Drive Testing Methodology

Comparing a Solid State Disk to a standard Hard Disk Drives is always relative; even when you're comparing the fastest rotational spindle speeds. One is going to be much faster in response time (SSD's), while the other is usually going to have higher throughput bandwidth (HDD's). Additionally, there are certain factors which can affect the results of a test which we do our best to avoid.

Solid State Drives have traveled a long winding course to finally get where they are today. Up to this point in technology, there have been several key differences separating Solid State Drives from magnetic rotational Hard Disk Drives. While the DRAM-based buffer size on desktop HDD's has recently reached 32 MB and is ever-increasing, there is still a hefty delay in the initial response time. This is one key area in which flash-based Solid State Drives continually dominates because they lack moving parts to "get up to speed".

However the benefits inherent to SSD's have traditionally fallen off once the throughput begins, even though data reads or writes are executed at a high constant rate whereas the HDD tapers off in performance. This makes the average transaction speed of a SSD comparable to the data burst rate mentioned in HDD tests, albeit usually lower than the HDD's speed.

Disclaimer: SSD Testing

Benchmark Reviews recently published an article which details Solid State Drive (SSD) Benchmark Performance Testing. The research and discussion that went into producing that article changed the way we now test SSD products. Our previous perceptions of this technology were lost on one particular difference: the wear leveling algorithm that makes data a moving target. Without conclusive linear bandwidth testing or some other method of total-capacity testing, our previous performance results were rough estimates at best.

It's critically important to understand that no software for the Microsoft Windows platform can accurately measure SSD performance with perfect precision and in a comparable fashion. Synthetic benchmark tools such as HD Tach and ATTO Disk Benchmark are helpful indicators, but should not be considered the ultimate determining factor. That factor should be measured in actual user experience of real-world applications. Benchmark Reviews includes both bandwidth benchmarks and application speed tests to present a conclusive measurement of product performance.

Test System

  • Motherboard: Gigabyte GA-EX58-UD4P (Intel X58/ICH10R Chipset) with version F7e BIOS
  • Processor: Intel Core i7-920 BX80601920 @ 2.667 GHz
  • System Memory: 6GB Tri-Channel DDR3 1600MHz CL6-6-6-18
  • Operating System: Windows XP Professional SP-3 (optimized to 16 processes at idle)

Drive Hardware

Test Tools

  • System Speed Test v4.78 by Vladimir Afanasiev: Accurately measures random access response time
  • ATTO Disk Benchmark v2.34: Spot-tests static file size chunks for basic I/O bandwidth
  • HD Tune Pro v3.5 by EFD Software: Measured random access IOPS and speed
  • Iometer 2006.07.27 by Intel Corporation: Tests IOPS performance and I/O response time
  • EVEREST Ultimate Edition v5.00.1650 by Lavalys: Disk Benchmark component tests linear read and write bandwidth speeds
  • CrystalDiskMark v2.2 by Crystal Dew World: Sequential speed benchmark spot-tests various file size chunks
  • HD Tach RW v3.0.4.0 by Simpli Software: Measures approximate buffered read and write bandwidth speeds

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.

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
