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:

We see the SSD writing properly at ~ 470 MB/sec continuous until the SLC cache is depleted, this happens after roughly 80 GB of writes, then performance drops towards 162 MB/sec. So only after roughly 80GB of continued writes, the performance drops. 

Copying the 100 GB file from the SSD (read/copy) is averaging out 518 MB/sec. So that's nothing to be ashamed about really.
