TEAMGROUP T-FORCE G70 PRO Gen4 NVMe M.2 SSD Review

TEAMGROUP T-FORCE G70 PRO Gen4 NVMe M.2 SSD Review

Final Thoughts

The G70 PRO 1TB makes the most sense as a high-cache sequential workhorse and a PS5 expansion drive rather than a heavy mixed-IO production disk. The 2GB of Micron DDR4 cache, the 740 TBW endurance, the 5-year warranty, and the PS5-ready graphene heatsink round out a solid package. Whether it earns a stronger recommendation comes down to its street price against the Gen4 field, which is where the value case is won or lost.

Pros

Good burst speeds

Sizable cache update for this specific configuration

Heatsink options

Cons

Nothing until RAM crisis

Introduction

The PCIe Gen5 SSD wave has taken most of the spotlight over the past two years, but the Gen4 segment is still where its at with a lot of users not finding the need to go past the spec to Gen5. A good Gen4 drive at the right price covers gaming, content work, and general system duty without the thermal and pricing premium that Gen5 still carries. TEAMGROUP’s T-FORCE G70 PRO sits squarely in that space as the brand’s high-end Gen4 play, and the sample on our bench is the 1TB capacity in its graphene heatsink trim.

The G70 PRO first launched in June 2024, and with the current market climate by June 2026, two years into its production life, this already counts as one of the higher-end models in terms of price and performance. That time gap matters more than it might seem for a drive like this. The G70 PRO has shipped across its run with a rotating cast of NAND suppliers, so a sample pulled today is not guaranteed to carry the same flash as a launch-window review unit. We get into exactly what our sample is built from further in this review.

About the T-FORCE G70 PRO

The T-FORCE G70 PRO is the DRAM-equipped tier of TEAMGROUP’s G70 Gen4 family. Where the standard G70 runs on SLC caching alone, the PRO adds a dedicated DRAM cache to the InnoGrit controller, which is the configuration that separates a performance Gen4 drive from the value tier. It is offered from 512GB up to 4TB, with two cooling options across the range: a patented ultra-thin graphene heat-sink and an aluminum alloy heat spreader, both designed to clear the PlayStation 5 expansion slot height requirement.

Our review sample is the graphene heatsink version, which is the thinner of the two options and the one better suited to laptops, Mini PCs, and the PS5 slot where vertical clearance is tight. The aluminum heat spreader version targets desktop builds without integrated M.2 cooling.

Features & Specifications

• InnoGrit IG5236 (Rainier) Gen4 controller with full DRAM cache support
• 2GB DDR4-3200 DRAM cache on our 1TB sample (2x Micron MT40A512M16LY, one per side)
• Micron B47R 176-layer 3D TLC NAND with dynamic SLC caching (this sample)
• PCIe 4.0 x4 NVMe M.2 2280 form factor
• Rated up to 7,400 MB/s sequential read / 5,500 MB/s sequential write (1TB capacity)
• Up to 1,000K random IOPS on the IG5236 controller platform
• Graphene heat-sink on our sample (aluminum heat spreader optional)
• 740 TBW endurance on the 1TB capacity

Closer Look – TEAMGROUP T-FORCE G70 PRO 1TB

TEAMGROUP ships the G70 PRO in the standard T-FORCE retail packaging, with the drive and its heat dissipation module inside.

Our sample is the graphene version, which keeps the overall profile thin enough for restricted-clearance installs. The front label carries the model number, capacity, serial, and regulatory markings, with the warranty-void seal noted on the label itself.

Drive PCB and Components

With consumers more aware than ever that part revisions can shift performance over a product’s life, we document the key components on the sample as received. The G70 PRO launched in June 2024 and has rotated through several NAND suppliers since, so the configuration below reflects this specific June 2026 unit rather than the product as a whole. Our sample is a dual-sided board carrying four NAND packages and two DRAM dies, one per side, which is the full-population layout used on the higher-capacity G70 PRO boards.

• Controller: InnoGrit IG5236, IG5236CAA revision. Launch-window units carried the IG5236FAA stepping. The eight-channel controller addresses sixteen dies on our sample, two CE per channel, with the NAND interface running at 1200 MT/s.
• NAND: Micron B47R 176-layer 3D TLC, confirmed by flash ID readout (manufacturer ID 0x2C, 512Gb per die). Four packages marked S29F2T08EMLEE with a 2509 date code (early 2025 production) populate the board, each carrying 2Tbit (256GB) across four 512Gb dies, for sixteen dies and 1TB total. The S29F2T08EMLEE marking is a TEAMGROUP house relabel that hides the die vendor on the topside, but the controller-level flash ID leaves no doubt it is Micron underneath. The G70 PRO has shipped YMTC 128-layer and SK Hynix V7 across its production run; this June 2026 sample is the Micron B47R configuration.
• DRAM: 2GB DDR4-3200 cache, made up of two Micron MT40A512M16LY-062E:D dies (FBGA code D9WFJ), one on each side of the PCB. Each die is an 8Gbit (1GB) DDR4 component, putting this 1TB sample at a generous 2GB of DRAM cache. With both NAND and DRAM sourced from Micron, this sample runs an all-Micron memory subsystem.

Heatsink and Thermal Design

The graphene heat-sink on our sample is the thin-profile option, a graphene layer bonded to the drive rather than a finned metal block. It adds minimal height, which is what makes this version the right pick for laptops, Mini PCs, and the PlayStation 5 expansion slot.

For a desktop build with no integrated M.2 cooling, the InnoGrit IG5236 runs warm enough that the motherboard heatsink or the aluminum heat spreader variant is the better call, but for clearance-limited installs, the graphene version does its job.

