   That's not really correct.  ext4 is a lot more than ext2 with   
   journaling added.  You're probably thinking of ext3, which is indeed   
   basically ext2 with journaling, albeit that even ext3 supports hashed   
   trees — they're disabled by default but they can be enabled — which   
   ext2 did not support yet.   
      
   ext4 uses hashed trees and extents, rather than blocks, and it caches   
   more aggressively. So even with journaling disabled, it'll still be   
   quite a bit faster than ext2 or ext3.     
      
   ext4 also has performance optimizations for SSDs — e.g. it'll use a   
   different I/O scheduler by default when the "ssd" mount option is   
   specified — which its predecessors didn't have yet.   
      
   That said, considering that they are (removable) SSDs, the OP may even   
   consider other options than ext2/3/4, such as F2FS, YAFFS2, et al.   
   F2FS for instance has already long been a mature filesystem and was   
   specifically designed for flash-based storage.
