Kingston 32GB microSDHC Mobility Kit Review




To test Kingston's 32GB class 10 microSDHC card, I will run a series of benchmarks to provide as accurate a representation of its performance as possible. Flash Memory Toolkit and SiSoft Sandra will both be used to measure access times and to benchmark read and write speeds in various circumstances. Remember that FMT and Sandra are, however, synthetic benchmarks. To gauge real-world performance, I will also use a set of compressed files of various sizes to measure write speeds under typical usage. These compressed files correspond to those that are used in our product reviews that use the WinRAR benchmark. Let's begin!


Testing Setup:

  • Processor: Phenom II x6 1055T
  • CPU Cooling: Noctua NH-C12P-SE14
  • CPU Fan: Noctua NF-P14
  • Motherboard: Gigabyte GA-890FXA-UD5
  • Memory: 2 x 4GB G.SKILL SNIPER DDR3-1333 9-9-9-24 2T
  • Video Card: XFX HD6970 2GB + BFG 8800GT (PhysX)
  • Hard Drive: Seagate Barracuda 7200.12 750GB
  • Optical Drive: ASUS DRW-24B1ST
  • Power Supply: XFX BE 850W
  • OS: Windows 7 Ultimate x64
  • Storage Card: 32GB Kingston Class 10 microSDHC


Comparison Storage Cards

  • 1GB Norcent SD
  • 2GB PNY microSD
  • 8GB Kingston Class 4 SDHC
  • 8GB SanDisk Ultra II Class 2 SDHC
  • 16GB SanDisk Ultra II Class 4 SDHC
  • 32GB Patriot Class 4 SDHC


The order of the results will be as listed above from left to right. There are also two results for the Kingston 32GB microSDHC card, as it was tested the same as the other SD and microSD cards using a SanDisk MicroMate SD to USB adapter and with the included microSD to USB adapter.


Flash Memory Toolkit 2.0 - Low Level Benchmark:

The first benchmark will use the low level benchmark from Flash Memory Toolkit 2.0. Higher read/write speeds, and lower access times are better.




Initial results look good. Read speeds don't show much variance, though it isn't unusual for this to be the case. Write speeds are a better indication of how fast a memory card is, as they are arguably the more important of the two, especially if the read and write speeds differ drastically. Write speeds show more variance, and although SanDisk's high end Ultra II offerings blast away the competition, Kingston's 32GB offering does fare well overall. Using the Kingston-supplied microSD to USB adapter showed small improvements in both read speed access time. This seems logical, since using the included USB adapter shortens the electrical pathway to the card.
