You mean their almost certainly doomed by flash drive 10K and 15K drives?  (A class of drive I&#x27;ve been using since 1995 and just stopped buying new ones; in fact, a 15K Savio mirrored system disk recently failed and I replaced both with an Intel enterprise SSD rather than send it in for warranty repair.  So far I&#x27;m not looking back.)<p>Officially, Constellation drives are &quot;Enterprise&quot;, 5 year warranty (which still works well, did that on a 2TB drive last year I think), available in SAS as well as SATA interfaces.  Although they&#x27;re now saying that you shouldn&#x27;t transfer more than 550TB of data per year through the best of this class of drives.
