OWC Mercury Extreme Pro-RE Conclusion

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.

The high-performance storage products tested with EVEREST Disk Benchmark are connected to the Intel ICH10 controller on the Gigabyte GA-X58A-UD7 motherboard. Using the 1MB block size, read performance of the 100GB Mercury Extreme Pro-RE Solid State Drive measured an average 256.3 MBps with a similar maximum peak of 259.8 MBps. 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 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 waveform chart below illustrates how the integrated buffer manages file transfers, and makes linear write performance appear even yet unsteady. The results seen here are still relatively consistent compared to most other SSD products we've tested in the past. The OWC Mercury Extreme Pro-RE SSD recorded an average linear write-to speed of 251.2 MBps, with a maximum performance of 253.2 MBps.

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

I personally consider linear tests to be the single most important comparison of storage drive products, although HDD products suffer performance degradation over the span of their 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.

Drive Hardware

In the next section, I share my final thoughts on the struggle between SSD and HDD technology before delivering my conclusion and final product rating.

It's true that OWC has supported the Mac for many years; and it's also true that the very latest Snow Leopard operating system does not support TRIM. This is especially annoying when you consider that Apple was one of the first (if not the first) company to ship an SSD in their computer-- the original MacBook Air.

not sure how you can say its one of the most affordable when clearly it is not.
the agility 2, Vertex 2 and, i might be wrong, but the corsair are all cheaper.

the mistake here being that it is sold on a MAC website, which, instantly means you will pay more for it, because it is pushed as a MAC product.

she's fast, or dear is she fast, but its not the cheaper of the SF-1200 controllers.

You are comparing to lower end drives. If you want a price comparison, you should compare to the Vertex 2 pro which is closer is specs, etc... If you compare to drives meeting similar specs you will find this is fairly attractive for entry level enterprise. The drives are you are comparing to will not last for high-abuse data server systems. Drop the RE from the product and you will get a lower cost model that closer compares.

I?m exceedingly satisfied with my 60GB OWC Mercury Extreme Pro SSD drive. It replaced my 250GB MacBook HHD.

Boot up time is more then twice as fast as before. Prior boot up average 52.6 seconds. Boot up average now 22.1 seconds. Applications even faster !


AS of 7/05/10 23.79gb Used 35.89gb Free Total 59.68gb.

I second that -- just installed the 60GB OWC Mercury Pro Extreme SSD in my Mac Mini 3,1 (late 2009), and am impressed with the overall improvement in real-world performance.

Boot time reduced by about 40 to 50%.
At start up, the 7 or 8 apps I have set to auto-launch ALL open together within one or two bounces. I never used auto-launch at login before because it used to be so slow.
Even apps like OpenOffice 3.2 and Filemaker Pro 11 launch within 1 or 2 dock bounces. Mail launches and is usable within .5 second of clicking on it. Paging through large PDFs in preview is smooth and almost seamless, as is Coverflow or iPhoto preview of large groups of photos or PDFs.

Best upgrade I've made to any computer I can ever recall owning; been using them since the Timex Sinclair 1000 in 1980.

through the years, What I know memory ram and cpu are the most important to open fast and load the windows...now i know it's the SSD !! Geez hw many years wasting time for memory and cpu ideology!
