What are the speed specifications of the TeamGroup G70 Pro?

The maximum sequential read speed is 7400 MB/s, and write speed is 6600 MB/s. Performance varies by capacity, with optimal results on 2TB and 4TB models.

Is the G70 Pro suitable for laptops?

No, due to high power consumption (~8.25W) and heat output, the drive is not recommended for laptops. It’s better suited for desktops with passive cooling.

Which controller does the TeamGroup G70 Pro use?

The drive features the InnoGrit IG5236 controller — an eight-channel PCIe 4.0 solution competing with Phison E18 and Silicon Motion SM2264.

What warranty does the G70 Pro come with?

The manufacturer offers a five-year warranty with up to 1480TB write endurance for the 2TB model.

Quick answer

TeamGroup G70 Pro is an NVMe SSD featuring the InnoGrit IG5236 controller and 232-layer YMTC TLC NAND. It delivers speeds up to 7400/6600 MB/s but is unsuitable for laptops due to high power consumption.

TeamGroup has unveiled the new G70 Pro SSD, standing out among competitors with a blend of high performance and affordability. The drive supports PCIe 4.0 x4 and NVMe 1.4 protocol, delivering sequential read speeds up to 7400 MB/s and write speeds up to 6600 MB/s. It is powered by the InnoGrit IG5236 controller, which previously raised reliability concerns but appears to have addressed those issues in this model.

The G70 Pro is available in capacities ranging from 512GB to 8TB, though the 2TB and 4TB versions offer the best price-to-performance ratio. The drive utilizes 232-layer YMTC TLC NAND and includes an SK hynix DRAM cache, ensuring stable performance under heavy workloads. The 2TB model offers 1480TB of write endurance and a five-year warranty, meeting premium-segment standards.

However, the G70 Pro has drawbacks. High power consumption (~8.25W) and heat output make it unsuitable for laptops. The manufacturer offers versions with and without a heatsink, but passive cooling is recommended for stable operation. Additionally, component configurations may vary by batch, affecting predictable performance.

Compared to competitors like the Seagate FireCuda 530R, the G70 Pro lags in energy efficiency but excels in price for higher capacities. For users seeking a fast and reliable SSD for desktop PCs, this solution could be an excellent choice.
