185 Watts, 12 Bays, 4 Terabytes? TFNEW S655G4
TL;DR: TFNEW launched the S655G4, an enterprise storage server, on September 21, 2026. A 4U storage architecture with an Intel Xeon Ice Lake-SP processor (3rd Gen Scalable, 185 W), 16 DDR4 DIMM slots (up to 4 TB) and 12 front hot-swap drive bays — 12 bays of capacity on a low-power, low-cost compute platform.

Core Specifications (with Plain-Language Terms)
The S655G4 is the efficiency play in TF NEW's 4U storage line: a single Intel Xeon Ice Lake-SP processor (3rd Gen Xeon Scalable) at just 185 W TDP — the low-power end of the Ice Lake range — paired with 16 DDR4 DIMM slots (8 channels per CPU) of ECC RDIMM/LRDIMM up to 3200 MHz and 4 TB. Storage: 12x front 3.5"/2.5" hot-swap SATA/SAS bays plus 2x internal 2.5" SATA/SAS SSDs, with an integrated SATA controller and optional standalone RAID card. Networking: 2x onboard gigabit data ports. The design thesis is simple: for capacity-centric storage duty — archives, backups, media libraries, NAS pools — the workload is I/O-bound, not CPU-bound, so the node pairs twelve bays of capacity with the lowest-power, most cost-effective Xeon Scalable compute available.

Why the Efficient Storage Node Is the Right Economics
Capacity storage doesn't need flagship CPUs — it needs the right CPU for the I/O duty, because every watt spent on compute is a watt not spent on the disk array's real job: holding data reliably. The S655G4 optimizes for that: a 185 W Ice Lake processor is plenty for NAS, backup and archive workloads, while 12 hot-swap bays and 4 TB of ECC DDR4 give the node capacity and metadata room. The result is a storage node whose power bill, acquisition cost and operational simplicity all reflect what storage duty actually requires — the opposite of paying for compute a disk shelf will never use.
Where It Fits
- NAS and file storage pools: 12 bays on efficient, reliable compute
- Backup and archive targets: low-power nodes for write-heavy duty
- Media libraries: capacity-centric storage at low per-node cost
- Branch and edge storage: efficient 4U footprint for distributed sites
Why the Numbers Matter
- 185 W Ice Lake: low-power compute matched to I/O-bound duty
- 12 hot-swap bays: capacity for NAS, backup and archive roles
- 16 DDR4 up to 4 TB: ECC metadata and working-set room
- Integrated SATA + optional RAID: controller choice per array plan
- 2x gigabit: standard connectivity for storage clients
What TF NEW Says
"A storage node should spend its budget on disks, not on CPU it will never use," said a TF NEW product manager. "The S655G4 pairs twelve hot-swap bays with a 185 W Ice Lake processor and 4 TB of ECC DDR4 — capacity-first economics for NAS, backup and archive duty. Twelve bays of reliable storage at the power and cost a disk shelf deserves."
Quality and Availability
Every S655G4 is burn-in tested under sustained I/O — all drive bays, memory channels and PCIe paths validated for 48 hours before shipping. It ships deployment-ready with RAID and storage configuration documentation.
