[geeks] R720 NAS, continued

[Phil Stracchino]

So I've discovered that there's a non-obvious drawback to the PowerEdge 
R720 as a NAS.  It's the 2.5" drive bays, combined with the fact that 
ALL 2.5" spinning-rust drives of 2TB or larger are SMR.  ALL of them. 
And to make matters worse they're almost all 5400rpm.

I've heard SMR drives are slower on writes.  We probably all have.  I 
hadn't realized HOW MUCH slower.  Dear gods.  They are GLACIAL.  It's 
like watching grass grow.
