Seagate has resurrected hybrid storage with its FireCuda Forge which crosses a mechanical hard drive with an SSD that buyers must supply themselves.
According to Ars Technica, the outfit is selling 8TB and 20TB versions, using its Alkemi controller to manage the two drives as one storage device. Frequently accessed files get space on the SSD, while less active material stays on the spinning platters.
For those not in the know. Hybrid storage largely fell out of favour when SSD prices dropped. With flash becoming painfully expensive again, an old compromise has acquired a fresh marketing budget.
The Forge connects over USB4 and supports Windows 11 and macOS 26 or later. Seagate claims sequential reads of up to 2,500MB/s and writes of up to 2,000MB/s, figures buyers should avoid confusing with the speed of the mechanical disk.
There are fairly specific rules for the missing SSD. It must be an M.2 2280 NVMe model using PCIe 3.0 or newer, with minimum read speeds of 2,400MB/s and write speeds of 2,000MB/s.
Seagate recommends a drive with DRAM cache and caps supported SSD capacity at 1TB. Even the 20TB version therefore has a relatively small fast section, making the controller’s decisions about what belongs there quite important.
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.”
The storage management happens inside the enclosure, removing the need for the operating system to organise the two tiers. Buyers see one drive and leave Alkemi to decide where their files live.
Unfortunately, Seagate’s enthusiasm for explaining the intelligence exceeds its enthusiasm for explaining what happens when something breaks. Ars Technica found that the launch material leaves the failure and recovery arrangements unclear.
A system that keeps a complete copy on the hard drive has different recovery implications from one that distributes unique data across both devices. An SSD failure could mean losing a performance boost or losing access to files, depending on the design.
That deserves a clear explanation before customers entrust a large library to the enclosure. Calling storage “intelligent” offers little comfort when recovery remains a guessing game. The Forge is available through Seagate’s online shop. Neither capacity includes the required SSD.
