I just love how Google datacenters are somehow &quot;the real world&quot;. Nice, cool and controlled temperatures, batch ordering from vendors knowing they are shipping to Google, stable&#x2F;repeatable environments, not much mention about the I&#x2F;O load, etc.<p>And then there&#x27;s<p>&gt; Ignore Uncorrectable Bit Error Rate (UBER) specs. A meaningless number. 
 ...<p>&gt; Bad news: SSDs fail at a lower rate than disks, but UBER rate is higher<p>meaningless, it is.<p>The real world has wild temperature ranges, wilder temperature _changes_, mechanical variations well above and beyond datacenter use, and possibly wil wild loads (e.g. viruses, antiviruses, all sorts of updates, etc. etc.).<p>It is easier to do stats this way, though.
