Be sure to test the performance of the device when/if you get it. A lot of SSD's out there don't perform any better than spindle drives. In fact, I recently got one of these Samsung drives... http://tinyurl.com/38s3ac3 The spec sheet says sequential read 220MB/s, sequential write 120MB/s... Which is 2-4 times faster than the best SATA disk out there... And of course, negligible seek time and latency ... But in practice, I find that drive is no faster than my cheap 500G sata disk. Or maybe just barely faster. Not much. You can't go wrong by adding more RAM. Until you hit the price barrier. Before you start building l2arc. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
