Team Group

Team Group T-Force GA PRO 4TB M.2 2280 PCIe 5.0 x4 internal SSD TM8FFJ004T0C129

SKU CH-1XGK-79J8C MPN TM8FFJ004T0C129

A 4TB M.2 2280 internal SSD with PCIe 5.0 x4 interface, up to 10000 MBps read and 8500 MBps write, DRAM cache, and graphene heatsink

  • Total capacity4 TB
  • Sequential read speedUp to 10,000 MB/s
  • Sequential write speedUp to 8,500 MB/s
  • Interface typePCI-Express 5.0 x4
  • Form factorM.2 2280
  • Product typeInternal Solid State Drive (SSD)

Capacity 4TB

  • Up to 10000 MB/s sequential read for rapid game loading
  • Up to 8500 MB/s sequential write for fast large-file transfers
  • 2400 TBW endurance rating for long-term heavy workloads
  • Patented graphene heatsink maintains performance under sustained use
  • 1,600,000-hour MTBF indicates high reliability for critical data

Built for PCIe 5.0 x4 systems

This 4TB M.2 2280 internal SSD uses the PCIe 5.0 x4 interface and NVMe protocol to reach 10000 MBps sequential read and 8500 MBps sequential write. A graphene heatsink and the InnoGrit IG5666 controller manage thermals and power states. It is made for consumer workloads that need sustained throughput.

Suits high-throughput builds; not for legacy slots

The drive fits M.2 2280 slots wired for PCIe 5.0 x4 and operates from 0°C to 70°C. It offers 2400TB TBW and 1600000 hours MTBF for heavy write cycles. Systems limited to PCIe 3.0 or 4.0 will not use the full bandwidth, so buyers on older platforms should consider a matching-generation drive.

Deciding spec: 10000 MBps sequential read

That peak read speed only appears when the motherboard provides a PCIe 5.0 x4 link and NVMe 2.0 support. If the platform tops out at PCIe 4.0, the drive will still work but cannot hit the rated figure. Check the slot specification before purchase.

Questions about this item

What M.2 slot key and length does the 2280 form factor require?

The drive uses the M.2 2280 form factor, so it needs an M-key slot that accepts 80 mm long modules.

How do I install the TM8FFJ004T0C129, and which step is most often missed?

Insert the M.2 module into the motherboard M-key slot, then fasten the single retention screw; the step most often missed is securing that screw after seating the drive.

When will the 4 TB drive with 2400 TBW endurance need replacement?

The drive is rated for 2400 TBW and 1,600,000 hours MTBF; replace it once the SMART health indicator reports the endurance reserve is exhausted.
