"The Vertex 4 was able surpass other SSDs when looking at its ramped 4K write speeds" - Storage Review
Hello Everyone,
Storage Review has completed thier review of the Vertex 4 and highlighted the new drives performance and exceptionally low latency.
In the review they state:
"With strong I/O performance off the line, the OCZ Vertex 4 showed its strength leading the pack by a wide margin. The 256GB and 512GB Vertex 4 had an average latency of 0.096ms and 0.102ms, with a measured queue depth of 4 in this specific test. This compared to the Intel SSD 520 which measured 0.146ms or the Vertex 3 MAX IOPS that average 0.189ms to complete the same task."
"When we first broke the news of OCZ switching to Everest 2 for the flagship Vertex 4 SSD, we knew it would be both a bold move and one that's required for the long term viability of the company, as only those who can differentiate their SSDs with unique technologies will be able to significantly grow market share. By leveraging their own controller technologies, OCZ can not only tweak the controller and firmware exactly as they please, but they can also more quickly respond to support needs as they arise, eliminating bottlenecks that can occur otherwise."
"The main strengths of the OCZ Vertex 4 and the Indilinx Everest 2 controller are its incompressible write speeds and industry-leading low-queue depth random I/O speeds. The Vertex 4 was able surpass other SSDs when looking at its ramped 4K write speeds, hitting its peek speed of 82,000 IOPS for the 512GB model at a queue depth of four, while others needed a queue depth of 16 or greater to reach their maximum performance. In our new fixed I/O latency tests we also saw substantially lower average latency times from the Vertex 4 hitting a target of 40,000 IOPS with response times measuring 0.096ms."
"The Vertex 4 highlights OCZ's commitment to building a deep IP portfolio to further enhance their SSD offerings. As a whole, we found the Vertex 4 to be a reliable performer, distinguishing itself in random 4K performance. Additionally, the Vertex 4 doesn't drop in performance with incompressible data and was even throughout steady state testing."