Linear Performance Testing

SSD performance ratings, particularly on the write side, are usually only achieved in optimal conditions, short bursts of sequential transfers within the drive’s SLC cache window. To characterize how the drive actually behaves under sustained load, we run a script that writes 1GB data files continuously until the drive is filled or until we hit the saturation point where post-cache write speeds settle.

CrystalDiskMark Performance

CrystalDiskMark is the most actively updated disk benchmark among the tools we use and the most dependable of the bunch. Results are not comparable version to version, which limits how far we can extrapolate against older entries in our archive, but as a direct, repeatable benchmark, it does the job. It gives us control over the test data pattern, the test data size, the number of passes, and individual benchmark selection.

PCMark 10 Storage Benchmark

PCMark 10 runs a set of storage benchmarks built on real-world traces pulled from popular applications and common tasks, giving us a practical read on how a modern drive behaves under everyday workloads rather than synthetic peaks alone.

The G70 PRO scored 2,630 points and 415.75 MB/s in the Full System Drive test with 63 microsecond access times, and 3,070 points and 368.53 MB/s in the Quick System test at 41 microseconds. The Full System bandwidth sits below the Gen4 average in our set, in line with the 3DMark result and again pointing to the older NAND as the limiter under mixed real-world IO.

3DMark Storage Benchmark

The 3DMark Storage Benchmark uses traces recorded from popular games and gaming-related activities to gauge real-world gaming storage performance, covering tasks such as:

• Loading Battlefield V from launch to the main menu
• Loading Call of Duty: Black Ops 4 from launch to the main menu
• Loading Overwatch from launch to the main menu
• Recording a 1080p 60 FPS gameplay video with OBS while playing Overwatch
• Installing The Outer Worlds from the Epic Games Launcher
• Saving game progress in The Outer Worlds
• Copying the Counter-Strike: Global Offensive Steam folder from an external SSD to the system drive

The G70 PRO posted 2,058 points and 355.71 MB/s here, which places it at the lower end of the Gen4 field in our database. This trace leans on mixed and random IO drawn from real game activity rather than long sequential runs, and it is the test where the drive trails newer-NAND competitors most clearly.

Final Fantasy XIV Dawntrail Storage Benchmark

Final Fantasy XIV ships a standalone benchmark application for PC. A long-standing feature of it is the loading-time capture, a summary of the load times between each scene across the benchmark run. We take the aggregate of those scene loading times for the storage score.

The G70 PRO completed the Dawntrail loading run in 6.13 seconds, one of the quicker times in our database and ahead of most of the Gen4 field along with several Gen5 drives. Scene loading leans on burst sequential reads, which is exactly where this drive is strong, and the result lines up with that.

PlayStation 5 Transfer Test

The PlayStation 5 supports storage expansion through M.2 drives, and most SSD makers now advertise PS5 compatibility, so we fold PS5 bandwidth testing into our reviews. We use the console’s internal read-speed test for initialization. Because of how Sony built that test, we average at least five reads with the drive freshly formatted after a rest period for the cleanest thermal results.

Our sample returned a PS5 internal benchmark of 6,472 MB/s, clearing Sony’s 5,500 MB/s expansion requirement with headroom and landing in the upper bracket of our database. Moving an 84.10GB game install as the real-file payload, the drive measured 2,169.76 MB/s read and 245.61 MB/s write. The read figure is among the quickest we have logged, while the write sits mid-pack with the rest of the field, which clusters tightly in the 230 to 253 MB/s range against the console’s own ingest ceiling.

Conclusion

The TEAMGROUP T-FORCE G70 PRO is a drive of two halves: On the sequential and cache side, it delivers exactly what the spec sheet promises. CrystalDiskMark cleared the rated 7,400 MB/s read and landed on the 5,500 MB/s write target, and the sustained write run revealed one of the largest SLC caches we have measured on a 1TB drive at roughly 324.8 GB, holding a peak average near 3,980 MB/s before settling. For bulk file moves and game installs, this is a fast and roomy drive.

The real-world and gaming-trace tests tell a more measured story. In 3DMark’s Storage Benchmark the G70 PRO posted 2,058 points and 355.71 MB/s, which places it at the lower end of the Gen4 field in our database, and PCMark 10’s Full System trace returned 415.75 MB/s, below the Gen4 average. These traces lean on mixed and random IO rather than long sequential runs, and the older Micron B47R 176-layer NAND on our sample is the most likely reason the drive trails newer-NAND competitors here.

Where it counts for its target buyer, the picture is friendlier. The PS5 internal benchmark hit 6,472 MB/s, well past Sony’s 5,500 MB/s bar, and Final Fantasy XIV Dawntrail loaded in 6.13 seconds, one of the quicker times we have recorded and ahead of most Gen4 drives and several Gen5 ones. Games that load in bursts and console expansion duty both play to this drive’s strengths.

The G70 PRO 1TB makes the most sense as a high-cache sequential workhorse and a PS5 expansion drive rather than a heavy mixed-IO production disk. The 2GB of Micron DDR4 cache, the 740 TBW endurance, the 5-year warranty, and the PS5-ready graphene heatsink round out a solid package. Whether it earns a stronger recommendation comes down to its street price against the Gen4 field, which is where the value case is won or lost.

By 2026, the price for the T-FORCE G70 PRO is highly volatile with Q2 2026 ranging from $200-300. Barring pricing, the performance is already as stated. As always, weigh your options well in these times.

TEAMGROUP backs the T-FORCE G70 PRO with a 5-year limited warranty service. I recommend it if it’s your only option, and I’m not bullish about that changing for the rest of 2026.
