SSD firmware update …
Before starting the tests, we’ve updated the Plextor SSD to the latest firmware version. The SSD was delivered with firmware 1.02 and at the review date, Plextor offered the firmware version 1.03. Of course a test with the previous version was made as well, but it was not as fast and not so safe like the current one. The update of the Plextor firmware is relatively simple: Download the latest firmware from Plextor, burn the px-256m5pro_1.03.iso ISO file to a CD or transfer it with a suitable software to a USB stick, boot with this CD-ROM or USB thumb drive and confirm the SSD firmware update.
