Benchmarks: Atto Disk Benchmark
The Atto Disk Benchmark shows sequential performance when working with different size data. The Vertex 450 256GB starts off at 21MB/s when working with 1K data, which is roughly the same result we saw from the Vector 256GB at 24MB/s. From there in each step up the Vertex 450 256GB was between 5MB/s and 25MB/s slower than the Vector 256GB.
The OCZ Vertex 450 256GB closely matches the Vector's performance and ends up with a throughput of 501MB/s.
