Features
The LEGEND 900 PRO SSD features a DRAM-less design (HMB), similar to many other M.2 2280 SSDs currently available on the market. Under the heatsink, we find a Silicon Motion SM2268XT2 controller and rebranded 3D NAND, which appears to be the YMTC QLC series, based on SSD specifications and performance in our tests. The QLC NAND is cheaper, which affects the retail price, but it provides about half the endurance of the TLC. For the LEGEND 900 PRO 2TB, it’s 1200 TBW. On the other hand, recently tested QLC SSDs had 1000TBW for the same capacity. For most users, it doesn’t matter as writes are not so frequent in home and gaming workloads. The warranty of the SSD is limited to the specified TBW factor or five years, whichever comes first.
The LEGEND 900 PRO offers sequential bandwidth of up to 7.4 GB/s. This is at least what we can find in the specifications, as our test results say it’s slightly less. The performance is above that of most QLC and top TLC M.2 PCIe 4.0 SSD series, so it’s not the highest, but it still outperforms its direct competitors.
The SSD supports all the latest technologies to improve stability, data protection, and performance.
ADATA provides SSD ToolBox software that checks the SSD’s health and lets us update its firmware. The tested SSD arrived with the latest available firmware. There were no issues during all our tests.
Below is a screenshot from CrystalDiskInfo, one of the most widely used diagnostic programs. The SSD arrived in perfect condition with 0TB written.
Depending on the load, the drive’s temperature ranges between 35°C and 70°C. The maximum safe temperature for consumer-grade storage products is typically 85 °C, so it’s still far from our readings. Although the temperature increases significantly under load, we haven’t observed thermal throttling, making it a perfect SSD for laptops and PS5 consoles.
