It might be OK if you are using it for the occasional transfer of files from one computer to another, but if you are going to be doing lots of updates, your data is going to be at risk no matter what file system you use. Some filesystems are more performant than others, so keep in mind that a simple way to double the lifetime of some cheap crap is to slow down the write speed by a factor of two. :-) So I wouldn't so much focus on whether some storage device is "good enough for ext3/4", but rather, "is it good enough given the value of the data of the data I'm storing on it, and the read/write patterns I'm going to be subjecting the drive to"?
