OCZ Vertex 4 128GB review (firmware 1.5)

For years now, Vertex name is the one people talk about when talking about fast SSDs. OCZ has been on the forefront of SSD technology since the very beginning, and - so has Vertex as a "brand". Over the years, they've developed other very popular and talked-about products - for example, in desktop segment Agility, solid and others, in enterprise segment Revodrives. Let's see how the fourth generation of Vertex did on our test.

Before we begin, let's set the record straight - we're not gonna disciss older firmware revisions with slower seq read performance. We're only gonna discuss the latest version, wich is the v1.5. Make note that you should really update the drive from final version of 1.4 firmware, because then the firmware update isn't destructive (won't destroy your existing data on the drive). V1.5 firmware brings other improvements as well - better garbage collection, improved compatibility with various motherboards, and others. So, it's a very capable and needed update for this Indilinx Everest-based drive.

The garbage collection part actually deserves a bit of explanation as it's a very good feature that we find to be very useful. The general idea behind this was introduced in the v1.4 firmware, and the feature is called Performance Mode. What that means is - if your drive is 50% or less full, Vertex 4 is in Performance Mode, which means that you'll get better performance in sequential tasks. If you cross the 50% barrier, the drive automatically goes back to Standard mode, which means that Vertex 4 will reorganize data on the drive (which means performance degradation for a couple of minutes).
