Review of 480GB version:
https://www.techradar.com/reviews...ternal-ssd

"When put to test, the performance of the SC680 was very similar to that of the SD600Q, that is average at best. We managed to move a 100GB file in 38 seconds, which translates into a real-life transfer rate of 263MBps. Another test, CrystalDiskMark, reached 426MBps on read and 391MBps on write speeds; Adata quotes up-to-speeds of 530/460MBps respectively.

The low performance can be attributed to the DRAM-less nature of the device as well as the use of QLC and tests carried out on other benchmark applications yielded similar results. "

"Opening the drive, ADATA has used a custom PCB with SMI2259XT and 3D NAND."
