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 tested with EVEREST Disk Benchmark are connected to the Intel SATA 6Gb/s controller and use a 1MB block size option. Read performance on the EDGE Boost Pro SSD measured an average 483.2 MBps bandwidth with a relatively close maximum peak speed of 501.8 MBps. Notice from the waveform below that the first 9% of capacity (approximately 10.06GB) produced very low performance results; this was seen in every single test we conducted regardless of NAND flash condition. Everest linear write-to tests were next...

The waveform chart below illustrates how the integrated buffer manages file transfers, and makes linear write performance appears relatively even. The results seen here are still relatively consistent compared to most other SSD products we've tested in the past. The EDGE Boost Pro solid state drive recorded an average linear write-to speed of 459.2 MBps, with a maximum performance of 481.3 MBps.

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...

I suspect the review wrong about this drive supporting the TCG OPAL specification.

Sandforce webpages claim it is an option, but I am not aware of any currently available Sandforce based SSD that actually supports it.

The drive webpage (##edgetechcorp.com/) makes no mention of TCG Opal.

ATA password != TCG Opal

Unfortunately after being burnt by a GTX460 review, a GTX460 that was supplied by the manufacturer for the review, and was a different spec to the released version I will take this one line very seriously:

Full Disclosure: The product sample used in this article has been provided by EDGE Tech.

But thanks for including it.

That is very unfortunate, which is why we disclose the source of our samples in every article. Almost every sample we receive is identical to full retail, but occasionally there are changes made to the retail product without any notice given.
