SSD Performance File Copy Tests
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. Any storage unit's nightmare, whether that is an HDD or SSD, is storing really small files as fast as possible.
The most basic and simple test anyone can perform. We drop a 110 GB compressed MKV 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 cache buffer(s) can keep up, ~2.0 GB/sec sustained writes (which is impressive). BTW we use a Samsung 970 EVO Plus to be able to counter write performance.
Once the buffer(s) runs dry, the write perf drops to merely ~900 GB/sec. This happens after ~70% of the writes meaning a buffer of give or take 75 GB before the TLC based SSD runs out of writing stamina. That's plenty really, as to how often do you write more than 75 GB at once? However, the performance after that is hit hard relatively speaking.
Copying the 110 GB file towards the EVO is averaging out at a similar 2 GB/sec. Funny story, I copied this 110GB file from a Gigabit NAS towards the test SSDs, that took me 18 minutes. Copying the file over the SSDs ... gone in 60 seconds.
Performance ISO Creation
An ISO file is often comprised of many files archived into a file-container, for example creating a DVD or Bluray. Below, that situation is emulated. A fast writing SSD will be able to create an ISO much faster opposed to a slower writing SSD. In the chart below faster is better.
Performance Game Load Times
Here at Guru3D.com, the audience catered to is primarily made up of gamers. And as such, I'd like to start offering real-world performance game tests. During game load, a lot of things happen in the system. The CPU is hard at work, your SSD loads up executables, binaries, shaders, textures and what not while the system memory process it all. Thing is, with a fast SSD you can really decrease the overall load time of your games and levels.
We now measure based on game sequence load and translate that into the number of MB/s the storage unit can manage and load. Higher is better in this chart.
Performance Application Load Time
Here we emulate the loading of complex software like Photoshop, Internet Explorer, Word, PowerPoint etc. So how many applications / dlls / hooks / etc. simultaneously in MB/s this storage unit can cope with. High IOPS storage units will score better here as it can manage more files in less time.
