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 110 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 we start at ~3.0 GB/sec sustained writes and that slowly drops to 2 GB/sec.

Copying the 100 GB file towards a client drive is good. Our 110 GB test file falls within the huge pSLC write cache of the 1TB SSD, ergo we do not run into TLC write holes.
