I think both my motherboard and Hard disk drive support SATAII. But Intel Active Monitor reports the max UDMA transfer mode as UDMA-7 and active transfer mode as UDMA-5. Everest Home reports the max UDMA transfer mode as UDMA-6 and active transfer mode as UDMA-5.
I did some googling and found this:
I have two WD HDs that are SATAII w/16MB Cache.
However, Intel desktop Utilities Version 2.1 Light is saying
Max transfer mode = UDMA 6(ATA/133)
Active Transfer Mode = UDMA 5 (ATA/100)
They don't seem to be transferring as fast as possible.
What do I need to do to optimize these drives? Thanks!
You don't have to do anything. They are already either transferring at 150MB/s if you have them set to run on a SATA1 bus, or at 300MB/s if it's running on a SATA2 bus... the BIOS and all programs that report these specs just read the active transfer mode as UDMA 5 instead of (what should technically be) UDMA 8 (UDMA 7 being the SATA1 spec of 150MB/s and UDMA 8 being the SATA2 spec of 300MB/s). This is perfectly normal, you do not have to do anything. http://forumz.tomshardware.com/hardw...ict185797.html
But is there a way to make sure whether Iím running UDMA-7/8 or UDMA-5?
If Iím actually running UDMA-5 how can I change it to UDMA-7/8?
It's useful to keep in mind that big numbers are often there for sales purposes. In the IDE era, boards and hdd were listing ATA100 when the actual transfer rates were only ATA66, if they even achieved that.
It's a male thing, this measuring...................
