"However, by modifying the length of the data field through the implementation of Advanced Format using 4096-byte sectors, hard disk drive manufacturers could increase the efficiency of the data surface
area by five to thirteen percent while increasing the strength of the
ECC."
So, sticking with 512 byte sectors effectively wastes 5 to 13% of the
potential storage on the platter due to inefficient headers/footers.
You should buy what works best for you, but I suspect over 95% of users go with the default 4kb filesystem page.
No, that doesn't matter at all to a user. If I buy a 1 TB disk, it will
have 1 TB useful space no matter if organized internally in 512B blocks
or 4K blocks.
It only matters to the manufacturer, that he needs less surface for providing the same storage space. Hopefully that is translated to the users in lower prices. Maybe not.
As a consumer, it's that I get more capacity for my money. Recently I've been buying 1TB usb drives for $60 or so (at Costco). Yesterday I bought a 1.5 TB usb-3 drive for $59 (at Costco). That's the cheapest I've ever seen them. It's also a size I don't recall seeing often. So, things like 4KB sectors get us as consumers more for our money. I haven't checked the specs, but I'm open to a bet that these 1.5TB drives are 4KB sector drives. Greg -- Sent from my Android device with K-9 Mail.
