I got an epox 8k7ta mobo and also an fic ad11 which come with the via 686b south and amd 761 north.Running both win2k and win98.Deal is theres no way in hell i can hit 100mbps transfer on my drives.Max i can hit in win2k is around 58 and in win98 in the 70 or so range.With my previous intel board using the 815ep chipset it maxed out.Im using the latest bus mastering drivers from via and have tried previous versions also.Those fuc** wont reply back to me with a reason why.Im sure is a driver issue cause ive verified this with a few.Just wanna know if somebody has figured out a way around this.thanks

I use HDTACH to test my transfer rates.Drives are maxtor 7200 rpm udma100.Hell with the maxtor controller card or a promise i have it maxes out also at 100mbps

one hd tach is not a good benchmark. 2 no hard rdives hit 100mbps burst rate (well no IDE).

you get lower HDTACH scores i nwin 2k since the program SUCKS under win 2k :p

Yes they do burst at 100 and hdtach is a very nice tool is used by many sites.With the 815ep chipset, maxtor controller card and a promise controller card it burst at 100mbps of the chart reading.With the via 686b south bridge it doesnt go beyond 70 maxed.

You might want to take this over to storagereview, I think your information is incomplete in spots.



<< ATA100 means 100 is the max burst.... >>



Well sort of, ATA100 means the maximum bandwidth available for file tranfer is 100,
but that has nothing to do with the physical capabilities of the drive itself.

Sustained transfer rates on the fastest IDE drives available still do not exceed the ATA66 spec,
most do not exceed the ATA33 transfer rate.

Burst transfers take place from the Drives internal cache.
The biggest cache on any Maxtor drive out there is 2048KB (2 Megabytes).
Think about this... once any data has been transferred from the cache, the drive has to
drop back to its sustained transfer rate to keep up with any further requests for data
until it has a sufficient break to refill the cache. In either case, it might burst the first
2M at the full bandwidth (still highly doubtful) but it will immediately slow down the
measurement once it has to change to some other way of providing data beyond that
first 2 Meg.

Instead of trying to flame VIA for the rating you are getting from HDTACH, maybe you need to be calling
Promise to find out why thier controller is not giving you an accurate reading of what is really going on
with your drive.

HDTACH is a nice tool, but it is not the only tool, and even its readings have to be evaluated against
the real world capabilities of the technology to give you an accurate idea of what is actually possible.
