I've just read this again (to see if it offered any insight into the "correct" way to work out seek time from access time). One thing I noticed was the apparent importance of burst rate, due to the likelyhood of cache hits:
In the light of this, it would seem possible the Maxtor ATA drives may benefit from using UDMA-133 as opposed to UDMA-100. Since TB3 only uses UDMA-100 it would seem that these drives are not being allowed to work at their fullest performance.
Therefore it seems to me that to make fair comparisons, a UDMA-133 compatible controller should be used. At the least, it would seem a good idea to test a current Maxtor drive (eg. DM+9) again using a UDMA-133 controller, testing both in 133 and 100 modes and seeing if there is a significant difference in any tests. If not... then the current tests are valid, but if the difference is significant then I think the published tests should reflect this.
I'm not saying that using UDMA-133 will make much difference; I really don't know.
I'm using UDMA-66 for drive :wink:
