I'm curious if anyone knows whether this affects "real world" speeds.<p>I know, for example, that a multi-GB copy on a brand-new Mac is blazingly fast as the SSD is "virgin".<p>But that once I've filled up the disk, added and deleted and modified the disk's capacity many times over, and keeping it usually around 80-90% full, that the speed is nothing what is what like out of the box. Certainly seems to me by more than a 2x slowdown.<p>So even if there's a new bottleneck that reduces the maximum SSD speed to 50% in the worst case... is it even noticeable or relevant if there's a bigger bottleneck related to regular, day-in-day-out SSD usage?
