What's up with these? They have 32/20Mb/s. A normal SSD has like 170/100 MB/s.

Notice the Mb/s vs MB/s though. These can reach upto 1000 MB/s. Are they good though? I can't find any reviews. Are they better than normal SSDs? Like the Crucials, Intels, OCZs etc.

I assume you mean the Express card interface bandwidth is 1000 MB/s.

No they won't be better than normal SSD's at 32/20 Mb/s, The interface bandwidth makes no difference if the actual SSD itself is the bottleneck.

Is 32/20 Mb/s faster than 170/100 MB/s?

No
8 bits to a byte, so 8Mb == 1MB. Therefore 32/20 Mb/s == 4/2.5 MB/s which is very slow.

Well, lol. Thanks for clearing that up. Me and a friend was confused thinking Mb was faster than MB.
