X25-E Transfer Diagram
The X25-E doesn’t provide throughput that’s as steady and controllable as on a hard drive, especially on writes, but the overall performance is still more than impressive. Bear in mind that this isn’t a drive one would buy for its throughput; modern 15,000 RPM hard drives aren’t too far away from these numbers at only a fraction of the cost. The X25-E was made to dominate in I/O performance, as you’ll see on the following pages.
