Rather, question is how to deal with the 4kB block size!

64MB 2TB work OK in OI148??
I can confirm,
As they "emulate" 512 sectors, yes they will "work", _but_ not as well
as Hitachi and some other brand/models, and definitely not recommended
with expanders.
Also sector alignment may need to be tinkered to improve performance.
The major issue is the fixed and very long TLER setting, which will
cause driver time-outs, especially under load.
Solaris doesn't tolerate this well, and linix isn't too fussed with raid
sets of them either.
I managed to lock up a server last week with sata bus errors on a triple
esata setup with wd20ears disks (raidz LTO5 alternative) with bacula.

Or are there any gotchas?
I intend to put 4 identical ones, as mirrored pairs in ZFS.
It's on a SuperMicro XB7Si motherboard, the 4 onboard SATA connectors
left after the system rpool's 2 500GB Seagate Barracuda.
These will serve up media files as an SMB/Cifs share (iSCSI??) for
various media players
