What do you know today that you didn't know yesterday?

The 3Ware 9650se sata raid controller isn't a good HBA.  The Xeon E3-1230 V2 has hyperthreading while the E3-1220 V2 doesn't.  Okay.  I know.  Nobody cares.

I haven't seen enough real-world programs to convince me that hyperthreading is worth it.  After all, on modern processors, how deep is the pipeline?  Ten, fifteen stages?  What's the benefit with having two threads on the same core??  If one stalls, the other can continue?  Is not 12 physical cores enough???

These processors only have 4 cores. Six threads/cores is considered the place to start these days. Since these are for a file server, the extra threads will likely be a benefit. Anyway, the Xeons without hyper threading are $10-15, and the ones with hyper threading are only $10 more. At that price it's a no-brainer.
