I tend to realize that the failure rate of USB is far more higher than,God forbid, the historic diskette.In a few weeks I have lost a couple of these devices and thereby my sweet documents!
NKT.

I now tend to migrate to SD and microSD;whats your take or advice?
d'oh!

Two completely different things. USB is an interface (method of connecting) that is used to connect devices like cameras, phones etc to computers. It stands for universal serial bus. The other one SD is a memory card (for storing things), and stands for secure digital. Note that SD memory cards can connect to computers using USB if the reader has a USB interface.
I suspect you wanted to compare flash disks that have USB interfaces to SD disks.
If so they are different in that a flash disk requires no reader/writer as these are inbuilt while an SD card needs a reader/writer like a phone or camera.

How often do you erase/write data to them? All flash based memory storage devices are prone to memory wear and manufacturers only guarantee file integrity before a certain number of writes.

Personally I have used both. One of my flash drives has been in use since 2007 with no issues and my SD card has only just started to have read errors though removing then reinserting fixes it for now.

Try formatting your flash drive, maybe there is some bad data on it. Also, if you get some of those counterfeit drives that claim to be 8 or 16GB, get a flash memory tester. Some of those drives are actually less than the stated capacity. I bought an 8GB drive and ran the tester, turns out it is only 4GB so I get errors on anything higher than that.

IMHO stick with flash drives.

Maybe you need to look at the type/make of flash disk you buy. i have noticed that sony is one of the useless types. lately i am using sandisk cruzer and so far so good.
