Sandisk USB Flash Drive Speed Comparison
Sometimes there is such a thing as too much choice. USB flash drives certainly fall into that category.
With dozens of manufacturers all touting the same memory sizes what separates one drive from another?
Packaging is one thing. Every manufacturer or subcontractor have their own vision of how to wrap plastic around the USB connector. Caps, no caps, foldable ones, extra rugged drives, slim ones even flash drive SD cards with a foldable USB connector.
The other less obvious difference is drive speed. Not all usb flash drives are the same speed. Speeds can vary by two to three times from manufacturer to manufacturer. This is why flash drive companies tend to be cagey about the speed of their usb drives.
You are lucky to find any sort of file transfer specification on the packaging from even name brand manufacturers. Often the purchaser is given no data on the file transfer speeds of the drive they buy.
This may be fine if you do do occasional backups or deal with relatively usb flash memory transfers but a 1 gig to 4 gig transfer can on average take anywhere from one to five minutes.
That is why we need more speed tests like this from the slashgear guys to see exactly what you are buying.
They do a write and read speed run on a couple of Sandisk usb flash drives but it looks like the Lexar USB Jumpdrive beats them both by a wide margin.
