Albeit sluggish, we’re lastly seeing PCIe Gen5 SSD making its method to the buyer market. This time, we’ll be taking a fast have a look at the ADATA Legend 970 2TB PCIe Gen5 M.2 NVMe SSD, which is a somewhat distinctive strategy by ADATA I need to say. Whereas a lot of the PCIe Gen5 SSDs we’ve seen are largely geared up with a giant heatsink, the ADATA Legend 970 comes with a regular heatsink that has a tiny cooling fan hooked up.

Unboxing
The Legend 970 ships in a reasonably easy field, similar to the Legend 960 Max that we’ve beforehand examined however it’s labeled as 2000GB as a substitute of 2TB. The content material of the field is simply the Legend 970 with none extra equipment included and at first look, I can already see one thing that I’m not a fan of – the cooling fan on the heatsink requires SATA energy to run. In case you’re planning to make use of a Third-party heatsink for the Legend 970, disassembling and eradicating the warmth sink your self is taken into account man-made harm and won’t be lined by the guarantee. Not less than that’s what’s acknowledged on the official product web page.
As for the elements, ADATA determined to make use of the Phison PS5026-E26 PCIe 5.0 controller this time, paired with 232-layer 3D TLC NAND from Micron, and a 4GB DDR4-4266 from SK Hynix.
Benchmarks
For the benchmark, we’ve examined the Legend 970 utilizing the next specs to eradicate any potential bottleneck:
| CPU | Intel Core i9-13900K |
| Motherboard | ASUS ROG Maximus Z790 APEX |
| Reminiscence | ADATA XPG LANCER RGB DDR5@6000MHz CL30 (16GB x2) |
| Graphics Card | Gigabyte GeForce RTX 4060 Ti Gaming OC 16G |
| Energy Provide | Cooler Grasp M2000 Platinum |
| Major Storage | PNY LX2030 2TB SSD |
| CPU Cooler | Cooler MasterLiquid PL360 Flux |
| Chassis | Cooler Grasp MasterFrame 700 |
| Working System | Home windows 11 Professional 64-bit 21H2 (Construct 22000.1696); |
We’ve gathered the efficiency knowledge utilizing generally used instruments like CrystalDIskMark, ATTO Disk Benchmark, and AS SSD Benchmark for the bottom efficiency numbers as proven beneath:
From the information, we will see that the Legend 970 can certainly attain a powerful efficiency of as much as 10,000MB/s on each the sequential learn and write efficiency, barely higher than what’s listed on the official specs.
Relating to the linear write take a look at carried out with AIDA64, it’s evident that the SSD can obtain a write efficiency of as much as 9803MB/s. Nevertheless, a noticeable decline in efficiency turns into obvious across the 38-39% level of the take a look at, suggesting that the cache has reached its most capability. The cache clearing course of is noticed in subsequent exams till roughly the 47% mark, yielding a median efficiency of 3966.5MB/s for the SSD by the tip of the take a look at.
We then redo the take a look at with the SATA energy cable disconnected, and we will see the write efficiency declined quickly excellent after the 12% mark. The write efficiency then maintained at about 3600MB/s vary which was then adopted by a brief sharp drop earlier than going again as much as the 9800MB/s vary after which dropped below the 1000MB/s vary earlier than the take a look at ended. Clearly, that’s an indication of thermal throttle however simply how excessive did the temperature go earlier than the throttle kicks in?
From the temperature studying, the utmost load temperature of the SSD controller when the cooling fan is disabled is recorded at 85°C, which is the temperature the place the thermal throttle kicks in. The SSD write efficiency stays ‘regular’ when we have now the cooling fan working, retaining the temperature at round 69°C all through the take a look at. Whereas the cooling fan is unquestionably doing its job as meant, the fan is at all times working at full pace and there’s no method to management the pace, which is somewhat loud and I think about that as a draw back of this coolings answer.
Must you purchase the ADATA Legend 970?
Priced at $190 for the 1TB mannequin and $330 for the 2TB mannequin, the price of the ADATA Legend 970 locations it within the larger value vary, particularly when in comparison with equally high-speed PCIe Gen4 SSDs of the identical capacities. Whereas its efficiency is undeniably spectacular, it’s vital to notice that optimum outcomes can solely be achieved with {hardware} that helps PCIe Gen5 SSDs; in any other case, the SSD will function at PCIe Gen4 speeds. Moreover, it’s value mentioning that for typical players and common customers, some great benefits of PCIe Gen5 over Gen4 or Gen3 SSDs will not be but obvious for many utilization eventualities.
Nevertheless, people engaged in resource-intensive duties like content material creation, involving in depth rendering work and a requirement for speedy storage, would possibly discover worth on this SSD. Nonetheless, using the Legend 970 for such functions mandates a sturdy cooling answer attributable to its intensive workload. Whereas the cooling fan performs its operate successfully, potential considerations concerning fan noise and the need for exterior energy through a SATA cable must be critically thought-about earlier than committing to the acquisition of the Legend 970.
