In all of our recent solid state disk (SSD) coverage that featured one of Intel's X25-M drives, a common, underlying performance trend consistently emerged. The Intel drives were always amongst the top performers in read performance, and were unquestionably the best with regard to random writes. However, in sequential write performance Intel X25-M SSDs always seemed to trail competing offerings.
While trying to gain some additional insight into the situation, we had a couple of off the record conversations with some folks at Intel , and asked if the company had any plans to optimize sequential writes on their SSDs, but we didn't get a specific answer other than the standard company line about possible optimization coming with future firmware updates. Based on some rumors we had heard, we also asked if Intel had been deliberately holding back the sequential write performance of their drives for one reason or another, to which we weren't dignified with a response. But today, we can't help but think there was something to those rumors.
