HDTach 3.0.4.0
HD Tach will test the sequential read, random access and interface burst speeds of your attached storage device (hard drive, flash drive, removable drive, etc). All drive technologies such as SCSI, IDE/ATA, 1394, USB, SATA and RAID are supported. Test results from HD Tach can be used to confirm manufacturer specs, analyze your system for proper performance, and compare your performance with others. HD Tach is very easy to use, quick, and presents data in easy to read graphs, including the ability to compare two storage devices on screen at the same time for easy analysis.
The caching Marvell driver completely throws off our burst results. If you read between the lines, you’ll note the non-caching Marvell is not bursting as high as it should be. 327 is quite low as compared to the expected ~480 MB/sec for this test.
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
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.
