cheap 3TB

WD30EZRS w/64MB cache is cheaper to buy in an external enclosure.

3.0 TB is actually 3 × 1000⁴ / 1024⁴ = 2.7 TiB.

WD30EZRS has 5 860 533 168 logical 512 B sectors or 732 566 646 physical 4096 B sectors.

WD20EARS has 3 907 029 168 logical 512 B sectors or 488 378 646 physical 4096 B sectors.

HD204UI has 3 907 029 168 logical 512 B sectors or 488 378 646 physical 4096 B sectors.

Going to use this disk in my linux server as unpartitioned superfloppy (no need for mbr / gpt) xfs filesystem mounted at /media. That way I don't have to worry at all about the 4 kB alignment issue with these "Advanced Format" drives.
