OCZ TRION 150 - 240 GB SSD review - 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. Any storage unit's nightmare, whether that is an HDD or SSD, is storing really small files as fast as possible.

File Copy

The most basic and simple test anyone can perform. We simply drop a 38 GB compressed MKV file onto the SSD. As you can see, the result is almost 480 MB/s writes at the end of the file copy sequence for both SSDs. That number will fluctuate a bit here and there during the write process, but was pretty consistent. Yeah -- you can't complain here.

OCZ Trion - 480 GB 

Here you can immediately see the problem with a TLC NAND flash based unit, once the cache runs out, performance can drop significantly. To my estimation you will get a full blast 400~500MB/s for the first 3~4 GB of writes, then you will drop to 160~170 MB/s. Hey this is a value SSD, there is a compromise somewhere.

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 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 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. A high IOPS storage unit will score better here as it can manage more files in less time.
