I am using this drive as well. Don't experience any low sustained write speed that you mentioned. Most if not all reviews on this drive are positive. Moreover depending on individual's usage, likelihood of sustained write to the drive is very low.
I think the fellow read the chart wrongly. The chart says "higher is better", but the graph chart shows those drives at top of the charts are lowest sustained write speed, while the fastest sustained writes speed they put at below of chart.
So if you read the chart, "higher is better".....without looking at the write speed, you would interpret those those drives on top are the best, when in fact they are the slowest.
