Just a few questions about hard drive/Ram

[ChessAddict]

Does the chess engine use the ram mostly when doing position searching? Does it ever revert to the hard drive?

[hgm]

Normally engines only use the hard drive for tablebase probing and opening book,

The only other things which come to mind are:

1. Some engines write to a logfile after each move. That can be quite annoying if your HD is loud, but in almost all cases it should be possible to switch it off in the ini file.

2. Some engines write to a learnfile, but not constantly (not after each move).

Both does not cause big HD activity.

And virtual memory hard disk r/w when you run out of available ram.

Yes, but this is exactly what you should never allow to happen, as it will slow down your engine 1000-fold or more.
