Are larger drives more efficient?

I doubled the size of the HD on both my TiVos yesterday and all functions seem to have speeded up considerably...or am I just imagining it?

Could be: drives of the same general type have similar seek times -- regardless of size, i.e. they can all do a 50% head swing equally fast. But a bigger drive doesn't have to move as FAR to get data that is X Mb away, so it gets the same data faster.

So if things that are seek-limited are causing your impression of "speed" it will indeed be faster -- in about the ratio of the old and new disk sizes.

Of course, you have the same increase in packing along the tracks too - the disk doesn't have to turn through as many degrees to read/write the same amount of data.

I'm sure it'll slow down again as it fills up, though!

Also (assuming that you used the MFS tools to make the upgrade) certain options commonly recommend can also improve performance.

And the stock harddrives are only 5400 rpm, so it is possible that you upgraded with 7200 rpm models which would be faster.

So it is possible that the performance increase is real. On the other hand you just might be delusional ;)
