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)
4 KB Random Writes (IOPS)
128 KB Sequential Reads (MB/s)
Now: 550
Previously: 535
Now: 550
Previously: 535
Now: 550
128 KB Sequential Writes (MB/s)
Now: 420
Previously: 200
Now: 465

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.

    Now that's an update!

    hell yea... wish there were more out there like it. If only my AMD 7970 card could be made 210% faster with a driver patch, lol

    The title definitely skews the facts presented. A definite improvement is noticed, but only on one spec and one of the models - not the entire Vertex 4 lineup as the title would have you think. Still, I'll take the 2.8% and 22% performance from the other drive with the updated speeds. Anything is better than nothing, just hoping reliability remains in check.

    Edit: In addition to the fuzzy number wording, this is also not the first Vertex without a Sandforce controller - correct me if I am wrong.......
