The white paper “Two May be Better than One: Why Hard Disk Drives and Flash Belong Together” has been posted at http://www.snia.org/forums/sssi/knowledge/education/.  The paper discusses the use of both solid state storage and HDDs in the same system.  Specific mention is made of Paired Storage, a configuration where a small SSD allows fast boot up and quick access to frequently used files and the HDD provides high capacity at a low cost per GB.

The Enterprise Solid State Storage Performance Test Specification v1.0 draft has been posted at http://www.snia.org/publicreview/ and is available for download.  [Update: released specification is now available here.]

The Enterprise SSS PTS provides a standard way of measuring the performance of SSDs for Enterprise applications, thus enabling fair comparisons of SSDs from different suppliers.

It is anticipated that final release of the Enterprise SSS PTS will occur in April 2011.

Work is ongoing in the  SSS Technical Work Group on development of a Client SSS PTS.
