SSD Performance File Copy tests

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 it. 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. So on our Test PC we created a RAMDISK partition (we can't use an SSD/HDD here as it would be a bottleneck) in which we install roughly 3GB worth files. We now measure how many seconds it takes to copy the files from the RAMDISK towards the storage unit tested today.

File Copy

The most basic and simple test anyone can perform. Above we simply drop a 38 GB compressed MKV file onto the SSD. As you can see the result starts at ~ 450 MB/sec writes, yet after a few secondss drops to 220 MB/sec. This is the culprit for TLC NAND. Read performance however is exellent.



Performance Game Load Times

Here at the audience is catered to gamers. And as such I like to start offer 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 increase the overall start time of your games. 


We now measure based on game sequence load and translate that into the number of MB/sec the storage unit can manage and load. Higher is better in this chart.

Performance ISO Creation

An ISO file is often comprised of many files archived into a file-container. For example creating a DVD. 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 Application Load Time

Here we emulate loading of complex software like Photoshop, Internet Explorer, Word, PowerPoint etc. So how many applications / dlls / hooks /etc simultaneously in MB/sec this storage unit can cope with?
