[geeks] R720 NAS, continued

[Kevin Lee]

I have 24 2.5 inch seagates 5tb each smr.  Running raid 2z2 58tb storage
about.  Yeah 30-50mb writes but Ibm mostly store and do nothing anyway so.

So get a used dell with 12 bay 3.5 inch sas drives.
10tb are about 80 bucks a pop used flea bay and run sas 3. Cmr. Your sanity
will thank you.

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.
