Because I'm becoming addicted to building FreeNAS systems, I'm constantly buying hardware. Usually it's on a budget, so I tend to work with what I have, not with what I want.
Currently, I'm sitting on a mix of Seagate Constellation drives, pulled from a data-center somewhere. They are a mix of ST4000NM0033 (4x) and ST4000NM0034 (7x) drives. 11 units, all <10000 hours, perfect health record.
€45 a piece - a fun bargain! This is intended to be built as home storage for housing backups and possibly for some media-streaming, so high performance is not especially critical, though I always want to optimize, of course.
The *33 are SATA and 512-byte native, the *34 are SAS and 512-byte emulated. According to Seagate datasheets.
I've mixed SAS and SATA often, and that seems to always work fine. But afaik, mixing 512n and 512e is a new one for me.
Before I commit for the lifetime of this RAIDZ3 pool, is my own conclusion correct: all this needs is an ashift of 12 and we're good to go...?
