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 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 Comay Venus Pro 3 solid state drive measured average speeds of 490.8 MB/s, with a relatively close maximum peak speed of 500.0 MB/s. Everest linear write-to tests are next...

The waveform chart below illustrates how well the Comay Venus Pro 3 manages file transfers, and makes linear write performance appears relatively uneven. The results seen here are consistent with most other SSD products we've tested in the past that use an integrated cache buffer (generally all SandForce products). The Comay Venus Pro 3 solid state drive recorded an average linear write-to speed of 471.8 MB/s, with maximum performance reaching 483.6 MB/s.

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...

Pretty amazing. How long did it take for storage devices to catch up to the SATA 3 standard? Now after only a couple of years, storage devices are already near saturation for SATA6. LOL totally amazing. This thing can transfer 30GB/minute.

It will still be a wait for USB 3 devices to catch up to the USB 3.0 saturation rate so we can see the benefit of USB3 to something as fast as this device. I can't wait to see CF flash or something similar come into line with the USB3 theoretical. Most cards never got past a little over half of the USB2 specs.

Olin,

You say this drive is expensive, but I didn't see a price in the review.

I don't think now is a good time to be entering any 'expensive' SSD into the market.

Yesterday I saw a sub 140 240GB Vertex3 in the wild. I paid more than that (170) for my 128GB Samsung 830 only 6 months ago.
