Older motherboard tends to only support IDE hard disk. If your motherboard is one of the old school type, then you may suffer if you want to use SATA hard disk. You can still use IDE hard disk but you can get better space for the same price if you buy SATA hard disk. Not only the price and space, SATA hard disk differ a lot than IDE hard disk in term of speed.
Instead of buying new motherboard that supports SATA hard disk, the better solution is to buy IDE to SATA converter that you can get from pc shop for not so expensive price. You can get it for RM15 – RM20. If your nearest PC shop doesn’t sell IDE to SATA converter, just buy it online. RM5 for shipping is not a big issue compare to the price that you need to pay for buying new motherboard.
Before you buy new hard disk for your PC, please at least know one thing; that is ATA and SATA is different though they sound quite similar. ATA 100 and ATA 133 have IDE port. It will be bad if you buy wrong hard disk thinking that your motherboard supports SATA.
