Since its original publication I’ve received a few emails from readers asking if I could expand the essay on SSDs and Lightroom performance to include some additional information. In particular, whether my findings re preview rendering also applied to exporting photos. Likewise, whether using a conventional disk drive connected via the Firewire 800 port rather than internal SATA 300 would change the results. Fortunately, the tests for both are relatively easy to undertake. An updated version of the essay is now available.
