SSD Performance Real World 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:

Here we are copying from (read) towards the destination drive. You can see the SSD keeps up, ~2 GB/sec sustained writes. 

Copying the 100 GB file towards the SSD (write) is averaging out 1.7 GB/sec. So yeah, that's nothing to be ashamed about really. We did not notice the dreaded QLC/TLC write hole here. Good stuff.
