Lets look at the math a little bit:
To do 35GB in that time it is 35840MB/5 Minutes. That gives you 7168MB/Min. Which is in turn 119.46MB/sec. You said less than 5 minutes so it needs to be even faster than that...
Here is it benchmarking a burst speed of
111MB/Sec.
Burst speeds are always faster than sustained.
That drive is damn fast for a 7200rpm drive, but its not fast enough to do 35gigs in 5 minutes. TomsHardware benched the drive vs a lot of others,
here is the page with the important results. The drive was a fair bit faster than I expected, with a Max of 106MB/sec, Ave of 85MB/sec, and a Min of 54MB/sec for Sequential Write (Read speed is similar). The next page of the review has a PCMark 05 bench of the Write speed, where it shows 95MB/sec.
Not even the highest speed (burst) for that drive from 2 different sources is high enough, let alone the average speed which you'd be much closer to on a 5 minute transfer. If that was a 1 file 35GB transfer I could see it being close to the max for that drive, but like I said, the max for that drive is lower than the transfer speed you needed to achieve to do it in 5 minutes. Maybe you just read what Windows said was the time remaining initially and just believed that.
With an average speed of 85Megs/sec you actually get closer than I expected. It would get the transfer done in just over 7 minutes. But for a backup you are probably dealing with a lot of small files which will cripple the speed.
I've now linked 3 sources between 2 posts.
I get that arguing about transfer speeds isn't solving your real question here. But I can't just stand by doing nothing when I see something that is not correct.
