Posted 13 September 2016 15:00 CET by Wendy Robertson

Myce Reality Suite revision 4.

NOTE: New in revision 4.

  • Support for NVMe
  • Support for SATA Express
  • Support for PCIe
  • Support for M.2.

So what is the Myce Reality storage test?

The Myce Reality Suite of tests is made from real everyday applications and real data, there are no simulated tests, and everything is in the real world. The only thing that's synthetic is that everything is automated to make the tests fair, no matter which drive the tests are run on.

Recorded user sessions, by means of a script, are used to launch the applications, load data, edit data, and then finally write that data back to the target drive. The scripts do load the system much more than a human could with these tests, as the scripts do not make mistakes, or pause to think about what has to be done next.

Measurement system

The measuring system is part hardware and part software. The hardware is a two part system comprising of a host PC and an external hardware analyser which is proprietary, and runs a proprietary version of Linux with special software.

The host PC is built around an Intel Core i7 2600 (Sandy Bridge) CPU, and an Asrock Z68 Extreme 4 motherboard, with 8GB of 1600MHz DDR3 RAM. The interface between the host PC and the external measuring system uses a proprietary PCIe2 x8 card, which is housed in the primary PCIe2 x16 slot on the host PC. The analyser is calibrated before the start of the tests, and is guaranteed to be accurate to within 0.03%. 

Testing method.

Previously the test platform was Windows 7 Home Premium 64bit. The transition to Windows 8.1 Professional 64bit has now been made, and at the same time a couple of new tests have been validated and introduced. This has of course meant that I have had to retest a selected number of SSDs on the new platform, and the results from SSDs that were old, or no longer available in the test labs, have been discarded.

Building the tests and test image.

Once all the test data files and the scripts that run the tests were complete, they were then copied to a single folder. I then fitted an 120GB SSD into the PC and did a clean install of Window 8.1 Professional x64. The latest hardware drivers were installed and Windows update was run to install any new updates that were available up to 24/11/2013. At this point the applications that were to be used in the tests were installed and updated with the latest patches.

The folder containing the application test data files and scripts was then copied over to our fresh Windows 8.1 Professional 64bit SSD. A drive snapshot was then taken of the complete SSD and the drive snapshot image copied to an HDD for safe keeping.

The image is then simply restored to each of the SSDs on test. After imaging the drive the partition is then realigned “on the fly” and the free space is filled and then deleted to force TRIM. A 20 minute settling time is allowed before the tests are run, then each of the 6 tests is run and the results gathered. This process is repeated for each of the drives I am testing.

The test scenarios are as follows.

  • Graphics content
  • Video editing
  • Audio import and compression
  • Application multitasking
  • Windows defender (full system drive scan)
  • GRID 2 gaming test.

Let’s begin the tests.


Myce Reality Suite – Graphics content.

Using ACDSee Pro 3, 100 JPG pictures with an average size of 10MB are imported into the ACDSee library, and then 12 of these JPG files are then selected for a batch process, of resize, compress the quality to 80%, and finally write the edited pictures back to the drive. The test is approximately 78% read and 22% write, with an average queue depth of 1.98.

The Toshiba OCZ VX500 512GB performs well in this test, and finishes in fifth place.


Myce Reality Suite – Video editing.

Using Vegas Pro, a 14GB HD MPEG2 video stream is loaded into the editor, from which 2 segments are then cut and pasted into new segments. There is a lot of disc caching going on in this test, which is approximately 55% read and 45% write, with an average queue depth of 1.89.

This time the Toshiba OCZ VX500 512GB SSD finishes in third spot


Myce Reality Suite – Audio import and compression.

Using Sony Sound Forge 10, a batch process is run consisting of importing 30 24bit (192000 Hz sample rate) .wav files, and 100 16bit (44100 Hz sample rate) .wav files  which are converted to MP3 audio files with a bit rate of 128kbps, and the MP3s are then written back to the drive. The test is approximately 72% read and 28% write, with an average queue depth of 2.62.

This time the Toshiba OCZ VX500 512GB takes fifth place.


Myce Reality Suite – Application multitasking.

For this test I used several popular applications, Microsoft Word 2007, Microsoft Access 2007, Microsoft Excel 2007, Microsoft Outlook 2007, Adobe reader, Adobe Photoshop CS3, uTorrent, Windows media player, and Internet Explorer 9.

This session runs for approximately 12 minutes. The test is started by downloading a Linux distribution via uTorrent, Windows media player is then opened, and a 1080p video file is opened and played for the duration of the test. Microsoft Outlook is opened and any new emails are received, read, then replied too, a document in Adobe reader is opened and scrolled from start to finish, 3 Microsoft Word documents with graphics content are opened, browsed and some sections of the documents are copied and pasted into a forth document and then saved back to the drive. The same applies to Microsoft Access and Excel. 100 MP3 files are imported into Windows media library. Six JPG images are loaded into Adobe Photoshop and some minor editing is done and the files saved back to the drive.

Finally, Internet Explorer 11 is opened with 10 tabs, and the contents of the 10 tabs refreshed, and browsed while the other applications are busy in the background.

I would describe the multitasking pattern as moderate to heavy.

During this test there is approximately 85% reading and 15% writing, with an average queue depth of 6.73.

With the higher queue depths in this test the Toshiba OCZ VX500 512GB SSD is able to show what it can really do, when pushed hard, and performs well, finishing in third spot.

Windows Defender (full system drive scan)

A full system drive scan is selected on drive C:\ and then run. The test is approximately 99% reading and 1% writing, with an average queue depth of 1.2.

The Toshiba OCZ VX500 512GB SSD has performed extremely well in this test, finishing in second place.

GRID 2 gaming test

The game is launched and then a pre-saved level is loaded. The test runs until the loaded level starts. The test is approximately 98% reading and 2% writing, with an average queue depth of 1.

The Toshiba OCZ VX500 512GB SSD has performed very well, and takes second spot.

Summary

I firmly believe that the Myce Reality Suite gives a very good overall picture of how a drive can perform in the real world and, in this case, the Toshiba OCZ VX500 512GB SSD is clearly a very capable performer.

 

Now let’s head to the next page, and see how well the drive performs after heavy use....
