I write to the drive after a secure erase with iometer - 128KB sequential workload @QD32. I average the cache speed before performance drops and then after it drops I average the remaining writes. (the charts seem to be mixed up slightly - check the last iometer charts for the rest of the write saturation charts until it gets fixed - there you will see the write cliff and better understand the cache)Hi Sean, may I ask how the direct-to-QLC write speed of 185 MB/s was calculated? From the graph "Sequential Steady State Write Workload", I see 287 GB written after 15 minutes. This works out to 319 MB/s.
Also, in your review of the 660p here, the sustained write speed of the 660p seems to be 175 MB/s (not 125 MB/s mentioned in this review). Just some points of clarification please. Thanks.
A direct-to-QLC speed of 185 MBps is perfectly acceptable to me, once the price drops a bit to 660p levels. The improvements in cache recovery and power efficiency are welcome too. Thanks for the very good review.
