About $3000 worth of Intel --- mainstream SSD's = 240GB space (6 in raid 10) today, 2x to 3x that storage area in 1 year. Random reads are even easier, provided you don't need more than 500GB or so. And with something like ZFS + L2ARC you can back your data with large slow iops disks and have cache access to data without requiring mirrors on the cache ($3k of ssds for that covers 2x the area, then). -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
