Thanks. Just noticed that the Hitachi 3TB drives are not available. The
4TB ones are but with 512b emulated only. However I can get Barracudas
7200.14 with supposedly real 4k quite cheap. Anyone any experience with
those? I might be getting one or two more and go for z2 instead of z1.
What makes you think the Barracuda 7200.14 drives report 4k sectors? I
gave up looking for 4kn drives, as everything I could find was 512e. I
would _love_ to be wrong, as I have 8 4TB Hitachis on backorder that I
would gladly replace with 4kn drives, even if I had to drop to 3TB density.
From page 11 of
Formatted capacity (512 bytes/sector)**
Bytes per sector (4K physical emulated at 512-byte sectors)
From the smartmontools list,
Sector Sizes: 512 bytes logical, 4096 bytes physical
