- UTRAN PCIE 5.0 card has 28 m.2 ssds, reaching a total capacity of 224TB
- Offers 109 GB/s reading speed using the Broadcom switch and advanced cooling
- Ideal for AI workloads, but excessive for most business storage needs
Utran Technology has introduced a new PCIE 5.0 complementary card that feels more like a GPU than as a storage solution.
Presented in Computex 2025, the device can house up to 28 NVME GEN5 M.2 8TB SSDS in a single slot, which offers a sequential reading rate of 109 GB/S and a total storage capacity of 224TB.
Two versions of the Host 28x M.2: HM-5281A and HM-5282A card will be available; Both use the Broadcom Atlasii PEX89144 switch to handle internal bandwidth and connectivity. The HM-5281A uses an ascending link PCIE GEN5 X16, while the HM-5282A doubles that with two x16 links, which raises the total bandwidth of up to 1024 GT/s.
Hot plug surprise
Cooling comes through a high pressure and radiator fan combo. Although it has a dense footprint, the design is built for the implementation at the scale of the shelf. In theory, eight cards could deliver almost 1.8pb of flash within a single server.
Both models are executed in an EPS connector of 8 pins and admit a hot surprise cap, which means that the system can detect and manage the units of 28 m.2 even if they are exchanged unexpectedly. This is particularly useful for dynamic tests or environments. However, you will have to be careful in real world implementations, especially because the card itself is not very useful.
The 28x M.2 host card also lacks energy loss protection at the card level, so you must trust SSDs that include your own safeguards.
However, the card admits USB terminal control for firmware updates and system monitoring.
Compatible operating systems include Windows, Windows Server and Linux, which makes it relatively flexible at the software level.
It is difficult to discuss with unprocessed numbers: the 109GB/Sy reading speed The latency of subconacdos are undoubtedly impressive, but out of certain cases of use of HPC or AI, it is frankly difficult to see a wide audience. Even in dense environments, this level of performance could exceed most storage needs.
Utran says he plans to start sending his 28x M.2 host card in the summer of 2025.
