EVEREST Disk Benchmark

Many enthusiasts are familiar with the Lavalys EVEREST benchmark suite, but very few are aware of the Disk Benchmark tool available inside the program. The EVEREST Disk Benchmark 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. However, Hard Disk Drive products suffer a lower average bandwidth as the capacity draws linear read/write speed down into the inner-portion of the disk platter. EVEREST Disk Benchmark does not require a partition to be present for testing, so all of our benchmarks are completed prior to drive formatting.

Linear disk benchmarks are superior bandwidth speed tools in my opinion, because they scan from the first physical sector to the last. A side affect 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 table alignment will occasionally play a role in overall SSD performance (HDDs don't suffer this problem).

The high-performance storage products we've tested with Lavalys EVEREST Disk Benchmark are connected to the Intel P67-Express SATA 6Gb/s controller and use a 1MB block size option. Read performance on the MyDigitalSSD BP4 Slim 7-series solid state drive measured average speeds of 498.9 MB/s, with a relatively close maximum peak speed of 511.6 MB/s. These read speed results are among the fastest we've tested, and very consistent across the full range of capacity. Everest linear write-to tests were next...

The relatively straight waveform chart above illustrates how well the MyDigitalSSD BP4 Slim 7 solid state drive manages file transfers, and are consistent with most other SSD products we've tested in the past that use a DRAM cache buffer. The MyDigitalSSD BP4 Slim 7 solid state drive recorded an average linear write-to speed of 460.1 MB/s, with maximum performance reaching 467.0 MB/s. Write-to results fell behind many recently-tested SSDs, which could be explained by Vector's mission to deliver superior stability and NAND reliability opposed to raw performance figures.

The chart below shows the average linear read and write bandwidth speeds for a cross-section of storage devices tested with EVEREST:

Linear tests are an important tool for comparing bandwidth speed between storage products - although HDD products suffer performance degradation over the span of their areal storage capacity. Linear bandwidth certainly benefits the Solid State Drive, since there's very little fluctuation in transfer speed. This is because Hard Disk Drive products decline in performance as the spindle reaches the inner-most sectors on the magnetic platter, away from the fast outer edge.

In the next section we use PCMark Vantage to test real-world performance...

Performance isn't the best, but more than fine considering the price. I'd buy one just because it isn't a ubiquitous Sandforce. Thanks for the review.

No Samsung in the test???

Comparison? I remember past evaulations that oncluded Samsung drives that Outperformed Intel and gave the Vertex a run for the money

Samsung doesn't offer us samples for review, or they would be included. Regardless, all of the most popular SSD controllers are represented in our tests. Which Samsung SSD were you expecting to see?
