The FireCuda Forge is available right now through Seagate’s web store, and comes in 8TB ($699) or 20TB ($899) HDD configurations—neither of which includes the required SSD. Users will have to bring their own SSD, with some specific restrictions. The FireCuda Forge is compatible with M.2 2280 NVMe drives that are PCIe Gen3 or higher. The maximum supported NVMe capacity is 1TB, which means that’s as much data as you’ll be able to dedicate to storage on the “fast side” of the hybrid setup. The NVMe will require minimum speeds of 2,400MB/s read and 2,000MB/s write, and a unit with DRAM cache is recommended. Seagate claims 2,500MB/s read and 2,000MB/s write speeds for the combined system, along with USB4 and support for Windows 11 and macOS 26+.
After dipping to historical lows earlier in the decade, storage pricing per TB has exploded amid the AI boom. According to data collected by Tom’s Hardware, some solid-state drives now cost two to three times their historic lows, and it’s not just SSDs. Mechanical drives haven’t been immune either. According to PCServerParts, a Seagate Exos 24TB drive that sold for $298.99 in the summer of 2025 was priced at $699.99 by August 2026.
Hybrid drives had largely fallen out of fashion since their heyday in the early to mid 2010s. The promise then was similar to what Seagate is offering now. A large HDD is combined with a smaller SSD and handed to the user as a single storage pool. Apple introduced its own hybrid solution back in 2012 with the Mac mini’s Fusion Drive. When Ars opened up a unit, the Fusion Drive system was found to write in 128KB tiered blocks. Information was generally written to the SSD first, and was then migrated to the HDD as needed. If the files were frequently used, they might find a more permanent home on the SSD side of things.
As solid-state storage continued getting cheaper, the hybrid approach was largely abandoned. Fast-forward to our current storage cost predicament in 2026, and Seagate’s line of thinking that everything old is new again starts to hold water. All storage costs have exploded, but the 2012 math still works today. NAND flash is still fast, but expensive, and traditional mechanical drives are at least comparatively cheaper per TB for higher capacity storage.
The problem with Apple’s Fusion solution was its fragility. If one of the two drives failed, that was likely it. Recovery depended on both drives coming together as a single volume. If one of those two disks experienced a physical failure, recovery became difficult since the remaining working drive depended on the now broken drive’s data to rebuild the full system picture.
According to Seagate’s press release, the Alkemi intelligent storage platform takes a different approach. Where Apple’s Fusion Drives used tiering managed by macOS, Alkemi manages the storage pool directly from the enclosure. Seagate says, “Alkemi learns and adapts over time to keep high-demand content fast and accessible on a user’s SSD, while the HDD provides space for growing libraries. Behind the scenes, Alkemi manages data placement, giving users the simplicity of a single storage drive.” The product data sheet PDF from the FireCuda Forge website describes the Alkemi system as a two-tier storage system, but doesn’t elaborate any further on whether the system uses SSD caching, automated tiering, a combination of the two, or something else entirely.
The announcement doesn’t address how the Alkemi platform manages the data between the two drives. The old Intel Smart Response Technology kept failure risks low by mirroring data from the mechanical HDD to the faster SSD, with the HDD retaining the authoritative copy. The optional write-back mode could still hold new data on the SSD, though. Apple’s Fusion Drive instead tiered data in 128KB blocks across the storage pool, storing data on both drives. The distinction matters, and is probably why Ars asked the same question after Apple’s hybrid announcement 14 years ago.
Seagate’s announcement speaks of “intelligent data tiering” without further explanation. The data system promises that your most accessed files will be quickest to access via intelligent storage management, but stops short of explaining whether one drive going down means failure for the whole system. There’s also no mention of how the Alkemi system distributes data on first boot. Does all the new written data go directly to the SSD until the 1TB cap is crossed, and then the system starts determining which files are important enough to remain on the speedier drive? Seagate seems to be keeping things mum for the moment, but as the drives have already launched for sale, there should be answers to all of these questions coming soon.
Seagate hasn’t published technical documentation regarding how the Alkemi system handles drive failure or repair. Until it does, the new FireCuda Forge drives offer the same appeal as Apple’s old Fusion Drives: SSD speed with HDD capacity, along with the same questions Ars was asking about hybrid storage years ago.
