SSD firmware update …

The tests were done with the first 0001 firmware version as well as with the 0002 firmware, whereby the benchmark results were nearly the same. At the review date, the company Crucial offered the firmware version 0002 for Marvell based SSDs, which offers in comparison to the FW0001 version more safety, a higher TRIM performance and a lower power consumption. The update of the Crucial firmware is very easy: Download the firmware from Crucial, unpack the contained ISO file, burn it on a CD, boot with this CD, select the SSD in the firmware update utility and confirm the firmware update several times.
