I would like to buy 5400 rpm Hitachi hdd but i dont know what to buy because of ATA-6,ATA-7,ATA-100,ATA-133,S-ATA !I dont have any idea about these.What kind of 2.5" hdd i must buy?

 

It's an IDE = ATA = PATA HDD.

 

this is what it is writing at pc wizards
Support : ATA/ATAPI-6
Size : 60 GB

 

is this mean i have to buy ATA-100 or ATA-133 2.5" hdd?

 

Can't really tell on the internet. You should just take a look at your HDD, should be written on there.

 

thanks,i'll buy ram tomorrow,so i can check hdd when i install ram!

 

There's no need to open your computer. Device Manager will give the the model number of your HDD. Then Google that model number to find the full specification.

thank you so much ratsey!Here what i got at toshiba page for my hdd (mk6025GAS);

http://www.sdd.toshiba.com/main.asp...Drives/ProductIndex-HardDrives/MK6025GASspecs

it's writing;
Rotational Speed 4,200rpm
Average Latency 7.14ms
Interface ATA-2/3/4/5/6


so now i confused again ,what is ATA-2/3/4/5/6 means?

 

It means it's compatible with those kinds of HDD. There were many ATA specifications.

 

yes but does it mean any ATA-100 or any ATA-133 is ok to buy?

 

Yes, get anything which is not SATA (serial ATA - which has a different connector).

What used to be called ATA may now be referred to as IDE or PATA (parallel ATA). but your ATA-100 or ATA-133 are fine.

thanks for your interests guys!

I better buy ATA-100,i found some 16mb and 8 mb cache hdd,is it making big difference?

 

In theory, 16MB cache should give better performance but I don't think it will be a big difference.
