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, ~2.1 GB/sec sustained writes. The test was a bit flakey though. We'll further examine this on the next page with another test.


Copying (read) the 100 GB file is averaging out at ~2.1 GB/sec, it does then drop but that was due to the target drive now capable of handling such load.
