I built a new server for myself six months or so ago.  I put in 6 x 4 TB WD Red HDDs and a pair of Samsung 850 Pro 256 GB SSDs for the OS&#x2F;boot partitions.<p>I <i>really</i> like those SSDs!  I replaced the (about three year old) Crucial M500 480 GB SSD in my ThinkPad W530 with a pair of them and have since put them in every machine I&#x27;ve got (with the exception of my new MacBook Pro).
