Recently, OCZ began simplifying its SSD product line quite significantly in order to make the decision-making process easier for consumers. This was also encouraged by the fact that even budget models today offer some great performance. OCZ’s Vertex 3.20 targets that market, replacing the Agility and Vertex 3. Is it a worthy successor?
Finally, we reach the first of our real-world tests where there are no unusual testing or scoring algorithms to leave us scratching our heads, just simple tests to see how an SSD changes actual system performance.
For the File Transfer test we took a 4.5GB compressed archive and measured how much time was required to transfer the file to another folder on the same drive. Keep in mind that with a hard disk, this requires the actuator arm to seek back and forth between the source and destination sectors on the disk platter, with the destination sectors often not sequentially aligned. In contrast, any SSD can concurrently perform read and write operations simultaneously on any NAND chip without regard to spatial considerations of bits strewn randomly around a disk platter, which gives them a large advantage here.
The 20nm NAND appears to be coming into play here, with the 3.20 posting results five seconds behind the V300.
Either you’ve heard of FLAC, or it is an integral part of your digital life. But iTunes and Apple devices do not support FLAC files, leaving those with discerning ears forced to use Apple’s Lossless codec. dBpoweramp makes it possible to convert between them utilizing as many threads as are available to the system.
In this test, we take 10 albums amounting to 4GB of FLAC files and convert them to Apple’s lossless format. This creates exactly 3.96GB of new data. This scenario is even more applicable for those users with six or more physical CPU cores available, because as the core count increases, the more the storage system will become the actual bottleneck. Our test rig is limited to only a quad-core processor, but even then we can see clear differences amongst the various contenders.
The sequential read and write performance of the new NAND again comes into play, with the 3.20 posting results just a few seconds behind the V300.
