SSD performance file copy tests

SSD Performance

In this benchmarks round, we start with our real-world file copy tests. Currently, specific controllers benefit from compressed files, yet others don't. Any storage unit's nightmare, whether an HDD or SSD, is storing tiny files as fast as possible. Specific storage units hate small files, whereas others work well with them. So, it only makes sense to do some manual tests on that.

File Copy

This is the most basic and simple test anyone can perform. We drop a ~ 200 GB avi file onto the SSD. The writing speed will fluctuate a bit here and there during the writing process. 

       The SSD managed to write the whole 200 GB, staying at about 2.3 GB/s.

Then it dropped to 2300 MB/s. The reason is the drive’s TLC NAND and an exhausted buffer. This should not be an issue for the average user. It might be a problem for those with hefty content creation workloads, but it’s still ~2300 MB/s, so is that an issue? It’s still quite fast (over four times faster that with SATA drives).

The audience that we cater to here at Guru3D.com is made up primarily of gamers. Therefore, I'd like to start offering real-world game performance tests. A lot of things happen in the system when a game is loading. The CPU is hard at work; your SSD loads up executables, binaries, shaders, textures, and whatnot, while the system memory processes it. With a fast SSD, you can decrease the overall loading time of your games and levels.

AS SSD Compression Benchmark

This test creates test patterns on the target drive, which are random and vary in the level of compression used in the test data. This ranges from 0% compressible to 100% compressible. Basically, for this chart, you want a straight line that’s as high as possible (no compression performance loss), which indicates the highest performance in MB/s.
