Given choices, I used NFS. Samba is great for cross compatibility, but
CIFS is a very chatty protocol with some longstanding complexities
leading to awkward access control in my experience.

That said, I've built a render cluster with 200 nodes running a 40
TByte storage setup with Samba 3.x for the Windows clients and NFSv3
for the SuSE users. It worked much better than the commercially funded
storage array. (Ran headlong into the 2 TByte storage size issue due
to 32-bit fiber optic controllers, but split it into 4 10 TByte

I also did the first published ports of Samba to SunOS 4.1.x, so I've
done a *lot* of setups.

More building them up from scartch as part of other services. For
commercial NAS support, I've been dealing a lot with NetApp, which
incorporates a lot of the mirroring and snapshots and high performance
issues an off the shefl USB disk storage box won't have. Those do play
nicely with Samba, AD, and usually NIS as well.
