Now you've got me wondering what the > difference between the earlier and current 96XX models really is. 9650 was made by 3Ware, essentially a PCIe version of the 9550. The 9690SA was from some sort of acquisition/merger. They are not the same product line at all. 3Ware, IIRC, has its roots in ATA and SATA RAID. I gave up on them after the 9650 and 9550 experiences (on Linux) though. > > -- > Greg Smith 2ndQuadrant Baltimore, MD > PostgreSQL Training, Services and Support > greg@xxxxxxxxxxxxxxx www.2ndQuadrant.com > > -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
