I’m not sure I understand that response.
Roughly data leaves a 5400 rpm drive head at 772.5Mb/sec, and a 7200 rpm drive head at 1030Mb/sec.
Now, they are both well under the USB 3.0 interface speed of a little under 5Gb/sec.
Yes, there is no doubt a Buffer Cache between the Drive head(s), and the USB interface, that helps boost burst transfers, but for sustained transfers, the higher speed rpm drive would perform much better than the lower speed rpm drive.
Hence I would much rather buy a 7200 rpm Portable Drive, than a 5400 rpm, and hence this question, where I’m trying to determine which WD Portable a drives spin at 7200 rpm.
Feel free to correct my understanding… I may be wrong.
