Title: 512B sectors soon to be an anachronism
Post by: jbreher on July 20, 2010, 10:47:51 PM
I've known for some time that HDDs would be transitioning to larger sector sizes. What I did not realize until this week is that all major drive manufacturers are committed to making this transition very soon.

"Beginning in late 2009, accelerating in 2010 and hitting mainstream in 2011, hard
drive companies are migrating away from the legacy sector size of 512 bytes
to a larger, more efficient sector size of 4096 bytes, generally referred to as 4K
sectors, and now referred to as the Advanced Format by IDEMA (The International
Disk Drive Equipment and Materials Association)"

If you are not yet thinking about the implications of this change, it's time to start the process.

Here's a lovely white paper on the matter:
