Personal Storage Media Speed BenchMark

Comments are closed

I was working with videos and our family photo library  over the weekend (another post coming) and was having some challenges with storage and disk drives

I had a bit of time time tonight, and my hotel had terrible Internet access speed  so I decided to  take some time and do a quick comparison of speed across several of the media storage I personally use.  

First I had to look for a good and easy to read disk speed benchmark product.    There are many out there, but the one I chose was CrystalDiskMark   Good reviews, easy to use, recently updated  and free open source.  

Once I had the software, I just need to run the test on the different storage disks  I use.  

After playing with the tool, I decided to use the following parameters: 

  • Same Computer for all tests (Dell XPS 13 core i7)
  • 50Mg file for the tests
  • Number of passes per test:  5
  • Run all tests available (4): 
    • Sequencial Read/Write:  32 queues / 1 thread
    • Random 4Kb Read/Write: 8 queues / 8 threads
    • Random 4Kb Read/Write: 32 queues / 1 thread 
    • Random 4Kb Read/Write: 1 queue / 1 thread

I was completely surprise by the delta difference in speed between the different devices.

The SSD  drive on the computer benchmarked at 429 MB/s while a 128Gb MicroSD U1 card clocked at  10.5 MB/s  —   What a difference!    

It was a cool test to do…

As an FYI the very slow microSD card I tested  was a PNY  128Gb U1 XS-I   cards
