I'm in the process of buying a new system, is it worth spending extra on a motherboard that supports ATA100 and the appropriate hardrive or is ATA 66 sufficient. The system will be mainly for games. Any advice appreciated.
According to an article I just read the only time there's a difference in 66 and 100 is when the 100 disk happens to have the next requested data in cache and for which the porbability is small. It's cached data that is moved at 100. Otherwise they read and transfer data at the same rate.
Get an ATA100 mobo & an ATA100 hard disk. They may not offer that much of a performance advantage, but in the longer run, you dont want to be saddled with harware that is already outdated.
MoonBeam is correct. The 100 mbs speed is only the cache burst speed. If the info is in the cache it will send the info to the cpu at that speed. But if it is reading and writing it will only do what the hd can do. And hd's can not read or write at 100. But this also falls under what Airfoil said. There might not be much in the ATA100 area "yet" but you never know what they might come out with tomorrow. Maybe hd's will be able to read and write at ATA100 speeds in the future.
ATA-100 motherboards cost a bit more but as far as I can see, even most value drives are becomming ata-100 so you may as well get the latest stuff, like airfoil says, you may as well get some hardware that won't have to be upgraded for a while.
