Thinking of getting another hard drive and my board is sata compatible and i have been given 1 little funny leads and 1 strange looking power lead when i bought it. At the moment i have an 80gb ide hard drive. Can i run both sata and my ata hard drive together? And what are the diffrences?? Any help would be appreciated.

Yes you should be able to run both together. Both are essentially the same although SATA - the S stands for Serial - is likely to be faster at transfering data.


The ATA dirve will be connected with either an 40 or 80 conductor ribbon cable as it transfers data in parallel.

ATA has a transfer rate of 133mb/s, whereas SATA has 150mb/s transfer rate.
For the record, there's also SATA2 which has 300mb/s.

The power lead you have will be to connect your SATA drive to your PSU in the chance that it doesn't support SATA.


if your MB supports both and you have sufficient/appropriate power connectors on your PSU then you can have as many ATA/SATA drives as you have connectors on your MB......


As far as speed/performance is concerned... You'll probably not notice ANY difference at all... the speeds concerned are really indistinguishable from each other in all but the most powerful and memory intensive applications
