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 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 ICH10R SATA controller resident on the Gigabyte GA-EX58-UD4P motherboard. Using the 1MB block size, read performance of the Western Digital VelociRaptor 300GB WD3000HLFS 10,000 RPM SATA Hard Disk Drive measured an average 103.2 MBps with a maximum peak of 124.1 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 tables will occasionally play a role in overall SSD performance (HDDs are more mature products and don't suffer this problem). The 16MB buffer on the WD VelociRaptor helped improve results in our linear testing, as shown in the waveform chart below.

Although the chart makes the linear write performance appear unsteady in a few areas, the results seen here are actually very good compared to most other HDD products we've tested in the past. The WD VelociRaptor recorded an average linear write-to speed of 102.4 MBps , with a maximum performance of 124.2 MBps. Unlike SSDs, hard disk products generally share very similar read/write bandwidth performance.

The chart below shows the average linear read and write bandwidth for a cross-section of other SATA drives attached to the Intel ICH10 Southbridge:

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. I personally consider linear tests to be the single most important comparison of storage drive products, although hard disk drive products decrease performance as they reach the edge of the spindle, SSD products operate at a relatively smooth speed from start to finish.

speed is good i am happy with it but the storage capacity is not as i expected

you bought a 300gb but expected a 1tb eh?

This review said it all, it's the best HD on the market right now and its price still beats SSD's - but not for long, I'd expect that by the end of 2010 they will be very nearly neck and neck

Not Satisfied. Strange comment by Prasanth: 300GB gives you 300GB! Surely you did not expect more storage capacity? I have found the drive to be very impressive "in normal use" and a very acceptable alternative to the (presently) too-expensive top of the range SSDs. Josh is spot on!

ssd's beat raptors for price vs performance a long time ago lulz.

This drive should be great but it dies
I installed six of this drive on three servers with two mirrored on each. After one month one of then died. And after six months another one died. Good thing I had them mirrored.
I got the first one replaced and will have to replace the other one.
So be prepared.

# Re VelociRaptor and SSD'sforwards 2011-10-26 13:38
Well here we are at the end of 2011 and still waiting for that SSD price fall and still paying in excess of the $2.00/GB here in Australia. Also newest SSD failed after four days with bad sectors. Wonder if S.M.A.R.T.Reporter is actually the right tool to monitor SSD's.

I have a WD3000HLFS (bought end of 2008, or 2009, don't remember), and I statisfied. No any problems, the speed is enough, the capacity sufficient for the all day usage.

VIVA WD VelociRaptor :-)

hi there wii has 512 mb ssd wii u 8.5 gb ssd xbox 360 slime 4 gb ssd ps3 ultra slime 16 gb ssd xbox 720 will be using the 10,000 rpm veloci-raptor 2.5 inch 250 gb hard drive playing halo at 10,000 rpms will be alwsoume if microsoft next gen console woth next gen hard drive then 20,000 rpm veloci-raptor then a laser velociraptor at 50,000 times 20,000 rpms thats 10,000,000 rpms hard drive then a hybride 20,000 rpm hdd/ssd/laser hdd 20,000 rpm hard drive solid state with laser too the veleci-raprtors petabytes per second read write speeds
