popular for dagta/program storage and transfer because of
their small size, high data capacity, and immunity to
magnetic fields typical of airport scanners.
I just came across a bench marking program that may be of
interest to the group for these devices. You can download
it for free at
Some takeaways from the few benchmarks I ran:
There is a difference in the read/write speed between
brands. The one new micro flash drives I checked was slower
than the full size drives.
You can see the difference between class 4 and class 10 SD
cards. For data transfer/storage most likely no practical
difference. If you are using a SD card or flash drive as a
"ReadyBoost" drive you may see a difference.
The older flash drives in addition to having less capacity
are also slower. Again, this may or may not be of
significance depend what you are using them for and the
amount of data you are dealing with.
Still amazes me that you can get 128GB of data into a SD
flash card smaller than a postage stamp. The micro sd cards
are even tinier.
