Is it possible to change the ATA speed or is this built into the mother board.
My system is ATA 33/udma 2.
I recently added an IBM 75 Deskstar ATA 100.
I also upgraded the connecting ribbon.
Will the slower ATA Effect the performance of my new HDD.
HDD installed top resolve some video editing problems.
Any advice welcome!
The new disk will probably be faster than the one you took out (I'm guessing), but to see it's full speed you will either need an ATA100 motherboard, or a PCI card that you connect the disk to.
Use HD Tach to benchmark your rig for read speed. Technically You need a read speed that doesn't fall EVER below 4mb/sec- but I say double that to compensate for when the disk is getting full.
Hi Mogs
You can use the IBM drive (I am looking to add the same type a second drive and my board will run at ATA 66 and can not get the speed up on my board!) but it will run at the ATA 33 rating to change that you may be able to get a BIOS upgrade for your motherboard. But yes your surmise is correct the ATA speed you can work at is limited by the motherboard.
If your motherboard can not be "improved" you have two choices cahnge the motherboard or get an ATA interface card to plug into a free PCI slot - I think the Promise model was reviewed a while ago in CV Mag.

Only if the drive is capable of >33MB/second transfer rates from the disk itself; ATA100 drives can certainly manage >33MB/second to or from the internal cache, but there are few (if any) which can sustain >33MB/second to or from the disk.
Thanks to all for the advice.
As far as I know the ONLY IDE HDD to be able to exceed 33MB/s is the 75 Gb 7200 RPM IBM dive (I forget the name).
So unless you own that 75Gb IBM drive you will only see minimal (if any)improvements by fitting an ATA 66 or 100 PCI controller card ,& as Mogs mentioned ,the improvement will come from allowing more bandwidth to the internal cache (SDRAM).
