagree

The number that matters here is not the headline speed but what sits behind it. Seagate's release quotes up to 2,500MB/s read and 2,000MB/s write over USB4. Blocks & Files gives 2,400MB/s read and 2,000MB/s write. The 100MB/s difference is small, but the release and the trade report do not match.

Blocks & Files set the Forge against the FireCuda 530R, a Seagate internal SSD rated at up to 7,400MB/s read and 6,900MB/s write. The USB4 link caps the Forge at roughly a third of that read speed. Anything the cache misses falls to the hard disk, and the only disk Blocks & Files tied to the product is the 20TB Exos X24, with throughput below 300MB/s. Seagate did not publish a cache-miss figure.

What Seagate and its critics said

Lance Ohara, vice president of Edge IoT Marketing at Seagate, said in the release: "For years, external storage has forced users to choose: speed or scale." The company's pitch is that the Forge removes that choice.

Chris Mellor, storage editor at Blocks & Files, was blunter. He called the setup "a DIY mess" and suggested that leaving the SSD out lets Seagate avoid stocking flash while SSD prices are rising. That second point is his inference, not something Seagate said.

The Forge supports Windows 11 and macOS 26 or later, and the hard disk can be swapped by removing six screws. The release gives no warranty terms and no regional availability beyond saying it varies by market. The next thing to watch is whether Seagate publishes a cache-miss throughput figure, since that is the number that decides what the extra $369 buys.
