512B sectors soon to be an anachronism
« 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:

Gigabyte GA-EP45-UD3P / Intel Celeron Dual Core E1400 2.0 GHz / 800 MHz FSB / ASUS EN8400GS Silent/HTP/512M PCIe x16
4GiB (2x2) G.Skill DDR2-10666, PC2-8500, 2048MB x 2, CL-5-5-5-15 2.0~2.1V DRAM / 750 GB Seagate Barracuda 7200.11 SATA HDD ST3750330AS / hp dvd1170i SATA DL DVD
EFI (empty) / iPC 10.5.6 / Win 7 pro x64
... oh yeah, and an i7 17" MBP
