# Team Group T-Force GE Pro 4 TB pairs Innogrit with YMTC NAND (2026)

The Team Group T-Force GE Pro 4 TB pairs Innogrit's IG5666 controller with YMTC 232-layer TLC to deliver mid-tier PCIe 5.0 performance at 14,000 MB/s reads.

Quick answer: Buy the Team Group T-Force GE Pro 4 TB if the host motherboard already has a PCIe 5.0 M.2 slot and the goal is large-capacity Gen5 storage from the IG5666 plus YMTC platform. Skip it when the host platform tops out at PCIe 4.0, because the Gen5 bandwidth goes unused there, or when peak random 4K performance matters more than sequential headroom. The WD Black SN850X 4 TB is the safer call for a pure gaming rig on a Gen4 board, and the Crucial T705 is the pick for buyers who want maximum Gen5 speed regardless of cost. Our take: the GE Pro 4 TB is a sensible mid-tier Gen5 choice that delivers the bandwidth on paper and enough sustained headroom to justify its place, as long as the rest of the system can actually use it.

## Performance

The Team Group T-Force GE Pro 4 TB is rated for 14,000 MB/s sequential reads and 11,800 MB/s sequential writes over its PCIe 5.0 x4 interface. Those are paper maxima that show up in CrystalDiskMark's short burst runs, where the SLC cache is wide open and the queue depth is stacked in the drive's favor. In real workloads the gap to a good PCIe 4.0 drive narrows considerably: game load times, application launches, and everyday desktop responsiveness feel largely identical, because those tasks are bounded by queue depth and read latency, not raw peak bandwidth.

Where the 4 TB does flex is in sustained throughput. With 4 TB of TLC and a DRAM buffer, the SLC cache holds a large fraction of the drive, so multi-hundred-gigabyte file transfers, video scratch disk work, and DirectStorage-enabled titles that stream large asset archives benefit most. Once the cache exhausts, writes settle to the native TLC write speed of the YMTC 232-layer NAND, which is meaningfully lower than the burst figure. Team Group does not publish random IOPS figures for the GE Pro, so no reliable 4K random number can be cited.

Independent reviewers find the IG5666 plus YMTC 232-layer combination competitive with other mid-tier Gen5 drives in synthetic bandwidth while trailing the Phison E26 flagships in random 4K and sustained steady-state writes. For gaming and mixed-use workloads that delta is hard to feel. The honest takeaway is that 14,000 MB/s reads only matter for workflows that actually move enough data to saturate a PCIe 5.0 x4 link.

## Endurance, TBW & Warranty

Endurance on the Team Group T-Force GE Pro 4 TB is rated at 2400 TBW, twice the 1200 TBW of the 2 TB and four times the 600 TBW of the 1 TB. The drive is backed by a 5-year limited warranty that ends at whichever of the two limits, time or terabytes written, arrives first. At a typical 20 GB of writes per day, 2400 TBW works out to roughly 120,000 days, or about 329 years of continuous use, which means the warranty will expire on the calendar long before the NAND does. Even doubling or tripling that daily write load leaves decades of headroom. Team Group does not publish an MTBF for the GE Pro, but drives on the Innogrit IG5666 platform generally sit around 1.6 million hours. Treat that as a population statistic for expected reliability across many units, not a guarantee that any individual sample will run for nearly two centuries.

## Verdict

Buy the Team Group T-Force GE Pro 4 TB if the host motherboard already has a PCIe 5.0 M.2 slot and the goal is large-capacity Gen5 storage from the IG5666 plus YMTC platform. Skip it when the host platform tops out at PCIe 4.0, because the Gen5 bandwidth goes unused there, or when peak random 4K performance matters more than sequential headroom. The WD Black SN850X 4 TB is the safer call for a pure gaming rig on a Gen4 board, and the Crucial T705 is the pick for buyers who want maximum Gen5 speed regardless of cost. Our take: the GE Pro 4 TB is a sensible mid-tier Gen5 choice that delivers the bandwidth on paper and enough sustained headroom to justify its place, as long as the rest of the system can actually use it.

## Frequently Asked Questions

### Is the Team Group T-Force GE Pro 4 TB good for gaming?

The Team Group T-Force GE Pro 4 TB is more storage than a gaming rig strictly needs, but it is a capable pick for a Gen5 build. The 14,000 MB/s read rating only shows up in synthetic bandwidth tests, since most current games are bounded by read latency and queue depth rather than peak sequential speed, so load times feel similar to a good PCIe 4.0 drive. The real gaming upside is DirectStorage titles that stream large asset archives from the SLC cache, where the 4 TB capacity and DRAM buffer keep throughput high. If the rest of the system is PCIe 4.0, the Gen5 bandwidth is wasted and a cheaper Gen4 drive makes more sense.

### Does the Team Group T-Force GE Pro 4 TB work in a PS5?

The Team Group T-Force GE Pro 4 TB does work in a PS5, but it is a wasteful match for the console. Sony's requirements are an M.2 NVMe SSD with at least 5,500 MB/s sequential read, fitting within 110 by 25 by 11.25 mm including a heatsink, and the GE Pro clears the size and speed bars. The catch is that the PS5's expansion slot is PCIe 4.0, so the drive runs at roughly half its rated Gen5 speed and the remaining bandwidth goes unused. A PCIe 4.0 drive like the WD Black SN850X delivers effectively identical PS5 performance without the wasted Gen5 headroom.

### Does the Team Group T-Force GE Pro 4 TB have a DRAM cache?

Yes, the Team Group T-Force GE Pro 4 TB has a discrete DRAM buffer alongside the Innogrit IG5666 controller and YMTC 232-layer TLC NAND. The DRAM cache holds the flash translation layer mapping table, which speeds up random accesses and sustained writes compared with DRAM-less designs that lean on HMB. On a 4 TB drive the DRAM buffer matters more than on smaller capacities, because the mapping table scales with flash size, and it is one reason the GE Pro holds up better under heavy write loads than budget Gen5 drives that skip the DRAM. Team Group does not publish the exact DRAM capacity.

### What is the TBW endurance of the Team Group T-Force GE Pro 4 TB?

The Team Group T-Force GE Pro 4 TB is rated at 2400 TBW, the highest endurance in the GE Pro line and twice the 1200 TBW of the 2 TB model. That works out to a consistent 600 TBW per terabyte across the family. At a typical 20 GB of writes per day, 2400 TBW translates to roughly 329 years before the NAND is exhausted, so for any realistic consumer or creator workload the 5-year warranty will expire on the calendar long before the drive wears out. The warranty is limited to whichever of five years or 2400 TBW comes first.

### Does the Team Group T-Force GE Pro 4 TB need a heatsink?

Yes, the Team Group T-Force GE Pro 4 TB needs a heatsink, and one is not included in the box. PCIe 5.0 drives run significantly hotter than PCIe 4.0 models, and the Innogrit IG5666 controller under load can hit thermal throttle points without active cooling. Most motherboards with a Gen5 M.2 slot ship with a bundled M.2 heatsink that will work, but buyers relying on a bare slot will need to add an aftermarket heatsink. Running the drive without cooling risks sustained throttling that would erase the Gen5 bandwidth advantage that justifies buying it in the first place.

### How does the Team Group T-Force GE Pro 4 TB compare with the Crucial T705?

The Team Group T-Force GE Pro 4 TB sits below the Crucial T705 on peak performance, since the T705 uses Phison's flagship E26 controller and hits higher random 4K and sustained write numbers. The GE Pro's 14,000 MB/s read and 11,800 MB/s write ratings are competitive in synthetic bandwidth, but the IG5666 plus YMTC 232-layer platform is positioned as mid-tier PCIe 5.0 rather than flagship. For buyers who want the absolute fastest Gen5 drive and will tolerate the flagship cost, the T705 is the stronger pick. For buyers who want Gen5 bandwidth and can accept slightly lower random performance, the GE Pro 4 TB is the more sensible match.

### Is the Team Group T-Force GE Pro 4 TB good for video editing?

The Team Group T-Force GE Pro 4 TB is a solid scratch disk for video editing, where large file sizes and sustained reads matter more than random 4K performance. The 4 TB capacity fits multiple large project bins and render caches, the DRAM buffer keeps multi-gigabyte clip previews responsive, and the PCIe 5.0 bandwidth shows up when shuttling footage between drives. The caveat is sustained writes: once the SLC cache fills during a long render export, throughput drops to the native TLC write speed, which is lower than the burst figure. For 4K and 8K NLE workflows the GE Pro is capable, but not a replacement for a proper NVMe RAID.
