Do modern harddrives cache the data that appears under the head ?[edit]
And how much data is cached this way ? Assuming that a modern drive stores 1 TB on a single platter, and that the shape of a bit on a drive is approximately square, I calculate that such a disk must have between 1,600,000 and 1,100,000 tracks, each storing up to 5 M bits. —Preceding unsigned comment added by Nroets (talk • contribs) 17:55, 2 December 2010 (UTC)[reply]
20th century tracks were always many times wider than the length of a bit or even a byte and I assume the same is true for modern ones. Jim.henderson (talk) 13:27, 4 December 2010 (UTC)[reply]
You do make a valid point. But it is somewhat counter balanced by the presence of error checking / correcting and other headers inside each track. My calculation was also based on the incorrect assumption that a disk is single sided. -- Nic Roets (talk) 05:49, 6 December 2010 (UTC)[reply]
