Hey Yev or Brian,<p>First I think it is awesome that you guys come on HN to respond when backblaze makes the news. Thank you.<p>If you bought a prebuilt storage pod (from somewhere like <a href="http:&#x2F;&#x2F;www.backuppods.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.backuppods.com&#x2F;</a>) could you start out at less than capacity and add more as you go?  Say you started with one drive -- would it need to go in a specific location?  When you add more would there be a significant reconfiguration process?  Is it possible to hot-expand?  I guess location and config has a lot to do with software involved.  Has there been a blog on the software side of managing that much storage?  Can it be as simple as a spanning partition to treat all drives as a single drive?<p>Also, are you tracking the cost of SSD drives?  Do you expect cost parity soon?  It seems that capacity parity is getting close, but cost parity (especially at that capacity) is farther off.  Do you have an estimate of when it might be or is it &quot;far off, check again in 5 years&quot;.  I&#x27;m sure you all found the ssd endurance test at techreport interesting (<a href="http:&#x2F;&#x2F;techreport.com&#x2F;review&#x2F;27909&#x2F;the-ssd-endurance-experiment-theyre-all-dead" rel="nofollow">http:&#x2F;&#x2F;techreport.com&#x2F;review&#x2F;27909&#x2F;the-ssd-endurance-experim...</a>).
