Personal Storage Media Speed BenchMark

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…

Details below: 

Read Test (in MB/S) Sequencial
256GB SSD Drive 429.7 128.6 63.3 26.1
256 USB Stick 79.0 6.2 6.1 5.7
128 USB Stick 72.8 2.8 3.2 2.4
1TB Disk Drive 62.5 0.7 0.6 0.5
128GB MicroSD Card 10.5 5.7 5.4 4.9
Write Test (in MB/S) Sequencial
256GB SSD Drive 173.8 25.1 41.6 18.9
256 USB Stick 21.0 1.4 1.4 1.2
128 USB Stick 62.3 1.1 1.2 1.1
1TB Disk Drive 67.7 1.6 1.6 1.4
128GB MicroSD Card 5.9 0.1 0.1 0.1

Another way of looking at it: 










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