We ran HD Tune after updating to the beta build of firmware version 1.5 and executing a secure erase. The results are similar to those obtained with firmware 18.104.22.168, so let’s see how things change on a formatted drive using our revised test procedure.
In the two bar charts below, we compare the DXTI for transfer/copy workloads in firmware 22.214.171.124 and 1.5 beta. The difference is remarkable. The beta version of 1.5 effectively mitigates the slowdown previously observed. The only odd behavior we noticed was a lock-up that occurred when folders one, two, and four were deleted at the same time. Our test platform became unresponsive for several seconds, which OCZ agrees is likely related to the garbage collection process working in the background.
Firmware 1.5 Beta
Now, we run the same test using OCZ's final release of firmware 1.5. Copying folders one and two happens faster than it did in the beta; however, subsequent transfers behave a lot more like firmware 126.96.36.199.
