... for various values of "faster" and "scalable".
For example, in the case of gluster, I haven't seen any references to PB-sized filesystems. But gluster likely handles small files better. Both are measurements of scale, but is one more scalable than the other? Depending upon use case, obviously yes.
As Hadoop gains in importance, we're seeing more and more of these type of overly broad statements. Consumers just need to be smart and do their research to find the correct bits for them. I just hope folks actually dig into the details before spending their cash.

I don't think it is a matter of 'beating' them. Certain environments have needs that aren't met by HDFS and they will go out looking for alternatives. Competition is also good in the sense that it drives people to improve the base stuff. (The sudden importance of HA in certain camps is a great example of this.)
Besides, for a lot of these commercial companies, the fact that they aren't submitting (viable) patches to be included in Apache Hadoop puts them at a disadvantage from the start.
