are system image backups done with sequential reads
>t. guy from last thread
One of them better be a female.Faggots belong on a stake.
I'm fairly certain it's sequential
Both are male!
thanks!!!
but windirstat runs very slowly @ 500kbps and its just scanning the drive, are random reads meant to be this slow?

yes

>Well, if that next block is somewhere else on the disk, you will need to incur the same penalties of seek time and rotational latency. We call this type of operation a random I/O. But if the next block happened to be located directly after the previous one on the same track, the disk head would encounter it immediately afterwards, incurring no wait time (i.e. no latency). This, of course, is a sequential I/O.
so that makes system image backups random reads then?
or is it sequential because it works its way from the top
Again, I think it's sequential, because it's not looking for specific blocks or files or anything for the image. It's just grabbing the whole thing and making an archive of it.
thanks user!
it made me think that it was random because i misunderstood, since windirstat *is* probing specific files, right?
