EVEREST Disk Benchmark
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 linear read performance tests measured an average 167.7 MBps and forms a near-perfect line as it scans across all sectors. At some point in the waveform, maximum read performance peaked at 167.8 MBps, indicating how well the dual JMicron controllers can handle a sustained linear workload. 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 custom BIOS in the G.Skill Titan seemed to have helped performance in 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. When we tested the OCZ Apex SSD with EVEREST, the write-to tests were horribly limited and showed extremely degraded performance. Oddly enough, the G.Skill Titan had not problems at all despite the identical construction and engineering. All that separates the two products is the firmware, which is custom tailored by each company.
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 results for the OCZ Apex appear bit crippled (because of firmware incompatibilities with EVEREST), 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.
In the next section, Benchmark Reviews tests the buffered transaction performance for the G.Skill Titan SSD using HD-Tach, and compare the results to dozens of other products.
