New OCZ Firmware Boosts Vertex 4 Performance Up to 210%
OCZ just released a new firmware (v1.4RC) this morning that boosts the performance of its Vertex 4 SSD (check out: OCZ Vertex 4 Review: A Flagship SSD Powered By...Indilinx?). Random read and write performance hasn't changed, but OCZ has made a few tweaks to sequential read and write speeds that should provide a major performance benefit. Across the entire Vertex 4 product line the data rate for sequential reads now top out at 550 MB/s, a meager 15 MB/s improvement.
|Vertex 4 Performance Specifications||128 GB||256 GB||512 GB|
|4 KB Random Reads (IOPS)||90,000||90,000||90,000|
|4 KB Random Writes (IOPS)||85,000||85,000||85,000|
|128 KB Sequential Reads (MB/s)||Now: 550|
|128 KB Sequential Writes (MB/s)||Now: 420|
With the exception of the 512 GB capacity point, sequential writes see a major improvement. If you own the 128 GB model, you'll see a 210 percent increase in performance, as the data rate is now 420 MB/s. At 256 GB, the firmware tweaks made by OCZ only yield a 22 percent gain - from 380 MB/s to 465 MB/s. The great thing is that these speeds obviously apply to incompressible data, an important distinction considering this is OCZ's first performance Vertex drive that doesn't feature SandForce.
