My feeling is that 4K blocksize are more often seen on disk-sizes 3Tb and up. I have some WDC 3Tb and some Seagate 4Tb drives for my mythtv setup, I'm certain they're all 4K.
Here's one in-store even being advertised as 512bytes sector:

Hmm, I was too fast there. I guess 512e means something else - this is the datasheet, those drives seems to come in two versions - 512e(mulation) and 512n(ative) :

512e means emulation mode - underlying physical sector size is different (probably 4K) but it pretends to have 512B to outside world. 512n is native 512B per sector. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
