[geeks] R720 NAS, continued

[Mark Benson]

Hi,

Yeah I paid extra on both our Dell R-series 1Us specifically to get 3.5b

drives. Their 2.5b
 options were either too small, fast and super-expensive
or the right size (multi-TB) amd specs suggesting theybd be painfully slow.

I guess 2.5b
 is fine if you can afford to drop $500 a drive for 2TB drives
that actually keep up.

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.

realized HOW MUCH slower.  Dear gods.  They are GLACIAL.  It's like watching
grass grow.
