IOMeter – Average Transaction Time (Rev 1)
I’ve tweaked this page for HDD results to cover a smaller range of Queue Depth. This helps expand the part of the chart where these drives live most of the time.
As a matter of simple physics, the 10K RPM VelociRaptor remains the king of low latency. The Caviar Black does well regardless of interface speed, but falls slightly behind both 2TB models. That slight increase in seek time adds up here.
I find it odd that the author
I find it odd that the author chides Marvell for the interface performance: in effect doubling the Windows O.S. for transference.
I am bewildered he then goes on to say that the 2TB Drives are faster, but perhaps, should be equalled by the WD1002FAEX.
If the Marvel controller were saturating on the Motherboard, it probably would similarly saturate for the 2TB Hard Disks. Assuming that the OEM PC and the Windows O.S. have not changed, this particular difference must lie within the testing of the WD1002FAEX.
[While it is alleged that] Marvell’s 88SE9123 or 88SE9128 controllers have not been able to deliver improvements to 3GB/sec as suggested; this is partly and largely due to Marvell’s SE91XX drivers having flaws.

Some software requires caching to be disabled. For example, SQL Server. When the driver ignores convention, you have no choice on having a reliable system.
