ADATA Spectrix S40G 512GB NVMe M.2 SSD review - SSD Performance File Copy Tests

SSD Performance

In this round of benchmarks, we start off with our real-world file copy tests. Currently, certain controllers benefit from compressed files, while others don't. Certain storage units hate small files, others work well with them. So it only makes sense to do some manual tests on that.

File Copy

The most basic and simple test anyone can perform. We drop a 100 GB compressed file onto the SSD. That write number will fluctuate a bit here and there during the writing process. Let's have a peek:

You can see as long as the buffer(s) can keep up, ~1.8 GB/sec sustained writes however at the measurement marker of roughly 25 GB of writes the TLC write hole kicked in a tiny bit but quickly recovered.

Copying the 100 GB file towards the 960 PRO is averaging out at  1.8 GB/sec and after 80Gb dropped a bit to 1.15 GB/s, that's the write hole on the Samsung. overall, the results are impressive for this test.
