If you see a significant speed difference between mke2fs and running wiper.sh on that same filesystem immediately after formatting, then their is likely a bug worth chasing.
You're right. They're both equally slow on a blank Sandforce drive, taking about 83-90 seconds to TRIM 100GB. The difference being that mke2fs just sits there with zero indication or information as to what the huge delay is. It's a pity the TRIM commands are so sluggish on the Sandforce. It's a generation newer than the original Vertex, and TRIM is way faster on the older Vertex. Not that either of them do it quickly enough that I'd ever want the kernel doing it automatically "on my behalf". The strange thing, is that when we TRIM the entire raw device, using ATA SECURITY ERASE, it takes less than 2 seconds.
