Perhaps you should also consider ddrdrive I work a lot on flash... and I've got to say... dram is a lot faster. Mostly because of design/implementation limitations in the present controller technologies. Restrictions about which blocks can be erased and when, and how many erase in parallel, under which circumstances etc etc blah blah. That's mostly where any delay comes from. Straight out of the box, SSD's perform very well. But in real life, only moderately well. _______________________________________________ zfs-discuss mailing list firstname.lastname@example.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
