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, ~1.3 GB/sec sustained writes. 

Copying the 100 GB file towards the SSD (write) however quickly runs into an issue. After writing a few GB the SSD will quickly hit the TLC write hole, and this SSD has no DRAM buffer to deal with that. Once it kicks in you're looking at SATA3 SSD performance on writes, so yeah that's not really impressive.
