Hi all,
Google is giving me conflicting answers to this question, so I thought
I'd try asking real people instead :o)
Hard drives with multiple platters & therefore multiple heads: When
writing to the disk, is only one head active at a time, writing the
whole file to one platter; or do all the heads write at once, with
head one writing the first bit of the file, head two writing the
second bit, and so on?
I was under the impression that only one head could write at any one
time, and most sites seem to bear this out, but others swear blind
that all platters are written to at once, and you can see how that
would make for a speed increase. . .
Anybody know for sure?
Thanks
Dominic
