With too many USB drive manufacturers, a user can slightly get into the dilemma of which USB flash drive to purchase. Buying a USB drive on the criteria of fast transfer speed is not a wrong choice. If you are low on budget and want a lightweight speed test software, then SpeedOut and USBDeview are a clear-cut option.

Also, if you are looking for a data recovery and restore option, you can try Flash Memory Toolkit software. But, there isn't any new version available for it, and it isn't freeware. I recommend Wondershare Recoverit Data Recovery Software as its alternative, which provides services on any OS platform and gives free 100 MB data recovery. To seek advanced functions you can also buy it with a favorable price.
