why no more ATA-133 support?

I built my last computer in Spring 2001, and at the time everything
was coming out with ATA-133 IDE. Both my motherboard (Intel 815
chipset-based) and the drives I bought supported it.

i recently purchased a new motherboard, & when i was looking, I
noticed that none of the current Intel chipsets support ATA-133, only
ATA-100 max plus SATA. I ended up buying an Intel 865G chipset-based
motherboard, which says it's only ATA-100, though the BIOS shows my
drives detected as UDMA mode 5. I'm using my old drives, but briefly
looking at newer drivers, I notice many are only ATA-100.

just out of curiosity, anyone know why vendors seemingly have dropped
133? i can't imagine it matters in the real world on a home PC, i'm
just interested.

thanks

Well ATA-133 like ATA 100 is marketing hype as you suspected. The drives are
well below those numbers in read speed.
I you are serious about a new drive look at the data shown at
storagereview.com.

Your 815 is ATA100, at best (early ones are ATA66 max), and, to my
knowledge, no Intel chipset has ever supported ATA133.

ATA133 was a Maxtor 'initiative' and not everyone decided to hop on the
bandwagon. Intel is one and Western Digital is another (WD drives are ATA100).

The manufacturers are all in the midst of switching over to SATA harddrive
controllers.
