Apple has taken another step foreword in speed with the 2013 MacBook Airs and the new iMacs. Apple has started switching it's computers over to using a direct PCIe interface for their SSDs (Solid State Drives). So far, the SSDs have been limited to a SATA bus transferring about 400 MB/s, but using the PCIe bus we can achieve speeds up to 800 MB/s.  This new SSD was originally Introduced in the MacBook Air and announced for the redesigned MacPro.  Now the PCIe SSD has made its way into the iMac and is finally available up to 1 TB.  The speed increase is fantastic and there is an added bonus of SSDs using less power than a spinning hard drive.  I believe Apple has made it clear that they are going towards computers with no moving parts, except for fans.  The price of SSDs still has a way to go before most people will consider it, thought it has been getting cheaper each year.  The 1TB option in the iMac is $1000 extra, if we rewind to 2008 it was $1000 for the 64GB SSD in the first Macbook Air.  We’ll have to see what Apple has in store for us, but I see 1TB Retina Display MacBook Pros in the near future, and I can’t wait to test out the upcoming MacPro.
