Voyager MINI Slow Write Speed compared to another Voyager MINI

[mwhdvm]

I have purchased 4 32GB Voyager Mini drives. I have found that all of them work but 1 of the drives (possibly 2) writes very slowly compared to the others. I use them in an ultrasound machine and the file sizes are consistent and I save hundreds of images a day. I'm very used to how long it takes to write a file. One of the drives (possibly 2) seems to bog the ultrasound machine down for 1-2 seconds when it begins to write when compared to one of the other drives which writes very quickly with almost no delay.

 

Is there a solution to fix this? I formatted the slowest drive in my MacAir but it didn't seem to change anything.

 

Thank you

If you can reformat the drive in a Windows system with the SDCard.org Flash format Utility Or if you go to their site there is a version available for MAC . If that does not solve this for you, please use the link on the left and we can replace them.

I did as you suggested and I also downloaded a flash memory speed test app. What kind of write speeds should I expect from these drives. The main drive I use every day in my ultrasound machine writes at ~23mb/s and reads at ~33mb/s. The other 3 drives I have all write at ~14mb/s and read at ~22mb/s. It is a noticeable difference when compared to the first drive in how these perform. What is an expected write/read speed?

 

Thank you!

We do not publish a spec for these drives because the target for these drives are their size not performance. But what you have reported is with in what I would call normal.
