Toshiba HG5D Series SATA M.2 SSD Review (512GB) – Amazing Performance in a SATA M.2 SSD

PCMARK VANTAGE X64 HDD SUITE

The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:

  • Windows Defender In Use
  • Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
  • Importing digital photos into Windows Photo Gallery
  • Starting the Vista Operating System
  • Home Video editing with Movie Maker which can be very time consuming
  • Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as XBox
  • Cataloging a music library
  • Starting applications

TOSHIBA HG5D CSSD 512GB SATA M.2 SSD VANTAGE RESULTS

The Toshiba HG5D M.2 cSSD Pulled through Vantage testing with a Total Score of 71137 points and a high transfer speed of 431MB/s while testing in Media Center.  This result is very indicative of that 109MB/s low 4K random write performance seen earlier.  Very encouraging is the fact that seven of the eight test results were excellent SATA 3 speeds.

Our Hierarchy chart below lists only M.2 and mSATA form factor SSDs as both are very similar.  The only factor considered for chart placement is the PCMark Vantage Total Score and the Samsung M.2 PCIe SSD is only included to demonstrate the vast difference between SATA and a native PCIe SSD.

REPORT SUMMARY AND FINAL THOUGHTS

When we consider the fact that a native M.2 PCIe SSD can provide more than twice the performance of a SATA based M.2, the question that came to mind was why manufacturers wouldn’t simply make the move to native M.2 SSDs completely.  We spoke with a few manufacturers regarding this and the common thread evident in all conversations was the increased power usage that the native M.2 will require in its high transfer speeds, reducing precious battery life.  The fact that SATA wasn’t going anywhere anytime soon, as well as SATA 3 speeds being more than enough power for the typical user, were also valid points considered.

Although not being a consumer retail SSD, the Toshiba HG5d cSSD is an excellent example of what SATA 3 M.2 SSDs can provide.  It is a low power and high performing M.2 form factor, one that provided one of the top 4K random write results we have seen to date.  The Toshiba 512GB M.2 is a great example of where we have come in the SSD arena and Toshiba’s partnership with Marvell in the development of their SSD controller just may have resulted in one of the best controllers available today, certainly indicative of an upper tier product.

FINAL THOUGHTS

Between Technology X and the SSD Review, we have been fortunate to get our hands on all of the latest Toshiba cSSD form factors, as well as their newest Q Series Pro SSD which earned our Top Value Award. Heck, the Toshiba M.2 SSD has still only been reviewed here and we thank Toshiba for that honor. At the end of the day though, we wanted to put a final grade on the Toshiba cSSD from the perspective of having looked at all three form factors, the M.2, the mSATA and the 2.5″ Toshiba cSSD. With this in mind, we have decided that the Toshiba client family of cSSDs is deserving of our Gold Seal Standard.
