EVEREST Disk Benchmark

EDITORS NOTE: Benchmark Reviews has also tested OCZ Vertex SSD RAID-0 Performance

EDITORS NOTE 05/10/2009: Benchmark Reviews has re-tested the OCZ Vertex with the latest v1.10 firmware, which includes TRIM support, and the resulting performance was generally identical to the previous firmware. Please remember that TRIM is a Windows 7 supported feature, and does not improve performance on Windows XP or Vista Operating Systesm.

Many enthusiasts are familiar with the EVEREST benchmark suite by Lavalys, but very few are aware of the Disk Benchmark tool available inside the program. The EVEREST Disk Benchmark (version 2.06.37) performs linear read and write bandwidth tests on each drive, and can be configured to use file chunk sizes up to 1MB (which speeds up testing and minimizes jitter in the waveform). Because of the full sector-by-sector nature of linear testing, Benchmark Reviews endorses this method for testing SSD products, as detailed in our Solid State Drive Benchmark Performance Testing article.

The SSD products tested with EVEREST Disk Benchmark are connected to the Intel ICH10R SATA controller resident on the Gigabyte GA-EX58-UD4P motherboard. Using the 1MB block size, our read performance measured an average 247.3 MBps and forms a near-perfect line as it scans across all sectors. At some point in the waveform, maximum read performance peaked at 249.7 MBps, indicating how well the Indilinx 'Barefoot' controller has improved over the previous designs by other manufacturers (like JMicron). Linear write-to tests were next...


Linear disk benchmarks are superior tools in my opinion, because they scan from the first physical sector to the last. A side effect of many linear write-performance test tools is that the data is erased as it writes to every sector on the drive. Normally this isn't an issue, but it has been shown that partition tables will occasionally play a role in overall performance. The large 64MB buffer helped our linear testing, as shown in the waveform chart below.

Although the chart makes the linear write performance appear unsteady, the results seen here are actually very good compared to other SSD products we've tested in the past. The OCZ Vertex easily outperforms the stated 160 MBps specification for write-to bandwidth, as our tests resulted in a 225.2 MBps average with a 242.7 MBps maximum peak write bandwidth.


The chart below shows the average linear read and write bandwidth for a cross-section of drives attached to the Intel ICH10 Southbridge. I personally consider this the single most important comparison of storage drive products, and although the Apex SSD is a bit crippled by the complex RAID-0 write-to performance, all of the others are spot-on.


Linear bandwidth certainly benefits the Solid State Drive, since there's very little fluctuation in transfer speed. Hard Disk Drive products decline in performance as the spindle reaches the inner-most sectors on the magnetic platter.

The heat section is unclear, you say SSD at load vs idle temps in one sentence but otherwise it seems you are comparing idle temps. The SSDs seem to cover the high and low end of the temperature spectrum so it is hard to understand where you get the conclusion that they are generally cooler.

# SSD Heat OutputOlin Coles 2010-10-05 09:32
Hello Greg: I've discontinued the measurement of heat output from SSDs. This is because each series of controller operates at a different temp, and the enclosure makes a difference as to how much heat is dissipated out through the walls. In general, SSDs emit a low level of heat, much less than any hard drive, but they do still produce heat.

# idle vs. full loadmike 2012-07-07 22:53
Could you please do just 1 more set of testing...

Even just 2 SSD vs 2 HDD's, Do an idle temp comparison vs a heavy usage test

Would be very interesting to see! Great article!

This is a couple years old but these HDD's were discontinued and OCZ will replace the defective units with Vertex Plus Revision 2. My speeds were hitting about 220MB/sec max and averaging 180MB/sec.

but one just like it. New but from e-bay. It died in less then a year.
